Is it possible to port drivers support to OpenWRT distribution?
The following commit 3afed37 have an issue with compiling, the function get_port_link(...) doesn't exist.
Enabling BR2_PACKAGE_LIBGLIB2=y (e.g., for wireshark) results in a build failure. See attached log file.

Hi!
In sysfs it has ability to turn on/off port in RSTP via /sys/class/net/eth0/sw0/0_stp_on. But it works strange. For example, if there's link on a port, to turn off the port from RSTP via sending 0 to 0_stp_on works, but until reconnecting the port, the next time it's working again. Is it possible to turn on/off port in RSTP permanently, not until link changing?

static void i2c_wrreg_size(struct sw_priv *priv, u8 reg, unsigned val, size_t size)
The i2c_wrreg_size function on Linux-4.19 driver uses an u8 for the I2C 16bit register addresses.
sw_get_br_id() should not return a pointer to "id" located on the stack (invalid after return).
This will also fix a compile warning (want all source to compile without warnings).
My local fix is to change "id" to a static but it assumes that only one thread executes this at a time (likely to be ok).

While inspecting code, trying to figure out generically why I cannot get ACL to work with the KSZ9477, I saw these two lines of code. Is this a bug?
Are you planning to upgrade linux kernel to 4.14 version?
I'm trying to adapt KSZ8463 drivers for Linux 4.14 kernel with PTP support from EVB-KSZ9477/KSZ/linux-drivers/ksz8463/linux-4.14.
The communication between SOC and the switch chip goes via SPI and seems to work fine. I can set, start and read the PTP timer via direct access to PTP_CLK_CTL and PTP_RTC_xxx registers and this works fine as well.
The issue is that even though I can set and read the timer via /dev/ptp0 device, the timer always stop after doing so. It appears, that the access to the timer via ptp0 device always resets the PTP_CLK_ENABLE bit in PTP_CLK_CTL.
In case of KSZ9897 driver the PTP_CLK_ENABLE bit is set in initialization, in ptp_hw_enable function, but in case of KSZ8463 there is nothing that would set this bit.
We are seeing problems booting from SD version 3 cards. The failure is somewhat random but failure is much more likely. This occurs when u-boot attempts to load the uboot.env file.

It seems that after RomBOOT loads u-boot the SD card is left in a state where partition 1 is not accessible. But after u-boot attempts to load uboot.env, the fatls and fatload commands work fine using "mmc 0:1".
After some trial and error, I found this patch fixes the loading of uboot.env:
sama5d3_xplained.c.txt
and the board then boots linux successfully.
The patch cycles the power on the SD card once just before uboot.env is loaded.
However, all is not well. If you interrupt the boot in u-boot, the "mmc part" command fails. There are also errors if one attempts to change the default device and partition with "mmc dev".
Don't know enough about SD cards or u-boot to fix this.
Hi
I'm struggling configuring the EVB-KSZ9477S properly for SFP port use. I'm able to send traffic to and from the Linux through the SFP port after setting up the registers manually through regs_bin to enable SERDES/negotiation. However, I can not manage to forward data between any other switch ports and the SFP port. I've tried to set the port control registers as well, but no luck. Is there a way to make linux see port7 (eth0.207) as it does with port 1-6?
If someone made Switch-2-Switch SGMII/SERDES working with forwarding to other ports could you give a short guide on configuration change needed?

(PS: I know this is more likely a config issue than a code issue, but as documentation is also supplied in git and I've been through it all I hope this is still relevant as an issue)
Hello,
We have a board with an iMX7 connected to a ksz9893. i2c is used for register access.
I've integrated the files under KSZ/linux-drivers/ksz9897/linux-4.19 in our 4.19.35 kernel (taken from the linux-imx).
When compiling the i2c_ksz9897 driver as a module it worked.
Now i'm compiling it statically in the kernel and there are issues:
There are differences between loading the module statically or dynamically.
[ 19.795300] Microchip KSZ9893 Switch sw.0:01: attached PHY driver [Microchip KSZ9893 Switch] (mii_bus:phy_addr=sw.0:01, irq=81)fep->port.sw will be NULL, with static compilation this is filled in. The code takes different paths based on this.Is it normal for the ksz phy driver to be used for the cpu port? I'd expect this to be a fixed-link (as we have configure in our dts file). And have the ksz phy driver used for the switch ports. But we're not using multi_dev, so that's not applicable.
thanks,
Cedric

Module 16: PTP messages get dropped in PTP 2-Step Mode
Hello, I can't change the value of hello time stp_br_hello_time.
Hello,
We are evaluating the KSZ9477 and ATAMA5D36 (with EVB-KSZ9477 UNG_8071 rev B).
Having a clean, stock build from this repository (kernel 4.9), we are having link issues when interconnecting development boards.
It is not consistently reproducible, nevertheless there is an easy way to trigger the issue:
PC - DEV1 - DEV2 - DEV3
Connect your interface to DEV1, random port. Link trough DEV2, random port. Link trough DEV3, random port.
Let PC generate some traffic (we broadcast some UDP packets).
Ping all development boards.
Repeatably disconnect and reconnect random links.
After a while (let's say 20 link toggles), suddenly one (or multiple, depends on which port is "broken") pings are not replied anymore.
When connecting to the "faulty board" we see at this broken port, by getting it's mib counters (e.g. cat /sys/class/net/eth0/sw3/3_mib) that tx_discards are increasing.
We haven't found a way recovering from this issue other than rebooting the board.
Things tried:
• Force power off/on toggle on PHY:
echo 0 > /sys/class/net/eth0/sw3/3_power
echo 1 > /sys/class/net/eth0/sw3/3_power
• Force new gigabit negotiation of PHY:
echo 1000 > /sys/class/net/eth0/sw3/3_speed
echo 0 > /sys/class/net/eth0/sw3/3_speed
• Toggle duplex (although this should have the same effect as speed):
echo 1 > /sys/class/net/eth0/sw3/3_duplex
echo 0 > /sys/class/net/eth0/sw3/3_duplex
• Toggle transmit:
echo 0 > /sys/class/net/eth0/sw3/3_tx
echo 1 > /sys/class/net/eth0/sw3/3_tx
(Unloading/loading the driver has not been tested yet)
We tried as well using the DSA driver and seemed not able to reproduce the issue.
So we might expect (and hope), it's somewhere a driver (software) issue?
Is it advisable to use the DSA driver? Is it complete? Is it possible to run PTP on the DSA lan interfaces?
Many thanks in advance!
Kind regards.
When default REG_PORT_XMII_CTRL_0=RMII the driver still decide to use RGMII.
There is a lot of "#if 1" code in this file, which often is a sign of unstable code sections.
Also the typecast of data to data_hi / data_lo looks suspicious and makes code harder to read.

Hello,
I would like to add drivers and device tree entries for KSZ8567 and KSZ8873MLL.
I'm running Linux kernel 4.14.98 on an NXP IMX8 SOM.
Can you please recommend which driver is compatible with these ethernet switches and hopefully a device tree entrée example?
Thanks,
Amit

Hi,
I am working on Yocto Linux for iMX6 processor. I am looking for Linux drivers for KSZ8863 switch to work with Linux kernel version 4.9. I tried the files available in https://github.com/Microchip-Ethernet/EVB-KSZ9477/tree/master/KSZ/linux-drivers/ksz8863/linux-4.9/drivers/net/ethernet/micrel path. I am facing build errors for this repo. Attached the error log files.
And I tried to build the kernel available for Atmel board at https://github.com/Microchip-Ethernet/EVB-KSZ9477/tree/master/KSZ/kernels/linux-4.9.143 for KSZ8863, I am getting errors listed in atmelErrorLog.txt
Kindly help in this.
Regards,
Naveen.
Hello,
I'm trying to integrate a KSZ9477 on a NXP imx7 using your fec_main patch.
We're facing a kernel panic because of NULL pointer when we use an other iface than the first one.
Attached is the full kernel trace.
It seems to be an issue in "fec_enet_start_xmit" function.
At line : txq = fep->tx-queue[queue]; txq is NULL. I think it's because we are trying to get a queue from fep, and fep is a pointer on a"fec_enet_private" struct from a net_device that is not the first one, no tx_queue as been set for the fec on port other than the first one.
We were able to correct it adding the lines at the beggining of "fec_enet_start_xmit" function if HAVE_KSZ_SWITCH is defined :
if(fep != fep->hw_priv) {
fep = fep->hw_priv;
}
The beggining of the xmit function is now as follow :
static netdev_tx_t
fec_enet_start_xmit(struct sk_buff *skb, struct net_device *ndev)
{
struct fec_enet_private *fep = netdev_priv(ndev);
int entries_free;
unsigned short queue;
struct fec_enet_priv_tx_q *txq;
struct netdev_queue *nq;
int ret;
#ifdef HAVE_KSZ_SWITCH
unsigned long flags;
if(fep != fep->hw_priv) {
fep = fep->hw_priv;
}
spin_lock_irqsave(&fep->tx_lock, flags);
#endif
If I understand well, we need to use the "main port" (that's the name you gave in macb files) for sending values. Adding this lines force the use of the main port. Am i correct?
When a ksz9477 port operates in slave mode, the memory used by ptp4l grows without limit and eventually ptp4l crashes. Performance degrades when memory usage gets large.
This can be demonstrated with the EVB by editing /ptp/avb/gPTP.cfg. Change priority1 to 248 and clockAccuracy to 0xFE. Restart ptp4l with a couple of AVB devices connected. One should become master. Watch ptp4l memory usage grow in top.
I know the memory is being allocated by msg_allocate (malloc). However, it is difficult to tell why some messages aren't being recycled. Possibly, this is related to PTP errata for device and/or the loss of TX timestamps.
My requirement is to interface an i2c with ksz9897 for linux kernel 4.14 version. I came across many ksz9897 drivers for different versions, I am only looking for 4.14
I've noticed that new crashes when using SPI operations, even openning web interface (we use KSZ9567R)
There is kernel message:

Hi,
We want to access the KSZ9897 using spi interface on X15, We are using the 4.4 kernel. Is there a Linux git repo for KSZ9897, with latest Linux kernel version ?
Is there any documentation on accessing via spi, and merging with latest kernel ?
Cheers,

Hi,
I'm using the ptp4l tool for time syncing between devices. I need to implement a feature where the GPIO_1 output is disabled (i.e. output is 0) and when the ptp4l becomes locked I need the GPIO_1 to output 1PPS in sync with the internal clock.
By default I get the switch outputting 1PPS on this pin. I tried writing "0" to flag 3 of register 0x052F which disabled the 1PPS output but I could not get it back running by writing "1" to the same flag. Tried toggling flag "2" but with the same result.
I did notice that restarting my mac driver revives the 1PPS ouptut.
Any suggestions on how to proceed?
Thanks
Emil
Hello ,
I am working on integrating KSZ8563 switch to Olimex A20-SOM which uses Allwinner chip and Linux-sunxi system which supports STMMAC (not macb or freescale) as MAC driver. So far, i have intorduced KSZ9897 driver into linux kernel and integrated into stmmac (dwmac-sunxi driver) with CONFIG_KSZ_EMBEDDED according to setup_sw.c and i have taken macb as a reference. I can see that driver is integrated successfully and ksz9897 driver functions can be called from stmmac driver successfully. If i set STP state FORWARDING and disable TAIL TAG, i can ping and communicate with host CPU without problems. I can also send all PTP messages with "ptp" application of the library or with "linuxptp" without problems.
When i activate IEEE1588 PTP and tail tagging (only for host port). I cannot ping or communicate with the device anymore. As errata indicates, LENGTH CHECK is disabled by driver and i checked it. When i try to send PTP messages from "ptp" application, i can see SYNC messages on remote but as malformed. When i compare received package with the transmitted, i see that last 10 bytes is removed by switch but i expect that switch should erase 5 bytes (4 bytes for PTP and 1 byte port tag). I cannot see any PTP messages like announce when i try to send it with "ptp" application. I can see the DHPC Requests on remote side but it is also malformed like SYNC. So, it seems some packets are dropped by switch (like ping or ANNOUNCE) and others sends in malformed way (like DHCP or SYNC) with 10 bytes removed from back (i expect 5 bytes only for tail tag). When i check mib stats of the ports, when i ping, host port TX count increases but TX count of switch or ports don't increase.
When i establish another setup i disabled PTP support and enable tail-tag, 1 byte is inserted at the end of every packet but 2 bytes are removed at the remote side. I again can get DHCP req but as malformed.
I try to explain the problem as far as i can but i stucked at this point. So could you tell me what could be the problem ?
Best Regards
Fatih
Hello,
I compiled the kernel in vanilla configuration (make atmel_sama5d3_xplained_ksz9897_mmc_defconfig) for my EVB-KSZ9477 board.
Made sure I was connected on 1GbE (on a single port 2, other ports no connected) and run an iperf3 test.
I got 167Mbits/s. Seems that the bandwidth is 1/6'th of the maximum.
This doesn't make sense to me... Does the BW/traffic is somehow being split between ports?
How can I get full bandwidth?
Thanks
Emil
I am new to the KSZ9477 and SAMA5D36. While reviewing some of the literature it said it would be possible to connect the MPU with a serial cable. When I connected the cable and booted the KSZ9477 I was only able to see garbage text.
Do I have to load the Linux software first?
From the literature I was under the impression the Linux software was pre-loaded.
Thanks for your help.
Regards,
Dennis

I can flash the image files from windows but so far I haven't discovered the magic to create the file ubootEnvtFileNandFlash.bin. The file uboot.env is created in a mmc build but not in a nand flash build. I looked at the two ubootEnvtFileNandFlash.bin files that I have. However, they don't seem to be standard uboot environment files.
How are they generated?
It may be flash_board generates the default uboot environments...

And I found functions in setup_sw.c are useful to setup ksz9477, but is seem dose not in the driver of ksz9477, how to use this?
EVB KSZ9477 Software Setup Guide
Rev 0.4
July 28, 2017
While trying to setup HSR configuration I've met this document EVB_KSZ9477_Software_Setup_Guide.pdf to be confusing.
eg.
7.4 High-Availability Seamless Ring (HSR)
is metioned to setup different MAC addresses for both HSR ports refering to 4.2 how to do this.
However instead of 4.2 should be 5.2 and there is only specified how to setup only one/first MAC address - not mentioned how to do this to the second, or other ports.
I'm compiling the KSZ9897 (a ksz9567 switch) driver for kernel 4.14, but am getting several compilation errors, some of which seem to be reverts from the most recent commit. Was there a reason for these reverts?

.end = KSZ8462HLI_PA_CMD + KSZ8462HLI_SZ - 1,
.flags = IORESOURCE_MEM,
},
[2] = {
.start = IRQ_KSZ8462HLI,
.end = IRQ_KSZ8462HLI,
.flags = IORESOURCE_IRQ,
},
};
static struct platform_device *pdev;
static int __init ksz8462_add(void)
{
int inst_id = -1;
int err;
pdev = platform_device_alloc("ksz8462_hli", inst_id);
if (!pdev) {
err = -ENOMEM;
pr_err("Device allocation failed\n");
goto exit;
}
err = platform_device_add_resources(pdev, ksz8462hli_resource,
ARRAY_SIZE(ksz8462hli_resource));
if (err) {
pr_err("Device resources addition failed (%d)\n", err);
goto exit_device_put;
}
err = platform_device_add(pdev);
if (err) {
pr_err("Device addition failed (%d)\n", err);
goto exit_device_put;
}
return 0;
The driver is loaded, but I have a problem when the driver get the device ID:
[ 19.758130] ksz8462_hli ksz8462_hli: failed to read device ID(0x0f)
Iin fact, I am not sure on how to drive the logic (CSN, RDN, WRN) from the device driver itself and for sure, also about both define KSZ8462HLI_PA_DATA & KSZ8462HLI_PA_CMD regarding the raspberry registers.
Any help will be appreciated :)
Thanks!

sw_get_br_id() should not return a pointer to "id" located on the stack (invalid after return).
This will also fix a compile warning (want all source to compile without warnings).
My local fix is to change "id" to a static but it assumes that only one thread executes this at a time (likely to be ok).

Hello, I've tried to use Web interface, but it works not so fast as I expected. How can I improve the webpage loading speed? Especially loading information about port configuration and VLAN (PVID).
Hi!
I'm using KSZ9567R, in at91-sama5d3_xplained_ung8071.dts it's ports description like
ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; label = "lan1"; }; ... };
How can I remap port order for example if I want to make 3rd physical switch port like 1st port of device?
The header does not seem to match the source.
One of the errors as an example:
There are references to (struct * macb)->config, but the macb struct in the header doesn't have this field.
macb_main.c#L3104-L3105
macb.h#L1013-L1110
Some of the other driver files also do not compile, but that may be because I'm using the IMX Linux 4.14 kernel and there isn't a mistake in the driver.
Hello,
I plan to use the KSZ9897S switch to connect to the CPU through the SGMII port. The host processor is qualcomm arm with modificated linux kernel 3.18. SGMII provided by qcom_emac.

Is it possible? What drivers should I use?

Hi all,
I want to run KSZ9477 as 2 step transparent clock. I expect to get correction factor of Followup message to be updated .
However, when i am enabling 2 step mode by setting 515 as 78h then Sync & Follow Up messages are getting dropped and only receiving Announce messages on other ports.
Can anyone explain this type of behavior in KSZ9477 switch ?
Hi,
I'm running Linux Yocto 4.1.15 using an NXP i.mx6s ARM processor with the KSZ8895.
I've managed to get spi-ksz8895 to compile to a .ko, and i can manually modprobe to mount it.
I've read the README but i'm not clear what i need to do to use the switch driver. Do i have to compile and run the sw_setup to setup the switch, and then ksz_sw_sysfs_8895 to create a /spi0.0/sw interface?
Hello,
I am a beginner and new to this community.
I want to boot the EVB-KSZ9477 board and I followed the instructions given in EVB-KSZ9477 Image Programming Guide for SD card but I am not able to boot the board with it.
After doing SD card Image programming as per the instructions given in the Image Programming guide, when I put SD card in EVB-KSZ9477 SD card slot, powering up the board and connecting it with computer with USB cable and doing the MCU reset button the board is not able to boot with SD card and build root login terminal doesnot appear.
Am I doing it the right way or am I missing some thing?
Please guide me with a solution.
Thank you,

Hello,
I plan to use the KSZ9477S switch to connect to the dp83867 phy through the SGMII port. when seteenv sgmii is 2, after boot,it cannot ping serverip(192.168.0.210),sometimes ping ok just once.
Is it possible? What drivers should I use?
I am attempting to get device level ring running between two KSZ9477 eval boards. Currently, by following the steps in the software guide, I am unable to run the echo command as there is no dlrfs directory. When I attempt to run in bridge mode I am finally able to get functionality, but I am unable to pas traffic through the other ports of the board.
I have had the same outcome with the software on the board from the factory and software built form here.
Thanks,
