As title, thanks.

Since D1s has 3 SDIO, can we use SDIO3 for wifi ?
In such case, we can boot the D1s from SPI nand.

Is there a DTS for the board anywhere? I'm interested in targeting a buildroot for the board and I'd need that to start. I assume you must have had one to build the Tina images.

I and few of us would like to do a group buy, do you have a manufacturing plan or any pre made boards with you ?

We are discussing about it here, please join in if possible: https://discord.gg/g2QrdxpZ

Any further info about the external LAN HW module?

Hi, I've got some of the chips and I plan to implement your board or a similar one.
Where to get the firmware images? Are them open source, at least partially?

Hello! I got one of the boards that cnx-soft made a while back. I'm sorry it sat on my to-do list for so long. Jean-Luc had problems sourcing some of the caps so my board needed some soldering done before it was useable and I'm not all that fond of such tiny SMD work, so it's taken me a long time to get it done. But I finished it today! We had to sub in caps for the XTAL loading caps, but they should be good enough. I was one 0.1uF cap short and I chose not to populate the cap across the reset switch. I think I chose poorly because it seems that cap also helps time the initial reset signal. Pressing the button resets it, so that's fine.

The problem is that the board won't load Linux. Here's the capture of the boot process:
D1S_1.txt

OpenSBI loads and finds the SD card, but it doesn't seem to like what it finds. FWIW, voltages look good, the board runs cool. I will try other uSD cards just in case it doesn't like this one. Thank you!

Thank you for sharing your great work.
I made my F133-A board based on your schematics but it doesn't boot.
There is no serial console data from the UART TX pin (PE2). I set 115200N81 on minicom.
I flashed your prebuilt test image on a micro SD card for my hardware bring up.

I checked power rails and 24Mhz/32.768Khz oscillators work fine.
3.3V: 3.328V
1.8V: 1.813V
Core: 0.908V
LDO_B: 1.379V (!)

When I connected the USB Port 0 to my Linux PC, I could see "ID 1f3a:efe8" from lsusb output.
It seemed that the FEL mode worked at least.

I've checked the SD interface CLK and CMD lines with an oscilloscope. But they were always low (zero volt).
I think BROM didn't try fetching any boot data from the SD card.
I didn't connect any resistors to the boot mode select pins (MOSI/MISO).

Can you please tell me what I am missing?

Thanks in advance,
