tangnano-9k-example's Issues

problem compiling provided .c files

Sorry for the question, i'm a begginer and fell like some things of the picotiny are not well documented, like the addresses of peripherals.
When i clone the repository and flash the default example file provided, it works like a charm, but when i compile and flash the UART won't respond at all and the HDMI output shows the default background and some garbage.

this is my toolchain
RISCV_NAME ?= riscv-none-elf
RISCV_PATH ?= /home/gusta/.local/xPacks/@xpack-dev-tools/riscv-none-elf-gcc/13.2.0-2.1/.content/

Can someone help with tips for compiling, the adresses os peripherals and how to get simple UART input output from the provided code?

Issues about using GAO

I can download .fs files via gowin programmer. But when I open GAO, the system shows that "Fs file download failed". How to fix this problem?

Anyone got pong to work?

There is an unused file (as far as I can tell) TangNano-9K-example/picotiny/hw/hdmi/svo_pong.v Looks like it emulates the old Atari Pong game. Any ideas how to make it work?

Thanks for any help.

404 Page not found (link to led demo in README.md)

Broken link (404) in :

"Demo project for drive LED and on board led. The related LED tutorial can be found at https://wiki.sipeed.com/hardware/zh/tang/Tang-Nano/Tang-nano-9k.html " - gives a 404 error

The sipeed site has apparently been reorganised, since this readme was last updated, so there may be other broken links.

HDMI Example ?

I'm trying to port my HDMI example from tangnano4k to tangnano9k but I have some problems with TLVDS_OBUF.
https://github.com/Martoni/HdmiCore

ERROR  (CT1005) : Conflicting multiple constraints specified for location of Instance 'O_tmds_clk_p'(type: TLVDS_OBUF); Or constrained location for the Instance is not available; Or constrained location type is not matched with the instance

Is there an example using HDMI/DVI with TangNano9k ?

Thanks

Best Way to Debug?

Hi there!

I have been tinkering with my nano 9k for a while now. I was wondering about how you debugged and coded picotiny.
I was trying to use GAO but is that the best way?

Imagine one wants to write a new riscv for nano 9k. What' the best approach and what are available debug tools?

I appreciate your answer in advance.

BL702 UART firmware update on Tang Nano 9k

I tried to drive 1Mbps uart to the BL702, but I see incorrect data. I can drive the same uart data to a board pin and look at with my logic analyzer (pulseview) and it looks fine. My Tang Nano 1k board uart works fine after I updated the CH552 firmware. Does the BL702 firmware need to be updated?
Thank you.

Picotiny example fails during Place & Route

With Gowin_V1.9.9Beta-4_Education it seems I'm unable to place and route the picotiny example.

ERROR (PA2122) : Not support 'mem_mem_0_0_s'(DPB) WRITE_MODE0 = 2'b10, please change write mode WRITE_MODE0 = 2'b00 or 2'b01.

I've tried to read through https://wiki.sipeed.com/hardware/en/tang/Tang-Nano-9K/examples/picorv.html but such a problem is not mentioned.
This is my first time I tried to build a Gowin FPGA project so I'm a little bit lost. I tried searching for this online but I'm also unable to find anything about this.

Can't flash firmware

Hi,

I can only flash the example-fw-flash.v! When I build a firmware with make flash I can't flash it! Do you know why?

picotiny shows only testscreen

After flashing firmware there is only testscreen displayed via HDMI, UART also isn't working.

Any ideas?

Half of examples no work

Just like other Dev. Boards from SiPEED half of the projects work and half not. I first bought a MAIXDUINO about a year ago. The same thing, no support, only some demonstration projects work. Then I bought an M0P Dock about a month ago, that board never worked.
You are a real disappointment to both yours and the manufacturers whose components you use.
I have no intention of ever buying anything from SiPEED again.

spi_lcd 中的 `ifdef MODELTECH 似乎是错的

原文：

TangNano-9K-example/spi_lcd/src/top.v

Lines 104 to 117 in c3b7957

	`ifdef MODELTECH
	localparam CNT_100MS = 32'd2700000;
	localparam CNT_120MS = 32'd3240000;
	localparam CNT_200MS = 32'd5400000;
	`else
	// speedup for simulation
	localparam CNT_100MS = 32'd27;
	localparam CNT_120MS = 32'd32;
	localparam CNT_200MS = 32'd54;
	`endif

按照 https://stackoverflow.com/a/16745244 的回答，这个宏定义的名称应该是 MODEL_TECH ，而且 if-else 写反了，最后仿真下是正常的，但实际烧录后会无法正确复位。刚上电屏幕能正常显示，复位后就不显示了。
改为：

`ifdef MODEL_TECH

    // speedup for simulation
    localparam CNT_100MS = 32'd27;
    localparam CNT_120MS = 32'd32;
    localparam CNT_200MS = 32'd54;

`else

    localparam CNT_100MS = 32'd2700000;
    localparam CNT_120MS = 32'd3240000;
    localparam CNT_200MS = 32'd5400000;

`endif

然后测试正常。

Provide TangNano 9k board information for icestudio

Please provide TangNano 9k board information to the icestudio project, so it can be used to develop.

What are the pin numbers for the two buttons on Tang Nano 9K?

I am unable to figure out the pin numbers for the two buttons on the Tang Nano 9K board based on the pinout diagram at https://wiki.sipeed.com/hardware/en/tang/Tang-Nano-9K/Nano-9K.html

Does anyone know what those would be?

(btw that pinout diagram also does not list the LED numbers, although those can be found at

picotiny example doesn't show up via HDMI capture

Hi,

I have successfully flashed the picotiny example to the Tang Nano 9K and it works on my LCD monitor via HDMI. However, when I connect it to a HDMI capture device, the HDMI video is not detected. I have tried the Elgato Cam Link 4K as well as a generic USB HDMI capture device that you can buy on ebay/aliexpress: https://www.adafruit.com/product/4669 - in both cases I just get a black screen, and the status LED on the Cam Link indicates that there is no HDMI detected.

I have previously used these capture devices with the ULX3S ECP5-based dev kit, so I know they work with some form of HDMI from FPGAs.

Has this example been tested on a HDMI capture device? I also tried the Martoni HdmiCore code, but it gives the same result: Martoni/HdmiCore#7

I try to port from tang nano 4k but it is'not working for this board

[picotiny] Flashing got stuck at `Flashing 1/3`.

Hello, I am new to Tang Nano and I would like to try some examples on it.

I have followed every step in https://wiki.sipeed.com/hardware/zh/tang/Tang-Nano-9K/examples/picorv.html. And when I tried to download the firmware onto the flash, the program got stuck at Flashing 1/3

How to use with Mac?

I'm stuck at the Gowin part which does not seem to run on Mac

ATM I'm looking at how to run Gowin in Docker Ubuntu or in the cloud with port forwarding - if you have any instructions on how to do so?
