Tang Nano 20K is a development board, using the [GW2AR-18 QN88] FPGA, containing 20736 LUT4 logic cells and 15552 Filp-Flops.
Dertails can see；https://wiki.sipeed.com/hardware/en/tang/tang-nano-20k/nano-20k.html

I am herer to ask when will Tang Nano 20K be suuported .
Thaks~

My VSCodium is configured to automatically save files. However, when invoking FPGA Toolchain > Run Testbench, modified files remain modified (bright dot shows in tab at the x location), so it will run the wrong files.

IDE Visual Studio Code(1.87) w/ platformIO and the yosys extension
As I was getting some code to pass formal verification with 'sby', the visual code "update complete" notification popped up.
my IDE was updated to v1.88.
the next time I ran 'sby', I received an error code

SBY 22:04:02 [counter] base: starting process "cd counter/src& yosys -ql ../model/design.log ../model/design.ys"
SBY 22:04:02 [counter] base: finished (returncode=3221225781)

After restarting my pc, reinstalling visual code(1.87), platformio, oss-cad-suite, the error was still the only output I could get. even running sby -E did not help.

Running :\oss-cad-suite\enviroment.bat did not change is problem. But
running :\oss-cad-suite\start.bat from the 'visual studio' terminal, got me back up and running.
I have no idea what is going on, now if I start visual code, it starts yosys.exe which quickly consume all memory and page resources on my pc (32gig)
One thing I have noticed, after uninstalling, then installing the IDE, none of the extensions where removed. I had to do that manually.
The current working dir was also saved, opening back up when I started visual code after the fresh install.
yosys.exe 100% cpu and 100% memory. on starting visual code.
I managed to close the folder, then visual code, then 'task end' yosys.exe.
But now if I open any folder containing *.v files, yosys.exe starts up and consumes all the ram and cpu

Hi,

After setting the toochain as described here
I am trying the build the uart example here

I am getting

I am not sure what might I have been missing, I know I have installed node.js which has installed the latest python 311 on my system.

Is that a python compatibility issue? If so, how can I use a different python along the FPGA toolchain?

WIll appreciate your help,
Thanks

Several demo's have "nextPnrGowinOptions": ["--enable-globals"] set in thevtangnano9k-series-examples\cpu\cpu.lushay.json
which fails saying

Finished Synthesys
Starting PnR with NextPnR
Error: unrecognised option '--enable-globals'
Finished PnR
Task finished with errors exiting
Toolchain Completed

Is there any plans on extending support to Tang Nano 20K?
