HI @lushaylabs ,

I am testing the uart example on the Tang Nano 9K , when I program the devices all led goes oOn but using terminal serial port does not seems to change any of them. I am selecting the only COM port that ios connected when I turn on the board, so COM pot should not be the problem, I have tested using the VSC Serial Console with same result. What others things can I try to check?

Thank you in advance for your comments,

Please add the tags fpga, tangnano9k and maybe more to this repository, so it easier can be found.

i can run this demos on tang nano 20k as is ?

Using the lushaylabs example below. I believe the flash.lushay.json file to configure the external flash on the Tang Nano 9k only goes to the first 16kB. I have created code to load a 383kB bmp file, but after the first 16kB, values are all FF (the default for the flash chip) so my image is only partially loaded. Is there a way to expand the .json or the openFPGAloader to write to end of file so all bytes are pushed to the flash?

My .json file loads a 383kB bmp

{
"name": "flash",
"externalFlashFiles": ["test.bmp"]
}

I think
testMemory[10] = " ";

should be
testMemory[11] = " ";

Having issues with this part:

"'''
If you ever want to uninstall this driver and go back to the default driver (for example to use the official gowin IDE) all you have to do is go to "Device Manager" select the device called "JTAG Debugger" under "Universal Serial Bus devices" right-click on it and press "uninstall device" from the popup also select the checkbox to attempt to remove the driver. Once removed right click on any item in the device manager window and press "Scan for hardware changes" this should reconnect the device back with the original driver.
""""

After I tried to use GOWIN software again after reinstalling and erasing drivers I get an error when try to program.
"Cable open failed."

I believe it is due to reinstalling and deleting drivers with Zadig.

Is there a way to reset the board to factory settings? Has anyone had similar problem?
It seems like now there is something written in the board. I tried to program it with different verliog in VS code framework. And it seems like they were somehow written on it together, since the behaviour of blinking is now a mix of two codes.

I can't erase it or get it to the initial state.

Please, help.
