I want to use rpll by IP generator but it doesn’t show the unit of frequency if it is KHz or MHz?

Hi, how to use the 2.4GHz antenna on the Dock board

Hello, I`m a FPGA/VHDL Learner.

Question: Is there any place where we can add / check examples / community projects ? There is an example Github repo but I believe a lot of people have their own repos and It would be great if we could prepare some list of that stuff.

Colpocorto commented 10 months ago

I don't see any COM port or converter device. I've installed the provided driver manually on Windows 10 but it does not work.

Hi, the only clock reference is the externel 27MHz cristal oscillator? or the FPGA has other higher frequency reference clock. If so, how to use it? I mean, if in the Blink example I would like another clock reference than the 27MHZ, there is another option?

Test with a fully loaded USB cable. You are most likely using a charger style USB cable only which is missing the required D+ / D- lines for communication over USB. A fully loaded USB cable will offer all such conductors.

Probably late for your question but suggest to learn Verilog which is easier to digest. Review the great websites by lushaylabs.com and also fpga4fun.com. Each offers a wealth of knowledge on Verilog.

Hi, After programming .fs file device gw2ar (tang 20k) is not found in programmer. Is there the way to factory reset, or erase? Thanks.

juthi commented 5 months ago

From my recollection, the target FPGA is SRAM based so it is only alive while you are powering the device. So attempt to power down and test again but next time, mask off the port pins used by JTAG.

serperus commented 5 months ago

Used as exflash and erased thru gao. Erased it with pressing s2 button while powering up, then reprogramed again. Now it is alive.

hi, i flashed a program on the 25k and is working but when i try to download another code it says not gowin device foung, and i tried everything and nothing work, i cant even delete the code on

serperus commented 3 months ago

hi, try to power it on with s1 button pressed.

I've just got the Tang Nano 20K, how do I connect to the serial in LiteX under Linux (NOT Windows)? screen /dev/ttyUSB0 115200 (and 9600) does not work, I get weird symbols sent back.

Never mind, it was /dev/ttyUSB1, and you have to start screen not long after plugging in the USB cable to see the boot text that Sipeed shows in their wiki.

devom1626 commented 1 month ago

Hi too late, i already found the error, thank

Hi Team, I need a MCU GMD tool Version 1.1, currently i am using 1.2GMD. Gowin Vendor engineer saying 1.2V is not compitable with GW2AR-18LV board.so please so send me the link where i can downlod 1.1V GMD

Yes, see section 1.7 here:

https://wiki.sipeed.com/hardware/en/tang/Tang-Nano-Doc/questions.html i only find the programmer version 1.9.9.03, is ok?

i have the same error ![Uploading error.png…]()

juthi commented 1 week ago

The corrupt firmware is stored inside the external flash device. Only if you feel comfortable and have the tools, you could remove the external flash which will then fail to load the corrupt firmware. Alternate ideas are to manually corrupt the data from this flash upon power up but this implies to force the I/O pins on the external flash to ground or similar. This will alter the firmware that is being booted. Do wait on other comments.
