LitexCNC: firmware and driver for 5A-75B and 5A-75E

I have tried usb blaster clone and ft232RL but nothing works.
Has anyone the bin fine to flash directly the flash chip with programmer Xgecu TL II plus ?

Hello, I have another question. On my V8.2 board, the two encoder inputs listed in the JSON file as " {"pin_A": "j3:5", "pin_B": "j3:6"}," seem to be connected to buffer U18. If I have only re-soldered the buffers U23, U24 and U28, as described in the example, I cannot use these two pins as encoders. Is this a special feature of my board version?

chubby75/issues they said that pinout 8.2 corresponds to version 6.0.
From the photos I can see that it looks like 8.0 (which is similar to 6.0). and U18 is on the other side...

Could you upload photos for comparison?

If this is not the case, and you have some new version of the board, then you will have to match the J-pin to FPGA-pin in the pinout table in the file \litex\litex-boards\litex_boards\platforms\colorlight_5a_75b.py"
and then edit the json according to the new direction of the buffers on your board...

Sorry, at first I thought you were talking about 75E.

But I have the same 75B-8.2
J3:5 -> U24
J3:6 -> U18
U18 is also connected to the distributed pins.
This means you won't be able to use these pins as input. (only with baypass)

Change the JSON, assign the encoder to the pins that you made as input... 

I have a ulink2 (with cmsis-dap firmware) can with this flash litexcnc bit file ?
