I have an issue with my tangNano board.
With gowin programmer (gui) or programmer_cli for all command (read user code, flash SRAM, flash embFlash, …) the tool stop with the message:
Error: VLD Down!
I have no idea of the reason why this message is displayed, the only one reference to VLD is TN653 (JTAG) and no options in programmer seems to allows to revert for a correct state.
Someone could help me to fix this?
