I followed all online guides Wiki. I tried to flash the SPI. I arrived to the point where the maskroom is well recognized by the computer (Linuxmint). After that I tried to flash it and the error code is that the write operation is impossible.
Unable to write the spi. The maskrom mode is tested. I mean that the maskrom mode is ok. But when the PC (Linuxmint) in sudo mode tryes to write the SPI the process fail. So my board is unusable.
