I could program a attiny402 on both using avrdude. "avrdude -p t402 -c serialupdi -P /dev/cuaU0 -U flash:w:curr-mon.hex" On the amd64 machine I had to lower the baud rate from the default (115200)= to 57600, but on the RPI4 it worked at the default speed. I also tried pymcuprog (by the Microchip guys) and with the patch, it does = now get past the serial port initialization, and simple (short) commands work, = like ping and erase, but write fails. It seems that the received bytes sometimes= get delayed. Using a Prolific USB to serial dongle and the resister mod, both avrdude and pymcuprog work on the amd64 desktop and the RPI4 at the default speeds. So the D46290 patch makes the uchcom driver a lot more useful. --=20 You are receiving this mail because: You are the assignee for the bug.=
