I’m trying to upgrade a V6 card (with V0.92 fw) to the latest firmware using the AVRISP MKII programmer. My command line is like this:
avrdude -p x192a3 -c avrispv2 -b57600 -P usb -U flash:w:tinyg-master-440.20.hex
I am using the baudrate 57600 becuase 115200 got the same error and I have other projects using the same baudrate
Here is the error I get:
avrdude: stk500v2_command(): error in CMD_XPROG_SETMODE: Unknown
avrdude: stk600_xprog_program_enable(): CMD_XPROG_SETMODE(XPRG_MODE_PDI) failed
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override this check.
avrdude: stk500v2_command(): error in CMD_XPROG: Unknown
avrdude: stk600_xprog_program_disable(): XPRG_CMD_LEAVE_PROGMODE failed
avrdude done. Thank you.
Using the usb port on the tinyG just gave a Programmer failed to resond error.
Any help will be appreciated.
