9XR stopped talking to my AVRISPmkII after uploading firmware
Posted: Sun Aug 13, 2017 9:04 pm
Yesterday i decided to try the openTX firmware on my old 9XR Transmitter. I used my AVRISPmkII and everything wen well. I backed up the existing eeprom and flashed the transmitter with the latest version of opentx. The transmitter works with the new firmware but by mistake i selected the wrong transmitter mode.
The problem is that now i can't communicate with the transmitter anymore. I get this error:
/usr/local/bin/avrdude -c avrispmkII -p m64 -P usb -U flash:r:/Users/magnus/Downloads/fgh.bin:r
=================================================================================
avrdude: stk500v2_command(): command failed
avrdude: stk500v2_program_enable(): bad AVRISPmkII connection status: Unknown status 0x00
avrdude: initialization failed, rc=-1
Double check connections and try again, or use -F to override
this check.
avrdude done. Thank you.
=================================================================================
I tried using AVR Studio but i get the same type of error. I also uploaded the latest firmware to the programmer, but that did not make anything better.
My only guess is that i somehow messed up the fuses in the ATMega 64.
The radio resets when i try to up or download to it so some communication takes place. The radio works, but it expects the throttle on the right stick so it is a bit annoying to use.
Any ideas what to do?
