How to get the default firmware back on the I2C Adapter
b0rna 2014-04-02 21:39:18 7662 Views2 Replies After flashing a modified source (without any success), and seemingly bricking the 644PA on the adapter, I backtracked my steps to try and get it up and running again.
I used an Arduino UNO to successfully:
1 - Flash the optiboot 644P bootloader back on the adapter
2 - Compile the original V1 source, from the github repo and use the ISP again to successfully load it on to the adapter
I can see intermittent flashes of the indicator LEDs attache to the STM/CAN micro, which is a good sign, as they were absent while in a bricked state. However, I cant seem to get and OBD2 functionality back onto the MEGA logger/shield?
Has anyone successfully compiled and gotten default functionality with this adapter before?
I think that most likely, either I have the wrong bootloader, or that I am not configuring the source properly.
Edit: where can I obtain the original bootloader from?
Thanks in advanced.

2014-04-12 17:37:47 Sorry if I've misunderstood something,
So what you are saying is that, although there is a guide with flashing instructions and provided source code, users are actually not suppose to or encouraged to follow them for development?
What I was referring to was making light modifications to the firmware of the 644PA.
I can already successfully flash compiled sources via both of the methods (ArduinoISP and USBASP).
Or are you implying that the source code for this unit is not provided, and that significant changes are required to be made to the posted firmware and firmware_v2 sources in order to obtain original functionality?
Thank you. b0rna

b0rna 2014-04-11 23:04:40 I've purchased a USBASB programmer which avoids the bootloader.
I still can't get default functionality with the posted source even using the arduino builder and/or codeblocks.
Any help Would be appreciated.
Thanks. b0rna
