Problem with the low cost stlink programmer.. Use a genuine one may avoid most problems.. I compare the two files (before upload and the one in the MCU)...both are not same...but it worked for me...repeat the program session 2 or 3 times....it will ok...may be problem with buffers

  • How does it not work?

  • Are the battery info visible on the instrument cluster?

    • If not, the bridge itself might be broken
  • Any fault codes active on Leafspy?

Used already paired car Even initially not worked, it was worked after some programmed tries

Any way to check successfulness program over can bus messages?

maheshsachintha commented 10 months ago

I have programmed 8 number of can bridges. And compare srec file using STM32 ST-Utility. Got comparison (same) error as following. Still I haven’t plug this to car. I ll put update once I have checked with car

Any way to check this, without plugging to car

@maheshsachintha Flashing should only be done with BridgeFlasher.exe, not with STM32 ST-Link Utility. The diff is due to the copy protection still being present (au8_lock)

You did not explain how the vehicle did not work. Please only flash with BridgeFlasher.exe, and provide the following info:

Leaf 2012, 24kwh upgrade to 30Kwh. Experienced error message no at link connected.. Cable was correctly installed. Also had to disable read out protection. Still didn't flash. After upgrade st link with new software it's worked... Just in case other struggling. Never done this earlier. Now I'll try connect it in the car, believe it will work even I have not changed battery? 20240222_215921 20240222_214932 20240222_214924 20240222_220144 20240222_220201 20240222_220535

Battery swop done, been working fine for a few weeks. Guess only drawback is the battery indicator and guess'o meter are working differently... Happy with 30Kwh an extended life for our 2012 Leaf.

All you need to know are described in this forum. Just read.

Closing this, since it is not an issue with the code
