Hello,

 

does anyone have firmware for MCU ideal 15.09 or 15.11 available? Or newer?

 

I am solving a problem with communication with BMS 😞

    Aaaaa

     I found out that the newer revision of the axpert king rack already has a board with GD32 (ie 16-501444-00G)

     

    so the firmware should be 115.9+ ... then I loaded 112.22 into the MCU and checked if it somehow works....

    Unfortunately fault code 09 is usually a sign of a serious hardware problem, like many blown MOSFETs.

    Was there a loud bang? Burning epoxy smell?

    I hope I'm misunderstanding.
