However, when I tried to reflash it with our ST-link I got an error message “STm device protected”. I managed to flash the firmware successfully, and have confirmed that it works by looking at the CAN messages being sent. In procedure 'program_error' called at file "embedded:startup.I modified the CAN firmware (razoredge branch) so that error, axis state, current, and position is continuously streamed in the heartbeat message (since the position in our application we are using won’t be larger than the int16 max and min values). In procedure 'program' called at file "openocd.cfg", line 11Įrror executing event reset-init on target stm32f4x.cpu:Įmbedded:startup.tcl:449: Error: ** Programming Failed **

Also included is the openocd.cfg file. I have managed to get it to connect to the vesc (can be seen in the openocd output.txt) but it won't program due to the device being protected. From my research I found that this could perhaps be a firmware or bootloader issue so I have been trying to redo it using a raspberry pi running openocd and the GPIO pins connected to the vesc. It now only displays a blue light when on (no green like my other working vesc). I was riding my skateboard the otherday when it suddenly lost power and wouldnt reboot.
