Hello, friends, my firmware version number was 2.16. When I uploaded firmware to my VESC4 using STM32 ST-Link Utility software, USB could not be recognized by my computer. It was recognized before upgrading. Before uploading firmware, I performed a full erase. The chip address in the software was 0x8000000, size: 0x31. 5cc, 32bit data width, other default settings, I do not know how to solve this problem, can someone help me? the hardware version is VESC4.11.thank you!
I use the same HW and it is working for me... make sure you update bootloader too, not only FW...
Thank you. I've found the problem. My hardware is broken.
