Hello, bootlaoder communication burning. After modifying the hardware, I found that when burning the program, sometimes I found that all can messages were 0 and could not be burned. I asked if it was possible that there was a problem with the can chip or that the mcu BootLoader area was damaged, and what could be the reason for this

Hi @zhouqicheng 

this is very general description. There could be a lot of reasons for this. First step is to attach a debugger and check if the bootloader is still in place and then check where the code is hanging or what actually happened. Without this, I'm not able to help.
