Hi,
I am tring to write data by the FDCAN bootloader of system memory, my target is STM32H563.
Now, I can read the device ID, perform the mass erase command, but I can't write data to SRAM/Flash, the FDCAN bootloader doesn't response any CAN message after the Write_Memory command.
Below picture is the CAN message log when I try to write 64 bytes data to flash at 0x0802_0000.
I also check the 'Write_Unprotect' command, so the MCU is not write protect.
Do I miss something have to do?
Thank you.
You've told it you're writing 256 bytes but you've only sent 64. It's waiting for the rest.
