Assuming it's this [1]: > openocd -f board/stm32f4discovery.cfg -c "program output/STM-test8.bin > verify reset" This is obviously wrong as you flash a binary without specifying the offset, and it is 0 by default, so you get > Warn : no flash bank found for address 0 The correct offset would be 0x08000000 in this case. > Warn : STM32 flash size failed, probe inaccurate - assuming 1024k flash > Info : flash size = 1024kbytes > Error: stm32x device protected > Error: failed erasing sectors 0 to 0 This likely means you need to run > stm32f4x unlock 0 once, and if that doesn't help, > stm32f4x mass_erase 0 And then power-cycle. If it works, you'll be able to use "program" as usual as many times as you want, without these additional tricks. I recommend sticking to elf because openocd knows how to properly parse them, and uses correct offset automatically.
