Re: [OpenOCD-user] 答复: need help for program multiple devices in daisy chain

Thanks again Paul.

I finally find why my first script didn't work.

"reset" command just make "targets" to default. So if "targets" before a
"reset", it may be useless to switch the current target.

So this won't work correctly:

targets stm32f217.cpu

init

reset init

flash write_image erase unlock "mcu1_pb6_slow.hex"

targets stm32f302.cpu

flash write_image erase unlock "mcu2_pb11_slow.hex"

reset

shutdown

Indeed, sorry, haven't noticed that. I would expect "flash write_image" to
complain when it tries to flash a non-halted target though.

 

The usual scenario is using "reset init" just before flashing, so I would
expect your script to be something like this:

 

init

reset init

targets stm32f217.cpu

flash write_image erase unlock "mcu1_pb6_slow.hex"

targets stm32f302.cpu

flash write_image erase unlock "mcu2_pb11_slow.hex"

reset

shutdown
