Good day,
I use a daisy chain configuration for 2 STM32 MCUs:
J Link(TDI)-->(TDI)stm32f217(TDO)-->(TDI)stm32f302(TDO)-->(TDO)J Link
I think I have set up the TAPs correctly, but the "flash write_image" always
flash the same MCU, it does not switch target.
I use the "targets" command below for switching target before flash program:
targets stm32f217.cpu
init
reset init
flash write_image erase unlock "mcu1_pb6_fast.hex"
reset run
but it failed at switching...
What's wrong here?
--------------------------
my whole board.cfg file:
# interface
interface jlink
jlink serial 304439649
# board
transport select jtag
set CHIPNAME stm32f302
source [find target/stm32f3x.cfg]
set CHIPNAME stm32f217
source [find target/stm32f2x.cfg]
reset_config none
targets stm32f217.cpu
init
reset init
flash write_image erase unlock "mcu1_pb6_fast.hex"
reset run
targets stm32f302.cpu
init
reset init
flash write_image erase unlock "mcu2_pb11_fast.hex"
reset run
shutdown

Thank you Pual, I figured it out myself, by using this command. It seems "reset" command reset all defined target as said in user manual. However, "halt" just halt current target. init targets stm32f217.cpu halt flash write_image erase unlock "mcu1_pb6_slow.hex" targets stm32f302.cpu halt flash write_image erase unlock "mcu2_pb11_slow.hex" reset run -----邮件原件----- 发件人: Paul Fertser [mailto:fer...@gm...] 发送时间: 2018年11月1日 18:33 收件人: jia...@by... 抄送: ope...@li... 主题: Re: [OpenOCD-user] need help for program multiple devices in daisy chain Hello, On Thu, Nov 01, 2018 at 11:56:32AM +0800, jia...@by... wrote: > I think I have set up the TAPs correctly, but the "flash > write_image" always flash the same MCU, it does not switch target.

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 -- Be free, use free (http://www.gnu.org/philosophy/free-sw.html) software! mailto:fer...@gm... |

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 On Thu, Nov 01, 2018 at 08:27:15PM +0800, <mailto:jia...@by...> jia...@by... wrote: > I figured it out myself, by using this command.
