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

[<jia...@by...>]

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
