STM32-H152 + ARM-USB-OCD-H + IAR problem

[dim_grig]

Hi!
Im using STM32-H152 with ARM-USB-OCD-H.
I make the connection and receive available hardware breakpoints in command promt


cd C:\OpenOCD-OLIMEX-WINDOWS\openocd-0.9.0-rc1\bin
C:\OpenOCD-OLIMEX-WINDOWS\openocd-0.9.0-rc1\bin>openocd.exe -f ./interface/ftdi/

Than I open Demo software Blinking LED in IAR (for ARM 7.50.2)... Use IAR built-in CMSIS in Project-options-General Options-Library Configuration... Choose GDB Server in Debugger and set localhost, 3333... Check Memory Regions in Linker (128kB ROM from 0x08000000 to 0x0801FFFF and RAM from 0x20000000 to 0x20003FFF)
After building I try Download and Debug

Whats wrong? Please help me

It seems that the demo program that we load kills the JTAG. It leaves only SWD available.

Either use SWD interface, or boot from SRAM and erase (overwrite) the flash.

I am working on a long-term solution but for now:

- boot from the embedded SRAM instead of the flash - set the boot jumpers to the opposite positions and erase the flash without any restarts.

I highly recommend you the blog posts by this customer who details the issue and the solution: https://balau82.wordpress.com/2013/08/14/flashing-the-stm32-p152-board-with-openocd/
