  • Problem with reprogramming STM32 using J-Link with IAR Workbench V5.1

    I have been successfully debugging a board with an STM32 Cortex M3 processor using J-Link with IAR for ARM V5.1 but today, it suddenly failed to load the Flash Loader and, despite resetting everything, I cannot erase or reprogram the device. I have tried to use the demo version of J-Flash but it cannot see the STM32 on my board. Do you have any means of erasing the device?

    EDIT: I should add that I am using JTAG for the debug link and that the same thing has just happened on a second board which I started to use after writing this post; this board programmed fine the first time then, using the same code locked up.

    Here is the Debug Log:

  • bad code

    It seems that you loaded a bad code in your boards. So to recover them you need to boot from RAM(if i's possible) then load any working example.
    With the latest version of EWARM5.20, you don't need to boot from RAM, you need just to setup the Reset type to core and peripherals and it will work fine.
