use arm-none-eabi-addr2line.exe to find the line in the code that matches the address. If you a bus fault, fault_pc may tell you where the illegal access was. You can then perhaps see where the problem happen. Hopefully then you can attach and check the value in last_line. If something else, jump to a safe while loop. Uint32_t last_line _attribute_ ((section (“.noinit”))) ĪT the begining of the code check if the reset is due to a normal power up or something else. A trick I’ve used in the past is to put a variable in the no init section in ram. Being overloaded with too many stuff, with rarely time at night to work on new posts. PS: I apologize for being silent for a month. ? I think technically the same should be possible with the OpenOCD or GDB P&E Multilink, but I have succeeded doing this only with the GDB Server from Segger. Thanks to Liviu (the maintainer of the GNU ARM Eclipse plugins) and Segger to make this important feature work with GDB :-).
#Segger embedded studio never hits breakpoint update
With the new update and plugin I’m able to debug a crashed application and can connect to the board after the crash to find out what the status of the board is.

Or (if you can) keep the debug probe powered/attached so you do not risk an accidental reset of the board. I recommend you get some practice and experience hooking up the probe. Using the J-Link ‘Light’ version I had at least to Power the J-Link “Lite” before attaching it to the board, otherwise the board was reset by connecting the SWD/JTAG cable. I’m able to connect the J-Link (EDU) after the crash and to attach/debug it. I’m able to successfully attach and debug to my boards with the J-Link (EDU). What I recommend is to have a dedicated debug configuration (you can copy/clone an existing) only for attaching. ? Do not forget to switch that off again if you want to debug in a normal way. This update comes with an important feature: the ‘Connect to running target’ option is now available (it was grayed out and not functional in earlier versions). I had to update the GNU ARM C/C++ J-Link Debugging plugins to the version 3.02281154 (see above screenshot).

In Eclipse/KDS, use the menu Help > Install New Software and use the following update site: Verify that you have the latest GNU ARM Eclipse plugins installed. Update GNU ARM Eclipse Segger Debug Plugin That means the GDB connection shall *not* reset the target as it usually does. The goal is to be able to connect to a running target, without overwriting the application on the board (attach/connect) so the problem on the board can be inspected with the GNU GDB debugger. with J-Link debug probe or J-Link OpenSDA firmware). I’m using here Kinetis Design Studio V2.0.0, but it is applicable to any Eclipse with the GNU ARM Eclipse plugins and the Segger GDB Server (e.g.
