HARD FAULT with P&E MULTILINK DEBUGGER

Hi,

my target is S32k311 and I'm using Q-100 eval board. recently I added some code to my project which caused a HARD FAULT trigger.

we're using P&E USB MULTILINK debugger with GDB Eclipse, ever since I added the code that caused a HARD_FAULT .the debugger does not connect and this is what I get in the console:

Initializing.
Target has been RESET and is active.

Starting reset script (C:\NXP\S32DS.3.5\eclipse\plugins\com.pemicro.debug.gdbjtag.pne.expansion_5.5.7.202304031909\win32\gdi\P&E\supportFiles_ARM\NXP\S32K3xx\S32K310.mac) ...
REM Enable clocks for selected cores in MC_ME module (the sequence below enables all clocks).
REM Initialize RAM and DMA:
REM Initialize DMA TCD:
REM Copy valid executable code to RAM for each core to be used.
REM Enable required cores in MC_ME:
Delaying for 20mS ...
Done.

Reset script (C:\NXP\S32DS.3.5\eclipse\plugins\com.pemicro.debug.gdbjtag.pne.expansion_5.5.7.202304031909\win32\gdi\P&E\supportFiles_ARM\NXP\S32K3xx\S32K310.mac) completed.

BusFault: An imprecise (asynchronous) data access error has occurred.
HardFault: A fault has been escalated to a hard fault.

I do get the same error message even when I remove the code which caused this in the first place.

recycling the power and USB connections has no effect.

I need your assistance.

Regards,

Koorosh Hajiani

Hi,

one of the common root cause could be the peripheral clock is not enabled before peripheral is accessed in code. So check this.
