Monitor mode debugging not working with IAR and s140 6.0.0-6alpha

[Chaabane]

Hello,

I followed the steps mentionned in this blog

I did all the required step but I'm still seeing the same behavior. below is my setup :

I'm using nRF52840 and s140 6.0.0-6 alpha. IAR 7.70.1 JLINK 5.22a SDK 14.0 (att_mtu_troughput) and SDK 14.2.0 (ble_app_blinky). nRF52840 dev kit board

I tried what was suggested in different questions asked before this but still not able to make it work.

-Increased the priority to 6 : NVIC_SetPriority(DebugMonitor_IRQn, 6ul). -Made sure I have DebugMon_Handler in both sides. -Removed CONFIG_GPIO_AS_PINRESET.

• Chanegd "SetMonModeVTableAddr=0x1B000" to 0x2500 the start address of the s140 6.0.0-6alpha but the breakpoints wont work at all with this setup.

Not sure what might be wrong with my setup !!

any suggestions would very appreciated.

Thank you Chaabane

I put this address (0x22000) in the macro file (It is the same address used in the linker). When proceeding as mentionned in my previous comment, the code doesn't pass by the breakpoint but goes straight to the "HardFault_Handler" ! this handler seems to be called by the Cortex-M but when checking the Hardfault error register (NVIC:CFSR) no fault flag is set which is weird !.

Any suggestions ?
