Warning : Stack pointer is setup to incorrect alignment. Stack Addr = 0xFFFFFFFF

[Tig]

Dear sir,

Hope you are doing well.

I am trying to debug my project using the IAR toolchain. I am using nRF 52832. In my project, I have added dfu init service for performing OTA. 

Now I want to debug my project using IAR toolchain. For that, I have commented the DFU portion for debugging. While debugging I am getting the error of "Stack pointer is setup to incorrect path. Stack Addr = 0xFFFFFFFF". I am using Jlink for compilation.

Any help would be appreciated.

Thanks

Here's a tip for IAR if you haven't come across this before; debugging when (eventually) running the SoftDevice is not easy unless the SoftDevice interrupts are allowed to run during a breakpoint halt. Not sure about DFU without SoftDevice.

#if defined(SOFTDEVICE_PRESENT)
   // This allows all interrupts higher than _PRIO_SD_LOW (ie 4, BLE SD stuff) to continue execution even during a break
   // note Two J-Link commands are required in command file:
   // SetMonModeDebug = 1
   // SetMonModeVTableAddr = ADDR
   //  where ADDR is the application's vector table located in FLASH, ie the start address for the
   // application, probably either 0x1B000 or 0x1C000 or 0x26000 depending on SoftDevice
   // See https://github.com/NordicPlayground/j-link-monitoring-mode-debugging
   NVIC_SetPriority(DebugMonitor_IRQn, _PRIO_SD_LOW);
#endif

Ensure JLinkMonitor subdirectory is enabled in the project (not greyed out)
When finished debugging, in the BLE project settings under Options->Common->Debug->Set Addional J-Link Options
SetMonModeDebug = 0
Depending on your J-Link and licence there is an irritating message pop-up at the start of very debug session; this is why we usually leave SetMonModeDebug = 0
Do not use this for non-BLE projects.
