hatdfault BLE application on srf52833 with s140 softdevice

[Davide Renzetti]

Hello,
I'm trying to use BLE on nrf52833. I'm developping with segger embedded studio and I' m usign the BLE peripheral example "ble_app_blinky".
Firstly I erased the flash memory and installed the softdevice:

nrfjprog --eraseall
nrfjprog --program s140_nrf52_7.2.0_softdevice.hex --verify

Then I compiled the application and debugged. When the application go to sd_softdevice_enable, the system go to hardfault!

The linker setup is:
FLASH_PH_START=0x27000
FLASH_PH_SIZE=0x59000
RAM_PH_START=0x20002C00
RAM_NOINIT_SIZE=0x3000
RAM_PH_SIZE=0x1d400
FLASH_START=0x27000
FLASH_SIZE=0xa59000
RAM_START=0x20000000
RAM_SIZE=0x20000
DEFAULT_CONFIG_START=0x27000
DEFAULT_CONFIG_SIZE=0x400
FCONFIG_START=0x28000
FCONFIG_SIZE=0x1000
INIT_START=0x29100

Thank you in advance for support.

Hi Davide, 

Can you please enable the serial logs and give us some details of the hardfault on your serial logs. Also make sure you enable 

HARDFAULT_HANDLER_ENABLED to 1 in your sdk_config.h

There also an external blog you can use to try to attempt to debug the hardfault to get the context of where the hardfault happens.

Hi Susheel,

I thought it was a stack or heap size problem, so I enlarged a lot their size, but I always have hardfaut. I enabled the hardfault handler. These are the results:

HARD FAULT at 0x00000000  R0:  0x00000000  R1:  0x00000000  R2:  0x20002C00  R3:  0x200108A0
  R12: 0x00000000  LR:  0x00000000  PSR: 0x2000000B
Cause: The processor has attempted to execute an instruction that makes illegal use of the EPSR.
