Soft device enable causes a Hard Fault

[LSz]

Hello,

I am developing an application using

1. SEGGER Embedded Studio.

2. SDK 17.0.2.

3. Cortex-M nrf 52840.

Recently I changed the OS from FreeRTOS to embOS and now I have a Hard fault that is caused by :

SVCALL(SD_SOFTDEVICE_ENABLE, uint32_t, sd_softdevice_enable(nrf_clock_lf_cfg_t const * p_clock_lf_cfg, nrf_fault_handler_t fault_handler));

I understand that I have a problem enabling the softdevice, the Hard fault information is: 

00> [00:00:00.002] <unknown> HARD FAULT at 0xFF29FFFA
00> [00:00:00.002] <unknown> R0: 0x00000000 R1: 0x00000000 R2: 0x00000000 R3: 0x2001CFD0
00> [00:00:00.002] <unknown> R12: 0x2001DA7C LR: 0xFF29FFFA PSR: 0x6000000B
00> [00:00:00.002] <unknown> Cause: The processor has attempted to execute an undefined instruction.

Hi,

Unfortunately, we do not support embOS. I would recommend trying seggers support for embOS issue.

In general I would say you should make sure you do not violate the Softdevice System on Chip resource requirements and also that you make sure you understand and follow the Softdevice Interrupt model and processor availability
