rtos - softdevice with nrf51422

bubune

Hi Support team,

I've ported succesfully chibios RTOS on the nrf51422 for month. I've also ported some drivers like I2C - UART - SPI- GPIOS and others... I can play with it make some apps that running perfectly.

Now I've started to integrate the softdevice but I get problems. In the main, first thing is done is to enable the softdevice.

sd_softdevice_enable(NRF_CLOCK_LFCLKSRC_XTAL_50_PPM, softdevice_assert_callback);

But soon I call this function I get hardfault handler.

I made special attention about Ram/Flash usage and other recommandations. Chip is working well as I run sucessfuly the Hrm example.

Can you list all things that I need to check that can cause this issue?

Regards, Bruno

    Well, after some deep investigations, it means we get an hardfaultt execption soon Softdevice is active when PSP stack is activated before (CONTROL reg =2). Can you confirm this behavior on NRF51422_AAC0 and SDK 4.2.2? Next step, will be activate PSP stack on the HRM ANT+ exeample. I will post later on the result.

    Regards, Bruno
