clock issue in FreeRTOS integration with Mesh code

It seems to work by calling

nrf_drv_clock_init();

run FreeRTOS scheduler

nrf_sdh_enable_request();

Thank you for your help

Hi Malki,

Do you use nrf_sdh module to enable softdevice and handle softdevice request ? The nrf_clock module is designed with relation with nrf_sdh module.I would suggest to enable softdevice you use the nrf_sdh module instead of using mesh_softdevice_init.c

You can refer and test with my example here (I use nrf_sdh in that example instead of mesh_sottdevice_init.c)

Please let me know if it works for you.

I tested this on the light switch provisionner and added nrf_drv_clock_init(); before the soft device init function, so the code looks like below but still I got the same error in sd_softdevice_enable()

I still ge the same error 0x1001 in sd_softdevice_enable()

    ret_code_t err_code = nrf_drv_clock_init();
    APP_ERROR_CHECK(err_code);

    /* Mesh Init */
    nrf_clock_lf_cfg_t lfc_cfg = DEV_BOARD_LF_CLK_CFG;
    ERROR_CHECK(mesh_softdevice_init(lfc_cfg));
    mesh_init();

Could you clarify, you haven't start any FreeRTOS code and you have the issue ? If it's the case, i would suggest to check with our default application and see why it didn't work in your case.

The NRFX_CLOCK_CONFIG_IRQ_PRIORITY is set to 7.

I init the clock and the softdevice before FreeRTOS

I tried calling nrf_drv_clock_init() and then sd_softdevice_enable() but I get the same error. Is that normal ?

Hi,

I suspect you got that error because the call nrfx_clock_enable() will enable the LFCLK interrupt and with high priority that not allowed by the softdevice. You should check NRFX_CLOCK_CONFIG_IRQ_PRIORITY in sdk_config.h, it should be at 7.

Another suggestion is to call sd_softdevice_enable() (or nrf_sdh_enable_request) before initialize FREERTOS.

I actually don't have much experience with FreeRTOS, so not really sure if FreeRTOS need to be initialized before the softdevice or not.
