Hello,

What does your log say when this happens? I would think that you need to adjust your memory sections, if you have changed something in the SoftDevice configuration since your last build.

Please make sure to have DEBUG defined in your preprocessor defines, like shown in the included image:

This will make your logger output a detailed error message whenever a non-NRF_SUCCESS error code is passed to an APP_ERROR_CHECK.

Best regards,
Karl

Please consider these two images

Please add the DEBUG define, and enable logging. This will output exactly what you need to change in your section placement macros.

Best regards,
Karl

Added the debug but got the same error

for

error_code = nrf_sdh_enable_request();
APP_ERROR_CHECK(err_code);

for above function received error code 0x8

and for

    error_code = nrf_sdh_ble_enable(&ram_start);
    APP_ERROR_CHECK(err_code);

for above function received error code 0x4

[Karl Ylvisaker]

What does your log say exactly, when these error codes are returned?
Please share the full log with me, for both cases.

There is no way for me to provide you with the necessary changes to the section macros without these error messages, or without seeing your complete project.

Best regards,
Karl

Hi
I have changed the RAM_START to 0x20003F08
and both issue have been resolved
Thanks for help!!!

I believe I'm struggling with the exact same issue, how did you get the full log? I only receive the same logging as your previous message.
