I am happy to hear that you now are able to resolve the issue! :)

You can change the RAM size by changing the Section Placement Macros found in the Linker tab of the Common configuration options (same options where you added the DEBUG define in your Preprocessor tab).
If you change your loggers default debug level to 4, and change the nrf_sdh_ble log level in the sd_config.h - NRF_SDH_BLE_LOG_LEVEL - to 4, then it will print out in the logger the appropriate value you should change your SoftDevice RAM start to, along with the NRF_ERROR_NO_MEM error message.

Please do not hesitate to open a new ticket if you should encounter any issues or questions in the future.

Good luck with your development!

Best regards,
Karl

When an error report is posted, you can look at the function on the line specified in the report. From the error message above, you see that the error was triggered on line 792 of main.c.
What function returned the NRF_ERROR_NO_MEM on this line?
The next thing we do is to check the API Reference for this function, to see why it would return the NRF_ERROR_NO_MEM, and then fix this issue. As an example, if the error was returned from a call to sd_ble_enable we could see the following in its API Reference:

NRF_ERROR_NO_MEM

One or more of the following is true:

The amount of memory assigned to the SoftDevice by *p_app_ram_base is not large enough to fit this configuration's memory requirement. Check *p_app_ram_base and set the start address of the application RAM region accordingly.
Dynamic part of the SoftDevice RAM region is larger then 64 kB which is currently not supported.

We would then know what to check and fix, to resolve this error.

Keep in mind that I do not have your code, so I do not know what is on your line 792, you will need to check this yourself.

Best regards,
Karl

Hello manikandan v,

Please see the suggestions by me and @awneil in your other ticket: https://devzone.nordicsemi.com/f/nordic-q-a/73304/regarding-spi-communication
The methods we suggest here - using the debugger to step through the code, and defining DEBUG to have the logger print detailed error messages - are two of the most common and successful ways of debugging your code.
Let us continue this general debugging issue in the other ticket.

Best regards,
Karl
