I adjusted the RAM_START as below:

The Application size 112536 byes as indicated on bootloader setting. Assumed 114k or 0x1C800

Therefore RAM_START = 0x20020000 - 0x1C800 = 0x200003800 (I am not entirely sure if this method of arriving at RAM_START value is correct)

The debug output suggested new values for RAM_START and RAM_SIZE

<info> app:

After changing the RAM_START and RAM_SIZE I was able to proceed. Thanks for the help.

Sigurd,

Thanks for the reply. I was struggling to get debug output inspite of enabling NRF_LOG_ENABLE and NRF_LOG_BACKEND_RTT. I had to flash the board first then 'Attach Debugger` to make it work.

Here is the debug output:

<info> app: Kosha Device main()
<info> app: <app> info : Reset Status 2 

<info> app: Setting vector table to bootloader: 0x00078000
<info> app: Setting vector table to main app: 0x0001C000
<debug> app: ble dfu service interupts enabled
<info> app_timer: RTC: initialized.
<debug> app: timer initialised
<debug> app: power management initialised
<debug> app: Got RAM Start address
<warning> nrf_sdh_ble: Insufficient RAM allocated for the SoftDevice.
2608 to 0x20002638.
C8.

<error> app: End of error report

I am reading this tutorial to see how I can make adjustments to RAM

Hi,

Have you tried debugging your project, and see where it fails?

See e.g. this video on how to debug: https://www.youtube.com/watch?v=uP8RYgYGRvI&ab_channel=NordicSemiconductor
