Hi Amey, 

asBuild target 'nrf52840_xxaa'

Are you building the nRF52840 project for nRF52833DK? It may not work on nRF52833DK. 

What example are you using? You could try examples\ble_peripheral\ble_app_uart\pca10100 for nRF52833DK or use it as the base to develop.

no i am using example of examples\ble_peripheral\ble_app_template\pca10100 for nRF52833DK, give proper solution how the error can be solved

Hi Amey, 

I think you are creating ble_app_template pca10100 for nRF52833DK.

Are you able to build the unmodified ble_app_template pca10056 without those issues?  Which version of nRF_DeviceFamilyPack are you using? Could you try v8.35?

I duplicated the ble_app_template pca10056 and modify the Rom/Ram address and target to create the file for pca10100 for nRF52833DK as  7725.pca10100.zip. Please place under nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral\ble_app_template and build with nRF_DeviceFamilyPack v8.35.

Hi, amanda

Could you please explain why this phenomenon occurs?
I'm getting a similar error in my environment.
It happened when I set it not to use microlib.
