    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.
