Currently we are integrating the serial and BLE DFU into a single binary executable. The project enables the logging (NRF_LOG_ENABLED = 1) and we use RTT as backend.
When the software starts, when ble_stack_init is called which in turn calls nrf_dfu_mbr_init_sd, we run into hardfault when sd_mbr_command is executed.
The linker file for the bootloader project is below. We had to change the start addresses when we enabled the logging. Any idea what could possibly be wrong?
