Hello all
currently I am flashing the device using command line:
#erase chip
nrfjprog --family NRF52 --recover
#program softdevice
nrfjprog --family NRF52 --program .\firmware-img\s132_nrf52_6.1.1_softdevice.hex --chiperase
#program bootloader
nrfjprog --family NRF52 --program ..\nRF5_SDK_15.2.0_9412b96\examples\dfu\secure_bootloader\pca10040_ble\ses\Output\Release\Exe\secure_bootloader_ble_s132_pca10040.hex
#program software
nrfjprog --family NRF52 --program .\Project-nRF52832\Output\Debug\Exe\BLE-nRF52832.hex
#reset chip
nrfjprog.exe --family NRF52 --reset
software uploads, but FOTA process fails
however, if after that process I flash the application software only via JTAG, then power board on\off, and then performing FOTA all works fine
this is the output while flashing using segger (notice content already match so no software is being downloaded):, please advice
