Hi,
I have been working through the examples for DFU with the nrf52832 dev kits from the SDK (nRF5_SDK_15.0.0_a53641a) from this folder:
...\nRF5_SDK_15.0.0_a53641a\examples\dfu\secure_dfu_test_images\uart\
My approach is to use nRFgo studio to upload the soft device and bootloader then try to load the firmware over the uart using nrfutil.
Taking the steps as follows:
1. Using nRFgo Studio: Program Softdevice : softdevice_s132.hex
2. Using nRFgo Studio: Program Bootloader: bootloader_secure_uart_debug_without_bonds_mbr.hex
3. Using nrfutil to load the application as in image below:
I have reached an impasse. I get an error message as you can see:
pc_ble_driver_py.exceptions.NordicSemiException: No ping response after opening COM port
I have checked the uart with the peripheral demo and this seems to be ok. I have also tried this with the nrf52840 dev kit too and get exactly the same result so I guess my approach is wrong somewhere.
Has anyone experienced similar? Any advice about how to proceed would be appreciated.
Thanks in advance,
Steve.
