Dear All.
I'm using nRF52840 DK, 15.3.0 SoftDevice, Segger.
I'm testing DFU and have some question. and i'm begginer with all
I'm so sorry in advance.
First.
I flashed example "ble_app_buttonless_dfu" but it crashed with "no bootloader found" and it's not advertising.
I noticed that the problem is literally the boot loader doesn't exist. am i right?
Am I doing wrong with this ble_app_buttonless_dfu?
Second.
So I tried another method to use DFU.
I flashed "sd_s140_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_with_bonds.hex" with nRFgo
but It said "programming failed : Verification failed". like below
So I tried to flash it with nRF Connect.
then it said to me a lot of things are going to wrong like below
how do I flash it and watch its advertising?
Third.
I have also nRF52832 which is custom board that I didn't design
In this board, the "sd_s132_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_with_bonds.hex" with nRFgo is flashed well
but not advertising, I thinks it didn't work becase the some clock config things
I usually use this board with this code(some clock config)
so, the question is can i make some change with the "sd_s132_bootloader_buttonless_with_setting_page_dfu_secure_ble_debug_with_bonds.hex"
to config the clock things to see its advertising.
if I am doing wrong, please let me know how i use this buttonless dfu example.
thanks.
best regard.
