button_less DFU SDK13

cedric

Hello, I'm trying the bootlader of SDK13.1, with SD S132_nrf52_4.0.2 I manage to send a ZIP file to the bootloader, but the application doesn't launch. I've tested with buttonless example, but the advertising is still dfuTarg. There must be something I've missed, but I don't know what. I someone could help me... Thanks

    Are you able to debug the bootloader? Does it reach the nrf_bootloader_app_start(MAIN_APPLICATION_START_ADDR) statement in nrf_dfu_init() in nrf_dfu.c? If so then it should branch to the application and you should be able to debug the application. Please verify that you do not end up in the app_error_handler().

    hi, to debug the bootloader, i've enabled the nrf_log module, include the several required librairies and paths to include files, and finally add uart support and nrf_log_backend support in sdkconfig.h.

    As the target file was too big for the bootloader allocated memory, I've rised it to 0xD000. But no message on debug window...

    I just gave up this solution to classic debug to see that indeed, the bootloader app start stuck. I then erase the entire chip by means of a real Jlink-Pro and Jflash and not nrfgostudio. I programmed the softdevice with nrfgostudio then the booloader.

    Then it worked...

    I managed to programm the buttonless app. I guess this problem is solved.

    Nevertheless my old application that work without bootloader doesn't work with it, and I have to erase the chip, reprogram softdevice and so on at every test... I've changed the memory footprint to fit bootloader behaviour. Everyday has its problem :/
