DFU

[Mikael]

Hi,

I use a custom board, softdevice and boot loader.

I use DFU to update a slave chip firmware. Everything goes right until we invalidate and write flash :   

        // Invalidate bank, marking completion.
        nrf_dfu_bank_invalidate(&s_dfu_settings.bank_1);

        uint32_t ret_val = nrf_dfu_settings_write_and_backup(NULL);

the nrf_dfu_settings_write_and_backup lead to a HARDFAULT handler because of accessing flash :

static inline void wait_for_flash_ready(void)
{
    while (NRF_NVMC->READY == NVMC_READY_READY_Busy) {;}
}
