Hello,
I am trying to do a single bank DFU update using nRF Connect app and have SDK 16 on my device. I have set NRF_DFU_SINGLE_BANK_APP_UPDATES to 1. Bot looking at postvalidate (attached below) in nrf_dfu_validation.c, it automatically swicthes to Bank 1. Is there some settings that I am missing?
Thank you.
nrf_dfu_result_t postvalidate(uint32_t data_addr, uint32_t data_len, bool is_trusted)
{
nrf_dfu_result_t ret_val = NRF_DFU_RES_CODE_SUCCESS;
dfu_init_command_t const * p_init = mp_init;
if (!fw_hash_ok(p_init, data_addr, data_len))
{
ret_val = EXT_ERR(NRF_DFU_EXT_ERROR_VERIFICATION_FAILED);
}
else
{
if (p_init->type == DFU_FW_TYPE_APPLICATION)
{
if (!postvalidate_app(p_init, data_addr, data_len, is_trusted))
{
ret_val = NRF_DFU_RES_CODE_INVALID_OBJECT;
}
}
#if NRF_DFU_SUPPORTS_EXTERNAL_APP
else if (p_init->type == DFU_FW_TYPE_EXTERNAL_APPLICATION)
{
if (!is_trusted)
{
// This function must be implemented externally
ret_val = nrf_dfu_validation_post_external_app_execute(p_init, is_trusted);
}
else
{
s_dfu_settings.bank_1.bank_code = NRF_DFU_BANK_VALID_EXT_APP;
}
}
#endif // NRF_DFU_SUPPORTS_EXTERNAL_APP
else
{
bool with_sd = p_init->type & DFU_FW_TYPE_SOFTDEVICE;
bool with_bl = p_init->type & DFU_FW_TYPE_BOOTLOADER;
if (!postvalidate_sd_bl(p_init, with_sd, with_bl, data_addr, data_len, is_trusted))
{
ret_val = NRF_DFU_RES_CODE_INVALID_OBJECT;
if (is_trusted && with_sd && !DFU_REQUIRES_SOFTDEVICE &&
(data_addr == nrf_dfu_softdevice_start_address()))
{
nrf_dfu_softdevice_invalidate();

}
if (!is_trusted)
