Buttonless DFU not flashing new firmware SDK 15.2.0

nem22

Hello,

We are trying to get DFU to work on our custom board running nrf52832. It has previously worked on the devkit. Our board does not have a crystal so we are using NRF_CLOCK_LF_SRC_RC both in the bootloader and application. Our bootloader is based on the example secure_bootloader_ble_s132_pca10040, the only changes we made are led/button behavior, public key and enabled rtt logging for debugging.

We are testing the DFU functionality using nrf connect for android.

The bootloader receives the signed zip but does not flash it. Below are some errors from the log (Flash write/erase failed (0x3))

What could be causing those errors? I've also attached a more full log.

Thanks

    Hi Nem22, 

    are you able to reproduce this on a nRF52 DK? If so then I would be great if you could share the project  + dfu images so that I could debug it. 

    I am not seeing any "Could not erase the settings page!" or "Could not write the DFU settings page!" statements in the log output, which I would expect when nrf_fstorage_write() and nrf_fstorage_erase() are returning NRF_ERROR_INTERNAL. Could you setup breakpoints in settings_write() in nrf_dfu_settings.c and see why this is not caught? 

    static ret_code_t settings_write(void                   * p_dst,
                                 void const             * p_src,
                                 nrf_dfu_flash_callback_t callback,
                                 nrf_dfu_settings_t     * p_dfu_settings_buffer)
{
    ret_code_t err_code;

    if (memcmp(p_dst, p_src, sizeof(nrf_dfu_settings_t)) == 0)
    {
        NRF_LOG_DEBUG("Destination settings are identical to source, write not needed. Skipping.");
        if (callback != NULL)
        {
            callback(NULL);
        }
        return NRF_SUCCESS;
    }

    if (NRF_DFU_SETTINGS_IN_APP && !settings_forbidden_parts_equal_to_backup((uint8_t *)&s_dfu_settings))
    {
        NRF_LOG_WARNING("Settings write aborted since it tries writing to forbidden settings.");
        // Assuming NRF_DFU_SETTINGS_ALLOW_UPDATE_FROM_APP is configured the same as in bootloader.
        return NRF_ERROR_FORBIDDEN;
    }

    NRF_LOG_DEBUG("Writing settings...");
    NRF_LOG_DEBUG("Erasing old settings at: 0x%08x", p_dst);

    // Not setting the callback function because ERASE is required before STORE
    // Only report completion on successful STORE.
    err_code = nrf_dfu_flash_erase((uint32_t)p_dst, 1, NULL);

    if (err_code != NRF_SUCCESS)
    {
        NRF_LOG_ERROR("Could not erase the settings page!");
        return NRF_ERROR_INTERNAL;
    }

    ASSERT(p_dfu_settings_buffer != NULL);
    memcpy(p_dfu_settings_buffer, p_src, sizeof(nrf_dfu_settings_t));

    err_code = nrf_dfu_flash_store((uint32_t)p_dst,
                                   p_dfu_settings_buffer,
                                   sizeof(nrf_dfu_settings_t),
                                   callback);

    if (err_code != NRF_SUCCESS)
    {
        NRF_LOG_ERROR("Could not write the DFU settings page!");
        return NRF_ERROR_INTERNAL;
    }

    return NRF_SUCCESS;
}

    Best regards

    Bjørn

    Hello Bjorn,

    I have not been able to reproduce the issue on nRF52 DK, dfu works perfectly, no errors when flashing settings page.

    I added log_infos after nrf_dfu_flash_erase and nrf_dfu_flash_store and they are both returning 0 - NRF_SUCCESS

    Is there a SB or jumper on the DK I can use to confirm it's not using the crystal?

    Thanks

    Hi nem22, 

    to me that makes no sense. How can nrf_fstorage_write() and nrf_fstorage_erase() return return code 0x03, which in turn is returned by nrf_dfu_flash_erase() and nrf_dfu_flash_store() as err_code in  settings_write()? A non-zero( i.e. not NRF_SUCCESS) should be caught by the if (err_code != NRF_SUCCESS) check. Can you double check that rc in nrf_dfu_flash_store/erase is not modified between the nrf_fstorage_write/erase call and the return rc statment?

    Is there a SB or jumper on the DK I can use to confirm it's not using the crystal?

     No, the 32kHz crystal is connected directly to the nRF52832 on the nRF52DK. There are no jumpers or solder bridges in between.

    Hello Bjorn,

    I added a breakpoint before nrf_fstorage_erase() in nrf_dfu_flash, using if(page_addr==0x0007F000) to catch the problematic call. The moment nrf_fstorage_erase() returns, rc is set to 0.

    nrf_fstorage_erase() and nrf_fstorage_write() both return 0, the error is printed by dfu_fstorage_evt_handler()

    ret_code_t nrf_dfu_flash_erase(uint32_t                 page_addr,
                               uint32_t                 num_pages,
                               nrf_dfu_flash_callback_t callback)
{
    ret_code_t rc;

    NRF_LOG_DEBUG("nrf_fstorage_erase(addr=0x%p, len=%d pages), queue usage: %d",
                  page_addr, num_pages, m_flash_operations_pending);

    if(page_addr==0x0007F000)
      NRF_LOG_INFO("0x0007F000");

    //lint -save -e611 (Suspicious cast)
    rc = nrf_fstorage_erase(&m_fs, page_addr, num_pages, (void *)callback);
    //lint -restore
    NRF_LOG_INFO("nrf_fstorage_erase() returned %d in nrf_dfu_flash", rc);


    if ((NRF_LOG_ENABLED) && (rc == NRF_SUCCESS))
    {
        m_flash_operations_pending++;
    }
    else
    {
        NRF_LOG_WARNING("nrf_fstorage_erase() failed with error 0x%x.", rc);
    }

    return rc;
}

    Ah, my bad. I now see that the log messages does not fit and it makes sense as nrf_fstorage_write/erase will only queue the flash operations which are asynchronous. So the queuing of the flash operations are ok, but the operation it self( which occurs afterwards) fails with NRF_ERROR_INTERNAL. 

    The question is then why would the erase and write operations fail with NRF_ERROR_INTERNAL.

    Do you see this issue on multiple custom boards or just one?
