ble_dfu_buttonless_async_svci_init return error 0x04 (no memory)

[lyrics]

Hello, I'm using nrf52833, pca10100.

My project is based on 'ble_app_uart', and I added buttonless DFU project.

this is ble_dfu_buttonless_async_svci_init() function, and error return nrf_dfu_svci_vector_table_set() function.

uint32_t ble_dfu_buttonless_async_svci_init(void)
{
    uint32_t ret_val;

    ret_val = nrf_dfu_svci_vector_table_set();
    VERIFY_SUCCESS(ret_val);

    ret_val = nrf_dfu_set_adv_name_init();
    VERIFY_SUCCESS(ret_val);

    ret_val = nrf_dfu_svci_vector_table_unset();

    return ret_val;
}

nrf_dfu_svci_vector_table_set() fucntion is this.

uint32_t nrf_dfu_svci_vector_table_set(void)
{
    uint32_t err_code;
    uint32_t bootloader_addr = BOOTLOADER_ADDRESS;

    NRF_LOG_INFO("%x", bootloader_addr);

    if (bootloader_addr != 0xFFFFFFFF)
    {
        NRF_LOG_INFO("Setting vector table to bootloader: 0x%08x", bootloader_addr);
        err_code = sd_softdevice_vector_table_base_set(bootloader_addr);
        if (err_code != NRF_SUCCESS)
        {
            NRF_LOG_ERROR("Failed running sd_softdevice_vector_table_base_set");
            return err_code;
        }

        return NRF_SUCCESS;
    }

    NRF_LOG_ERROR("No bootloader was found");
    return NRF_ERROR_NO_MEM;
}

#define BOOTLOADER_ADDRESS      ((*(uint32_t *)MBR_BOOTLOADER_ADDR) == 0xFFFFFFFF ? *MBR_UICR_BOOTLOADER_ADDR : *(uint32_t *)MBR_BOOTLOADER_ADDR) /**< The currently configured start address of the bootloader. If 0xFFFFFFFF, no bootloader start address is configured. */

Why my BOOTLOADER_ADDRESS defined 0xFFFFFFFF?

What is this mean? and how can I fix this issue?

This is define value

Hi

If you see the comment on the #define BOOTLOADER_ADDRESS it says "The currently configured start address of the bootloader. If 0xFFFFFFFF, no bootloader start address is configured." So that means you have not defined your bootloader address at all which you need to do.

Best regards,

How can I define bootloader address? Which example should I refer to?

(Is this post a reference book for my work ahead?)

I searched about dfu through googling, but I still don't understand it well.

yes, the "Programming the bootloader" section tells you how to set the Bootloader address. This should also be done in any of the DFU bootloader examples available in the nRF5 SDK. I would recommend choosing the one closest to what use case you are planning on for your project.

Best regards,

Simon
