Function nrfxlib_sys::nrf_modem_full_dfu_bl_write

pub unsafe extern "C" fn nrf_modem_full_dfu_bl_write(
    len: u32, 
    src: *mut c_void
) -> c_int

Write a booloader chunk to the modem.

Call after nrf_modem_full_dfu_init() to upload modem bootloader segments. Bootloader segments are appended together, so the full bootloader may be uploaded with one or many call to this function. Once the full bootloader is uploaded, call nrf_modem_full_dfu_apply().

Firmware segments can be uploaded after successful bootloader upload.

On failure, errno is set to one of following values:

• NRF_EINVAL When src pointer is NULL or user tries to upload too big bootloader.
• NRF_EOPNOTSUPP If the modem is not in a state to receive.
• NRF_EFAULT When modem responded with error codes.
• NRF_EPERM When modem did not accept the flash programming request.
• NRF_ENOEXEC When flash programming failed.
• NRF_ETIMEDOUT When modem did not respond.
• NRF_EIO When incorrect response received from modem.

• len - Length of data to be written.
• src - Pointer to the buffer where chunk data is stored.

Returns 0 if the procedure succeeds, -1 otherwise.
