Thanks for your reply Amnda,

I'm also using nRF7002 to develop my own projects.

I have implement this function by follow your ways,but it's not ideal,espcially at speed and and reliability.

Is there another way to implement OTA similar SMP DFU by thransmisson over UDP at external norflash that is possible to sovle both problems.

Regards,
Yu Xu.

Hi,

You can refer to my colleague's sample to have CONFIG_BOOTLOADER_MCUBOOT=y in the prj.conf and create a child_image/mcuboot.conf with the following content in the application:

CONFIG_SIZE_OPTIMIZATIONS=y
CONFIG_SINGLE_APPLICATION_SLOT=y

# Enable MCUboot Serial Recovery
CONFIG_MCUBOOT_SERIAL=y
CONFIG_UART_CONSOLE=n

CONFIG_MCUBOOT_INDICATION_LED=y

Here is my test project. devzone.nordicsemi.com/.../wifi_5F00_sta_5F00_306740.7z

Beware that this code/configuration is not fully tested or qualified and should be considered provided “as-is”. Please test it with your application and let me know if you find any issues.
