Low cost production programming of the nRF5340 is now available. It can parallel flash multiple boards at once.

It is available at mouser https://www.mouser.com/ProductDetail/I-SYST/CS-BLYST-08?qs=T3oQrply3y%252BhSfpc3hK%2FLg%3D%3D

Parallel flashing software download here https://sourceforge.net/projects/idaplinkfirmware/files/

Hello,

Initial programming of the IC must be done through the debug interface as there is no pre-programmed bootloader on the device. If you want to add UART DFU capabilities, you need to create an application which supports this, and flash that program(.hex) to the nrf5340 with a programmer/debugger, e.g Jlink.

Here is a guide you can look at how to add DFU support to an application: https://devzone.nordicsemi.com/guides/nrf-connect-sdk-guides/b/software/posts/ncs-dfu.

Thanks.

Sorry, I am not able to understand process correctly using the above links: Can you please provide some example or anything which show how to configure the code to flash first firmware image into the production ready nRF5340.
