nrf5340 dk in Matter How to turn off OTA and burn the program into the internal flash without relying on external flash How should I configure it?

[cweib]

I tried adding the following settings to prj.config

CONFIG_CHIP_OTA_REQUESTOR=n

CONFIG_CHIP_QSPI_NOR=n

I've also tried to modify the Devicetree to be the qspi part in any of the routines in nrf's matter, no matter how I modify it, it compiles fine but it doesn't respond to burning the firmware to the development board.

How do I set it up to run the 5340dk without using external flash, or are there any relevant routines I can learn from?

Hi,Charlie

Thanks for the reply, I did a test on the link you gave and unfortunately it still doesn't work, the description in the link is for a CCK development board, I have the same board and it works fine however it comes with external flash on it and mine doesn't have any, but so far in blinky these kind of routines are working fine, but with the matter But all the routines related to matter don't seem to work without an external flash!

Hi Cweib,

Are you sure you are going to turn off OTA and disable external flash on nRF5340 based Matter device?

According to Matter Core Specification, each matter device should implement a method for firmware update for security reasons. 

Matter OTA  provides a convenient way to fulfill this requirement.1.5MB external flash is a minimal request for nRF5340 looking at Matter hardware and memory requirements (nordicsemi.com).
