ncs2.8.0 Matter Light sample code not working

[H-ogawa]

Hi,

The sample code does not work with ncs2.8.0.
The board I am using is a custom board.
Custom boards do not have an external flash.
I was able to evaluate it with ncs2.6.0 without an external flash, but is it not possible to evaluate it with ncs2.8.0?

Best regards,

Hiroki

Hi, Hiroki.

I also asked the same question.

An external Flash seems to be required.

Best regards.

 Questions: External Flash required for Matter? 

[Marte Myrvold]

Hi,

Correct. External flash is required because the Matter specification requires that all devices support DFU, and the nRF52840 cannot support DFU with only internal flash.

Best regards,
