Hi Hieu,

Thank you very much. I'll remove these Kconfig in SDK temporarily.

Best regards,

Jayant

Hi Jayant,

Our Matter team also confirms that the default value set in Kconfig.mcuboot.default is what caused the problem. It is not clear why, but it was proven that removing that line allows you to disable QSPI NOR.

This is the link to their PR to fix the issue. You could patch the SDK with it for now: https://github.com/nrfconnect/sdk-connectedhomeip/pull/432.

Best regards,

Hieu

P.s: It appears to be due to <SDK>\modules\lib\matter\config\nrfconnect\chip-module\Kconfig.mcuboot.root. This file should only impact Matter projects. I am not well versed in Kconfig enough to tell why later Kconfig overlay cannot override the configurations here though. I will investigate further for how to get around this.

Hi Jayant,

I haven't figured out where exactly the problem is yet, however, I know this project can successfully use SPI NOR instead of QSPI NOR.

devzone.nordicsemi.com/.../2451.mcuboot_5F00_smp_5F00_uart_5F00_nrf5340_5F00_spi_5F00_nor.zip

I'm sharing this so you could also check alongside me to see where the issue is. I have looked into a few things but still couldn't figure out what the key difference is,

Best regards,

Hieu

Hello Hieu,

The build log says:

warning: NORDIC_QSPI_NOR (defined at
/home/jayant/project/ncs/v2.6.0/modules/lib/matter/config/nrfconnect/chip-
module/Kconfig.mcuboot.defaults:77, /home/jayant/project/ncs/v2.6.0/nrf/Kconfig.nrf:99,
drivers/flash/Kconfig.nordic_qspi_nor:4) was assigned the value 'n' but got the value 'y'. See
http://docs.zephyrproject.org/latest/kconfig.html#CONFIG_NORDIC_QSPI_NOR and/or look up
NORDIC_QSPI_NOR in the menuconfig/guiconfig interface. The Application Development Primer, Setting
Configuration Values, and Kconfig - Tips and Best Practices sections of the manual might be helpful
too.

It seems that this config is enabled by `modules/lib/matter/config/nrfconnect/chip-module/Kconfig.mcuboot.defaults:77`.

I'm sure it's not enabled by `nrf/Kconfig.nrf:99` because I have deleted the flash device tree node on the QSPI node.

The question is why I can't set the CONFIG_NORDIC_QSPI_NOR to `n` ?

Best regards,

Jayant

Hello Jayant,

Do you see any warning in the build log? Usually there should be a warning if a user configuration cannot be realized.

Another thing to check in the build log is whether the child image overlay has been included correctly. This can also be checked in the nRF Connect Extension for VS Code.

Best regards,

Hieu
