How can I use my own PAI and DAC?

[SunHuang]

I'm currently using NCS 2.9.0.

However, the default certificate path is C:\ncs\v2.9.0\modules\lib\matter\credentials\development\attestation.

I used the parameters below, but encountered a compilation error. How should I implement this?

CONFIG_CHIP_FACTORY_DATA_USER_CERTS_DAC_CERT="C:/nordic/Matter-Development-DAC-VID-PID-Cert.der"
CONFIG_CHIP_FACTORY_DATA_USER_CERTS_DAC_KEY="C:/nordic/Matter-Development-DAC-VID-PID-Key.der"
CONFIG_CHIP_FACTORY_DATA_USER_CERTS_PAI_CERT="C:/nordic/Matter-Development-PAI-VID-noPID-Cert.der"

Hi, 

Did you add CONFIG_CHIP_FACTORY_DATA_CERT_SOURCE_USER=y? See the certificates obtained during the certification process. 

I added the following configs to the matter/template/prj.conf and got no build error. 

CONFIG_CHIP_FACTORY_DATA_CERT_SOURCE_USER=y
CONFIG_CHIP_FACTORY_DATA_USER_CERTS_DAC_CERT="C:/nordic/Matter-Development-DAC-VID-PID-Cert.der"
CONFIG_CHIP_FACTORY_DATA_USER_CERTS_DAC_KEY="C:/nordic/Matter-Development-DAC-VID-PID-Key.der"
CONFIG_CHIP_FACTORY_DATA_USER_CERTS_PAI_CERT="C:/nordic/Matter-Development-PAI-VID-noPID-Cert.der"

If the above cannot help, please provide the build log and build/app/zephyr/.config file. 

Regards,
Amanda H.
