[LS1046A] The added kernel config disappeared

[charleshuang]

Hi NXP Team,

Our platform is LS1046A and use LSDK20.12.

We enable several options in "arch/arm64/config/defconfig" as below :

...

CONFIG_WLAN_VENDOR_REALTEK=y
CONFIG_RTL_CARDS=y
CONFIG_RTW88=y
CONFIG_RTW88_CORE=y
CONFIG_RTW88_PCI=y
CONFIG_RTW88_8822BE=y

...

And then, after execute command "flex-builder -c linux -a arm64", we check the ".config" file in directory "build/linux/linux/arm64/LS/output", but we can't find those options that we set. Those configurations only appear in the ".config.old".

Something wrong with this place?

Thanks~

Please refer to the following to reconfigure Linux Kernel.

1. $ flex-builder -c linux -a arm64

2. Please go to folder flexbuild_lsdk2012/build/linux/linux/arm64/LS/output/LSDK-20.12-V5.4, run the following command to enable your options.

$ make ARCH=arm64 menuconfig

3. Please run the following command to rebuild Linux Kernel.

$ flex-builder -c linux -a arm64

I am trying these instructions to build linux for the LS1088ARDB. I have tried running on two different ubuntu distributions, but got (different) errors both times.
