VIM1S Android 11 Uboot defconfig path

VIM1S U-Boot
1

Hi Team,

We wanted few customization requirements in uboot for VIM1S android 11 sdk. We have modified using menuconfig under bootloader/uboot path and compiled, but it is getting overwritten after ./mk kvim1s .

  1. Can you show me correct pointer to modify the u-boot configuration like defconfig files ?
  2. we also checked under bootloader/uboot/board/khadas/defconfigs/kvim1s_defconfig
    but could not find the required config details in this file.

Regards

bootloader/uboot/board/khadas/defconfigs/kvim1s_defconfigIt is a configuration file under uboot

You need to make two modifications to take effect, as follows

Hi @xiong.zhang,

Thanks for the confirmation. BTW, if we use make menuconfig in bootloader/uboot folder and make some changes, it is again getting overwritten ? is it correct way of doing ?
For example, i have change DDRFW_TYPE from DDR4 to DDR3 with make menuconfig. but it is always showing DDR4 only after compilation?

Regards,
Vijay

Do you want to ensure that the modifications can be compiled properly or modify the defconfig file

if modification can be compile properly is enough

I want to add a kernel module (pl2303.ko, cdc-acm.ko, btusb.ko), I made changes in the file /common/arch/arm64/configs/defconfig, but when building new modules it does not build
