Changing root password on pico pro max

I would like to change the password of my Luckfox Pico Pro Max. I want to set it directly in my build so that it is preserved.

I found a post from another user stating that this process could be accomplished by replacing the password in <Luckfox-Pico SDK>/sysdrv/tools/board/buildroot/shadow_defconfig, but when I access the buildroot directory, the shadow_defconfig file does not appear.

I would like to know if the password is now configured in a different location, and if so, where I can find it.

Hello, for the method of changing the password, please refer to viewtopic.php?p=1742&hilit=passwd#p1742. I believe you have referred to this post. However, in the latest SDK, all the files that need to be added before packaging have been moved to <Luckfox-Pico SDK>/project/cfg/BoardConfig_IPC/overlay.
