Buildroot BR2_ROOTFS_DEVICE_TABLE Problem

[uruzFR]

Hello,

After few ajustement for my Buildroot OS il found an error.

I needed to have specific pemission on a folder for a single user. So I activated "BR2_ROOTFS_DEVICE_TABLE="system/device_table.txt" in the file . config . But I don’t see any change in the permits, I have breathed the syntax of the official cosumenation but nothing. (User and group are created & detected)

If you have already encountered this problem or you have an idea I am taking.

Thank you !

Hello,

Recently, I had to reuse the device table file to modify the permissions of "/sys/devices/platform/gpio-leds/leds/wan_led/trigger" but during the Buildroot compilation, I received this error message: "table='/home/build/buildroot-rk3328/buildroot/output/build/buildroot-fs/device_table.txt' makedevs: line 21: regular file '/home/build/buildroot-rk3328/buildroot/output/target/sys/devices/platform/gpio-leds/leds/wan_led/trigger' does not exist: No such file or directory"

Subsequently, I tried to modify it manually and it works.

Can you help me ?

Thank you !
