+ | * On Raspberry Pi, Device Tree usage is controlled from /boot/config.txt. By | ||
+ | default, the Raspberry Pi kernel boots with device tree enabled. You can | ||
+ | completely disable DT usage (for now) by adding: | ||
+ | <code> | ||
+ | XXXXXX---- nefunguje device_tree= | ||
+ | </code> | ||
+ | * mozna chcem novy git clone https://github.com/RPi-Distro/raspi-config | ||
+ | * a tam poresit tree | ||
