概要

デフォルト

動作

  • This is read by the GPU before the ARM CPU and Linux are initialised.
  • It must therefore be located on the first (boot) partition of your SD card, alongside bootcode.bin? and start.elf?.

アクセス方法

  • This file is normally accessible as Linux/boot/config.txt from Linux, and must be edited as root.
  • Windows or OS X it is visible as a file in the only accessible part of the card.
