U-boot for BPI-R2/R64/R2Pro

Requirements

On x86/x64-host you need cross compile tools for the armhf architecture:

sudo apt-get install gcc-arm-linux-gnueabihf libc6-armhf-cross u-boot-tools make gcc swig python-dev

Issues

• loadenv failes because of resized environment (4096 => 8188)
  • backup your saved environment before update uboot or change back CONFIG_ENV_SIZE to SZ_4K (./build.sh soc)
  • erase your saved environment

env erase

• no emmc-command (not needed "emmc pconf 0x48" = "mmc partconf 0 1 1 0")

Usage

  #edit build.conf to select bpi-r64 if needed
  ./build.sh importconfig
  ./build.sh config #optional (menuconfig)
  ./build.sh
  ./build.sh install #write to sd-card
  ./build.sh umount #umount automatic mounted partitions
