Package: flash-kernel Version: 3.20 Severity: wishlist Tags: patch The patch below adds support for the BeagleBone Black board.
It will require a patched u-boot, or using a uEnv.txt in order to load the boot
script on the first partition on the eMMC or microSD:
# Adjust values to taste:
device=mmc
mmcdev=0
mmcpart=2
script=/boot/boot.scr
uenvcmd=load ${device} ${mmcdev}:${mmcpart} ${loadaddr} ${script} && source
${loadaddr}
I've tested this with the u-boot shipping on current BeagleBone Black boards,
though it may not work with previous u-boot versions that shipped with the
boards. I'll work on patching the u-boot in Debian to support it without
requiring uEnv.txt.
The Machine field will also likely apply to the BeagleBone White, which uses a
different .dtb and may require other changes for flash-kernel to support it.
Not sure what exactly to do about that.
