Hello,
For w few days i try to build Linux image with Buildroot which support CAN0
and CAN1 interface. I successfully use those interfaces with Debian image
provided by BeagleBone.org, but this official image has a lot of stuff
which i don't need and also has a very long booting time.
I build
How to enable power button in Beaglebone Black Rev C?
Here is my device tree from i2c and tps:
i2c0_pins: pinmux_i2c0_pins {
pinctrl-single,pins = <

Hello,
how to flash system image created by buildroot to internal eMMC memory in
BBB?
Here is what I'm doing:
1. Build image with buildroot
2. Write sdcard.img to SD card
3. Boot BBB from SD card
4. Increase root partition on SD card: resize2fs /dev/mmcblk0p2
5. scp sdcard.img from PC to BBB:
It looks like the eMMC is properly recognized by uBoot:
