I'm trying to get u-boot working on Raspberry Pi 3 but so far no success. Every time I plug in my SD card to the Pi there isn't any output to the console, only the green LED blinks several times. Currently I'm trying to build u-boot this way:
git clone git://git.denx.de/u-boot.git sudo apt-get install gcc-aarch64-linux-gnu export CROSS_COMPILE=aarch64-linux-gnu- make rpi_3_defconfig make -j8 -s
No errors during building, and here is what I have on my SD card:
bcm2709-rpi-2-b.dtb bcm2710-rpi-3-b.dtb bcm2710-rpi-cm3.dtb bootcode.bin cmdline.txt config.txt fixup.dat kernel7.img overlays start.elf u-boot.bin
In the config.txt I wrote
I built the kernel itself with buidroot but I think the buildroot settings don't matter since I didn't even get output from u-boot.
The kernel7.img loads just fine.
I've already tried several ways to build u-boot (using different compilers like arm-bcm2708-linux-gnueabi- etc., I tried to build u-boot with help of buildroot) but no luck. Every time I turn on my RPi3 the green led blinks several times and nothing shows up in the console. Please, help me with some solid way to build u-boot and make it work on RPi3.
