If you pull the branch v2018.04.0/topic/rpi from git://git.pengutronix.de/rhi/barebox, you should get a barebox-raspberry-pi-3.img. (I think that branch should also be able to be rebased onto the current master, but I have not tested that.) The rest of your steps below look fine to me. - Roland > > 2. export ARCH=arm and export CROSS_COMPILE=/usr/bin/arm-linux-gnueabihf- > > 3. make rpi_defconfig > > 4. make => generates the images barebox-raspberry-pi-1.img and > barebox-raspberry-pi-2.img but no barebox-raspberry-pi-3.img! > > 5. copy barebox-raspberry-pi-2.img to SD card and rename to barebox.img > > 6. create config.txt with kernel=barebox.img enable_uart=1 > dtoverlay=pi3-miniuart-bt > > 7. turn on raspberry pi (connected with HDMI and UART) but it gets stuck at > the rainbowscreen with no UART output. > > => But booting with the default image from NOOBS is working perfectly. > > My PC is set up with gcc version 7.3.0 (Ubuntu/Linaro 7.3.0-27ubuntu1~18.04) > and I tried with Raspberry Pi 2 Model B, Raspberry Pi Zero W and Raspberry Pi > 3 Model B. > > Do you have any idea why it is not working?
