Hi. Thansk a lot for this guide and topic. I'm really appretiate it. But I need help with "silent" U-boot. Now I'm running Armbian 23.02.2 Jammy on RockPi4A 1.43. System installed on Kingston A2000 512GB and perfectly booting from SPI-flash XT25F32BW soldered on the board by manufacturer. I flashed rkspi_loader-v20.11.2-trunk-v2.img from this topic using dd command. The next step is to make some cosmetic changes. I'm using vertical orientation screen and boot process for me looks no so good (boot_1, boot_2, boot_3). I decided to make u-boot with "remove-boot-messages-from-hdmi" patch from neighbour topic. So, my steps was:
sudo apt install git
git clone --depth=1 --branch=main https://github.com/armbian/build
Then I put files board-rock-pi-4-enable-spi-flash.patch (from "patches" folder) and remove-boot-messages-from-hdmi.patch (from neighboug topic) to "userpatches" folder and run
./compile.sh u-boot BOARD="rockpi-4a" BRANCH="edge"
After executing script i had linux-u-boot-rockpi-4a-edge_23.05.0-trunk--2022.07-Se092-Pbb0c-Bc990_arm64.deb in output. Then I used dpkg -x command to unpack. As a result I have rkspi_loader.img that I flashed to SPI IC using dd command. And finally my system didn't boot. The only way to make it bootable again is to flash rkspi_loader-v20.11.2-trunk-v2.img again. I tried a lot of patches combinations. So, my question is how to compile working SPI image with one of this options:
1. vertical orientaton output
or 2. turned off HDMI output
or 3. boot image during u-boot instead of text output
Any option is ok. Or maybe somebody can compile u-boot for me with any of 3 options above? Thanks
