Intro ===== This default configuration will allow you to start experimenting with the buildroot environment for the Radxa ROCK 4SE. With the current configuration it will bring-up the board, and allow access through the serial console. Radxa ROCK 4SE link: https://radxa.com/products/rock4/4se/ Wiki link: https://forum.radxa.com/c/rockpi4 GPIO connector pinout link: https://wiki.radxa.com/Rockpi4/hardware/gpio This configuration uses mainline ATF, U-Boot and kernel. How to build ============ $ make rock4se_defconfig $ make How to write the SD card ======================== Once the build process is finished you will have an image called "sdcard.img" in the output/images/ directory. Copy the bootable "sdcard.img" onto an SD card with "dd": $ sudo dd if=output/images/sdcard.img of=/dev/sdX $ sudo sync Insert the micro SDcard in your Radxa ROCK 4SE and power it up. The console is available on UART2 on the GPIO connector, 1500000bps 8N1.
