orange pi 2w does not boot

What I did

Buildroot commit sha1: 2024.08-rc3 and 2024.02

Distribution of the build machine: Ubuntu 22.04.4 LTS

  • I built sdimage.img and u-boot-.bin successfully.
  • After flashing the image file to the SDcard (using Raspberry Imager and dd command, too), plugged it into my Orange Pi 2W, the board did not boot up, the green LED does not light up as usual, the monitor stays black. Following are the commands used to flash the image files
$ sudo dd if=output/images/sdcard.img of=/dev/sda bs=4M status=progress oflag=direct
$ sudo dd if=output/images/u-boot-sunxi-with-spl.bin of=/dev/sda bs=1024 seek=8
