RSS Bot Posted December 10, 2023 Share Posted December 10, 2023 Description Recently, I accidentally erased an SPI flash with an bootloader installed and tried to reinstall the latest bootloader. But it did not recognize the attached disks and proceeded to TFTP Boot. Only by stopping autoboot and hot-swapping the disks or reattaching did the bootloader recognize it, and I was then able to boot with the command. I investigated and found that the problem occured after U-Boot was updated to v2023.01. This issue has been resolved by applying a patch that was previously used in v2022.07. How Has This Been Tested? By compiling U-Boot from trunk (linux-u-boot-odroidhc4-current_24.2.0-trunk) for v2023.01, v2023.04, v2023.07, v2023.10 and testing those on ODROID-HC4.
