Despite this being the supported image advertised for the board, it just does not boot on this board, whereas the "current" image does boot (but with limited hardware support). I'm booting with just the serial console connected, to limit interferences On serial console with default config I get: Found U-Boot script /boot/boot.scr 3185 bytes read in 4 ms (777.3 KiB/s) ## Executing script at 00500000 Boot script loaded from mmc 1 117 bytes read in 3 ms (38.1 KiB/s) 7861795 bytes read in 361 ms (20.8 MiB/s) 20770824 bytes read in 941 ms (21.1 MiB/s) 104363 bytes read in 11 ms (9 MiB/s) 2698 bytes read in 7 ms (376 KiB/s) Applying kernel provided DT fixup script (rockchip-fixup.scr) ## Executing script at 09000000 ## Loading init Ramdisk from Legacy Image at 06000000 ...
