When I build U-Boot according to http://wiki.macchiatobin.net/tiki-index.php?page=Build+from+source+-+Bootloader and write it to SD and reboot I always only get
BootROM - 2.03
Starting CP-0 IOROM 1.07
Booting from SD 0 (0x29)
Found valid image at boot postion 0x002
lNOTICE: Starting binary extension
NOTICE: Gathering DRAM information
mv_ddr: mv_ddr-armada-17.06.1-g47f4c8b-dirty (Oct 15 2017 - 01:08:50)
mv_ddr: completed successfully
U-Boot never appears.
There are some github repositories that have scripts based on the same directions (e.g. https://github.com/hkominos/ENEA_PicoCluster) but they lead to the same result.
The only working image I found was at https://wiki.solid-run.com/lib/exe/fetch.php?media=products:a8040:software:os:flash-image.bin.gz.
Please, add the missing in information to the build instructions to get a working U-Boot image.
Best regards
