Hi jernst,
Please do “scsi reset” under u-boot to check if your SATA drive can be detected, then do ext4ls to list the file system of your SATA partition. To setup boot from SATA drive is very similar to boot from SD card, except to use scsi instead of mmc as the parameter to the ext4load. We’ll try to get the instructions on the ESPRESSObin wiki, before it is ready, please check the doc at http://wiki.macchiatobin.net/tiki-index.php?page=Use+SATA+drives+in+U-Boot for reference.
Below are the examples for scsi reset and ext4ls
