Hi Simon:
Nice to meet you.
The u-boot I used is based on v2023.04 tagged version.
Layerscape LX2160A RDB board has four SATA controllers.
Based on LX2160A RDB board and two or more SATA disks connected.
I encounter one "scsi scan" problem.
After the first SATA disk is detected and probed properly in the first "scsi
scan".
The other disks would complain that "EFI_NOT_FOUND" error listed below,
when run the first "scsi scan" command in uboot environment.
Does this error matter?
BTW, "scsi info" says that all disk info can be dumped, and all disks are works
well,
after the first "scsi scan"
In the consecutive rescan operations issued by "scsi reset" or "scsi scan"
commends,
the disks would report "unable to unbind devices (-1E)" error.
The first disk is disappeared at all after the next "scsi scan" operations is
finished.
Did you used to encounter such kind of issue?
Any suggestions and guidance are very appreciated.
