Hello,
We have some issue for a long time now with sata detection in kernel boot.
We observed the following:
1. We used PG 2.1 DM8148, with sata and we see that when the board is still cold the sata is not detected:
" PHY: 0:01 - Link is Up - 100/Full
Link not established, limiting speed
ata1: limiting SATA link speed to 1.5 Gbps
ata1: SATA link down (SStatus 1 SControl 310)
EXT3-fs: barriers not enabled
kjournald starting. Commit interval 5 seconds"
After the board is operated for some time, then tyhe boot is successful in detection of sata:
mmcblk0: p1 p2
ata1: SATA link up 3.0 Gbps (SStatus 123 SControl 300)
ata1.00: ATA-8: SQF-SMSM4-128G-S8E, S8FM06A7, max UDMA/133

2. According to errata on this issue and guidance from e2e, we changed from PG2.1 to PG3.0
But now on trying the same testsm, we get exactly the same behaviour !
Is there any thing that we can do, or bypass this issue ?
Thank you,
Ran
