RE: boot regression with AHCI on jetson-tk1

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I have a retail rev D jetson-tk1, I'm in the lab with Greg Roth, and I tried my sdcard on his rev C and it boots fine.  I've never used SATA on this board, but the l4t kernel boots ok, which at least probes sata without issue.

I thought of u-boot dependencies as well, but I updated to:

commit 46b7b2e8025770fb29f7810c2d7d15a6650b9643

    Merge branch 'master' of git://git.denx.de/u-boot-mips

and it still fails

I just tried this, and everything works out OK for me with 3.18-rc3 or
next-20141016 which I had lying around.

Which board revision are you using? I'm using rev D.

Which U-Boot revision are you using? Perhaps this is an issue with old
U-Boots that don't initialize the full pinmux, now that the kernel
doesn't and hence relies on U-Boot. I tested there weren't any kernel
regressions when I updated it not to program the static pinmux, but
perhaps SATA wasn't enabled when I did that.
