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: a8b972b 265072b Author: Tom Rini <trini@xxxxxx> Date: Mon Nov 3 12:46:12 2014 -0500 Merge branch 'master' of git://git.denx.de/u-boot-mips and it still fails ________________________________________ From: Stephen Warren <swarren@xxxxxxxxxxxxx> Sent: Wednesday, November 5, 2014 12:10 PM To: Allen Martin; Mikko Perttunen Cc: Mikko Perttunen; linux-tegra@xxxxxxxxxxxxxxx Subject: Re: boot regression with AHCI on jetson-tk1 On 11/04/2014 10:34 PM, Allen Martin wrote: > I tried booting 3.18-rc3 on jetson-tk1 and I'm seeing a hang during > boot right before user space normally comes up.

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. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
