Sorry for being late on this. I just rebased my tree on origin/master
and got rid of my preliminary P2371 patches in favour of this only to
notice that it doesn't work the way it used to. For example I used to
use:
# ums 0 mmc 1
to upload kernel, DTB and such to the external SD card. Unfortunately
that no longer works with this version of the patches. I tried to see
what the differences are but couldn't spot anything. I see that dmesg
shows a bunch of USB device reset messages, and failures to read the
superblock on /dev/sdc, which is what the mass storage shows up as. I
also tried porting a couple of changes from my earlier tree over to
master, but to no avail.
Any ideas what could be the reason here? Does the external SD card work
for anybody else?
It certainly did when I tested it. I haven't tested it on this
particular board since the patch was actually applied though.
A few questions:
- Do regular filesystem commands such as part list, ls, load work on the
SD card?
- Does ums work on the eMMC but not SD, or fail on both?
Perhaps related: I have just noticed that one of my SD cards works just
fine in p2371-2180 but the other card doesn't. I swear they both used to
work. Unfortunately I can't test those cards on p2371-0000 since it has
a uSD slot instead of full-size. I've also noticed some stability issues
with "ums" even on the eMMC; basic stuff like the device enumeration and
various sized dd operations work fine, but mounting filesystems doesn't
always work. I'll see if I can work out what's up. I wonder if the
recent T210 clock driver patches had anything to do with this; IIRC they
didn't exist when I first did all these board ports.
Well, I found what was preventing one of my SD cards from working; the
fix is:

[PATCH] ARM: tegra: fix PLLP frequency calc on T210
ums is still solid for me with dd but unreliable with mount. Still
investigating that one.
