32  Hardware and U-Boot firmware / U-Boot stuff / Losing USB-HDD / Not found during reboot on: May 10, 2012, 03:30:23 AM
SheevaPlug with DNEX u-boot 2011.12-3 running Debian Squeeze from SD, Hitachi SimpleDrive 3 http://www.hitachigst.com/support/index-files/sd3-technical-support connected to USB

I have the odd problem that the plug sometimes loses the attached USB-HDD. A simple reboot is not good enough to mitigate the situation

Though an

Bus 001 Device 002: ID 4971:ce23 SimpleTech
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

shows it, it can't be mounted (no device /dev/sXY)

Only solution is to power cycle both the plug and the USB-HDD (which is hard to be done from remote Wink)

Can I rescan / reinitiate the Plugs' USB-Port for new devices from Squeeze?

No direct contribution, but which Plug are you using and which uboot is an that device? (Not saying that updating uboot will fix this!?)

I think the Wiki@http://plugcomputer.org/plugwiki/index.php/Factory_Default_u-Boot_Environment has a copy of a "default" config

OK, thx. jFYI As I updated the DNEX version on my spare SheevaPlug yesterday evening from 2011.03 to 2011.12 without any issues (u-boot settings survived the update), I repeated the update this morning on my "production" system, again without any issues.

Re another post I came across that Martin Michlmayr is pointing to an updated and more recent DENX u-boot version in his guide on http://www.cyrius.com/debian/kirkwood/sheevaplug/uboot-upgrade.html

Before digging into any DENX change logs and before giving it a try on my SheevaPlugs:

Would be someone able and willing to tell us kindly, what we could expect as fixes and/or enhancements on the Marvell side of the house? (Or if it's just mentioned by Martin, because it's the latest version available for the Plugs and want to kept his site up to date?)

Though the SheevaPlugs is a ARMv5TE-compliant version only!? ;-)

I saw an expression earlier about 'giving the ghost' and became curious if it was also in other languages or if this gave your nationality away  Tongue

LOL "Great minds think alike, fools seldom differ" (me [giving away my nationality: a little more south and east than you Wink] stumbled over the same phrase a few days, ago.

However: while looking it up I came to the surprising finding - yes it's really used that way.

I had one occurence of the USB key un-mounting itself for no reason

yes and no: I wanted to replace a USB2.0 Hitachi Drive by an USB3.0 HDD. But

i) I could get the latter only to be recognised by the SheevaPlug by connecting it via an USB-Hub
ii) the USB3.0 tended to disconnect itself from time to time

==> I sticked with the USB2.0 drive

@ll,

just updated my SheevaPlugs from Pingtoo's Marvell based U-Boot version to the DENX 2011.03 one as suggested by Martin Michelmayr (http://www.cyrius.com/debian/kirkwood/sheevaplug/uboot-upgrade.html).

However while using the previous installed sheeva-ubootenv-print command I find it still showing my "old" U-Boot's environment variables?!

So the DENX U-Boot is saving it's config at a different place in NAND!?

Also just updated the uboot on my test SheevaPlug from Pingtoo's version to the latest DNEX:

Here's my quick and dirty way how I modified Martin's boot commands to be able to boot into the Ubuntu in NAND, if no SD is attached to the device:

Code:
setenv bootargs_nand 'rootfstype=jffs2 console=ttyS0,115200 mtdparts=orion_nand:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs) rw root=/dev/mtdblock1 rw ip=10.4.50.4:10.4.50.5:10.4.50.5:255.255.255.0:DB88FXX81:eth0:none'
setenv bootcmd_nand 'setenv bootargs $(bootargs_nand); nand read.e 0x800000 0x100000 0x400000; bootm 0x800000'
setenv bootcmd 'setenv bootargs $(bootargs_console); run bootcmd_mmc; bootm 0x00800000 0x01100000; run bootcmd_nand'
saveenv

Slightly OT here:

"thinking ahead" lately, I was curious how I might bring my Squeeze based SheevaPlug to Wheezy when the time will come.

As I'm a U*X n00b andf as I didn't find any upgrade guidelines for squeeze -> wheezy, yet, I think I adopted this one http://www.go2linux.org/how-to-upgrade-from-debian-lenny-to-squeeze, which explains the steps for Lenny to Squeeze. IMO the upgrade worked, though I did it on a spare plug with a fresh squeeze install only at that point in time.

When I have some spare time maybe I'll be "brave enough" to try it on my production device (after cloning the SDHC card, though  Wink). Or is there anything else I should consider, first?

Ups, sorry - yes, you're on a DreamPlug. If I recall correctly there have been discussion here about the usage of such tools on other variants than the SheevaPlug. But as I just use the latter I haven't followed them closely enough to make any suggestion ...

So any ideas what to do?

maybe suffering from a faulty power supply?
