Mine's one of the older models. Certainly > 1 year old. I hope they've improved, as I've recommended the 'plug to a friend as the platform for a product... Rony

Thanks hanker, that's exactly what I needed! My sheeva plug is back from the dead, and my junk box now has some free space, previously taken up by an unused 5V power supply. Cheers, Rony

That's what I was afraid of Thanks for the quick reply. Guess it's time to crack my sheeva open and connect a spare 5V power supply to it directly. Anyone done this before? Rony

4	Hardware and U-Boot firmware / Hardware / Flashing LEDs meaning?	on: April 05, 2011, 11:28:48 PM
Greetings, After disconnecting and reconnecting my SheevaPlug from the mains, I see both the NIC's LEDs and the green LDE (but not the adjacent bue one) flashing at about 2 Hz. Other than that, the device shows no sign of life via USB/console or NIC. Recycling power and the reset button have no effect. Is this what a dying power supply looks like, or is this something else? Thanks, Rony

5	Hardware and U-Boot firmware / Hardware / Re: Suspect bad RAM - how to test?	on: March 03, 2010, 10:02:46 PM
Hi, I think you're seeing an issue with the NAND, which is the built-in flash memory. I'm having problems with the RAM, which is separate. In any case, I've just received an RMA for the device, and am shipping it back to Globalscale Technologies for repair. Rony

6	Hardware and U-Boot firmware / Hardware / Suspect bad RAM - how to test?	on: February 18, 2010, 05:39:38 AM
Hi, I'm getting crashes whenever I do some non-trivial i/o (apt-get safe-upgrade, for example, or just copying files from one FS to another. This happens when booting of a USB drive, NFS or SD card. (I can't manage to boot of nand, which may or may not be related). Finally, the U-Boot 'mtest function freezes as follows: Quote U-Boot 1.1.4 (Dec 23 2009 - 13:32:43) Marvell version: 3.4.27 Marvell>> mtest Pattern 00000000 Writing... Any idea how I can run more diagnostics? I'm attaching the output of the serial port illustrating such a crash.

7	Hardware and U-Boot firmware / U-Boot stuff / Re: nandwrite to /dev/mtd2 crashes kernel	on: February 15, 2010, 10:08:32 PM
Yeah, I thought so too, at first, so I added some swap: Quote # free total used free shared buffers Mem: 515728 9764 505964 0 552 Swap: 80316 0 80316 Total: 596044 9764 586280 This is a recovery process - I'm trying to rewrite the fs that came on the device with that supplied on the cdrom, no reason why this should run out of memory.

Hi, Trying to recover from a munged filesystem, I keep crashing on nandwrite –p /dev/mtd2 ubuntu-9.0.5.Release.jffs2 I suspect it may be related to three bad blocks that are skipped: Quote Code:

10	Hardware and U-Boot firmware / U-Boot stuff / Boot from NFS fails: no init found	on: February 12, 2010, 11:56:08 PM
Hi, Trying to recover from a bad update (which is the topic of another post), I'm booting from tftp/NFS as described in the note from Marvell (Writing Jaunty Filesystem an the NAND flash rev 1.2). All goes well (tftp download, boot, nfs mount) until the kernel starts running. Here are the last few lines on the console: Code: VFS: mounted root (nfs filesystem). Freeing init memory: 124k Warning: unable to open an initial console. Kernel panic - not syncing: No init found. Try passing init= option to kernel. Any solutions/ideas/suggestions welcome! Thanks, Rony
