1  Hardware and U-Boot firmware / Hardware / Re: Fried Power Supply - Replacement Ideas? on: January 12, 2010, 04:52:02 PM
Hi

Welcome the the Club of Plugs with fried power supply. Roll Eyes

I found USB Hubs to be a cheap source for 5V power supplies. Got a 13Port USB hub with a 4A/5V Power supply (4A is propably overkill, but better save than sorry). It now powers the Plug, the Hub and the devices connected to it (including a 2.5" Hard disk).
Previously i used an 1A power supply for the Plug alone, but it overheated after a day of use and shut itself down together with the plug.
Also tried a power supply from an unused harddisk case, which has a 2A/5V rail, but the plug refused to power up with it. Not sure why this did not work.

Hello

I am slightly puzzled. Do you want to load x86 windows drivers on an ARM Based system or am i missing something? Undecided

Hello

UBoot is the bootloader of the Plug. It can boot from internal flash as well as from the Network. TFTP is used to transfer the Kernel Image from the Remote server to ther plug (similar to PXE). I don't know if UBoot can request the boot info using DHCP like PXE does.

The Wiki has an example with static Network config in the bootloader: http://plugcomputer.org/plugwiki/index.php/Setting_up_TFTP_and_NFS

Okay, figured out what went wrong here:

vol_size in ubi.cfg was set too high (500MB) setting it to 450MB makes it work (didn't try other values).

Now df -h shows 462M rootfs size, which is less than i had with jffs2. Sad
But at least it boots much faster now. Smiley

da1l6,  where is ubi.cfg?  How do I change the value above?

Huh? You manually create the ubi.cfg in the process of bulding the UBI image.

Hello

Assuming that you just copied your root FS to another device you propably forgot to create the basic dev nodes on it. in /dev you need at least these files, to get it booting until udev is loaded
Code:
crw------- 1 root root 5, 1 22. Jul 12:12 /dev/console
crw-rw-rw- 1 root root 1, 3  7. Jun 13:32 /dev/null
crw-rw-rw- 1 root root 1, 5  7. Jun 13:32 /dev/zero

you can create these dev nodes on another linux box with
Code:
mknod /dev/console c 5 1
mknod /dev/null c 1 3
mknod /dev/zero c 1 5

Exactly the same problem here.

Compiled the tools and created the image entirely on the plug.

Kernel 2.6.30.

mkfs.ubifs Version 1.3 (from git head 5cf9d3cf66dd32bd5a348e0e9805c5d7a3c34573)

No solution found so far. Sad

8  Linux Stuff / Kernel / USB not working with kernel 2.6.30-rc5 - "hub has too many ports! (err -19)" on: May 10, 2009, 01:48:10 PM
Hello

When booting the plug with kernel 2.6.30 rc5 (and these patches: http://sheeva.with-linux.com/sheeva/index.php?dir=patches/) USB devices alost never work. dmsg lists this:
Code:
$ dmesg | grep -i hub
usbcore: registered new interface driver hub
hub 1-0:1.0: USB hub found
hub 1-0:1.0: 1 port detected
hub 1-1:1.0: USB hub found
hub 1-1:1.0: config failed, hub has too many ports! (err -19)
There is a single 5 Port USB 2.0 hub connected to the plug.
Repluging the USB hub makes it work again.
With the stock kernel USB works fine.
Any hints on what's going wrong during boot?
