1  Hardware and U-Boot firmware / U-Boot stuff / Re: SheevaPlug-installerv1.0 and kernel 2.6.32 on: July 28, 2010, 10:15:12 AM
Well - I took a risk and did the following which seems to work, but still if anyone would like to chime in and tell me if I am doing things wrong, then I would greatly appreciate it.

I downloaded kernel 2.6.32.2 uImage and modules.tar.gz
I replaced the installer-v1.0 files with the two downloaded files.

I ran the installer-v1.0 runme.php script and it seems to boot without any issues.

2  Hardware and U-Boot firmware / U-Boot stuff / SheevaPlug-installerv1.0 and kernel 2.6.32 on: July 27, 2010, 05:44:41 PM
Hi everyone!
I am in a bit of a mess.  My lack of knowledge is driving me insane.
I have successfully "mastered" installing Kernel 2.6.30.2 using SheevaPlug installer v1.0 and now.  This morning, I tried to program a different plug and found out a problem (explained in this thread http://plugcomputer.org/plugforum/index.php?topic=2008.0
where the solution to it is installing kernel 2.6.32 which has a problem with new hardware on newer plugs that causes a clock drift (found in this thread http://plugcomputer.org/plugforum/index.php?topic=2002)

My question is:
Can I use sheevaplug installer v1.0 to install kernel 2.6.32? If not, what would be the best solution to upgrade my Plug to the newer kernel.

Thanks in advance!

4  Linux Stuff / General Linux questions / enabling/disabling services during startup on: June 28, 2010, 04:15:27 PM
hi all,
I am trying to speedup my startup time on my plug and I've been reading about the /etc/init.d directory, as well as the symblinks rcS.d and rcX.d but it is taking time to sink in.

I was hoping some of you could shed some light on this.

I have kernel 2.6.30.2 with (default installer 1.0).  I am mainly using my plug to run a program that listens on a socket and communicates with a client on that dedicated socket - nothing else.  Probably later, I will install CUPS and try to get a printing mechanism implemented but that's all.

Can anyone suggest some of the services that I can get rid of?
I am also looking for any website that explains these services...

any input will be greatly appreciated.

thanks birdman for your reply.

Indeed - it was the mmcinit missing command that got it fixed.

I appreciate your input!
6  Hardware and U-Boot firmware / U-Boot stuff / Booting from SD Card - weird behavior on: June 26, 2010, 04:21:49 PM
Hi everyone!
I've been reading about booting from SD Card on SheevaPlug, and I am very interested in getting this to be my default boot location.

However, if I boot the plug electrically (meaning, I plug it in) I get the following crash dump:

 VFS: Cannot open root device "b301" or unknown-block(179,1)
 Please append a correct "root=" boot option; here are the available partitions:
 1f00            4096 mtdblock0 (driver?)
 1f01          519168 mtdblock1 (driver?)
 Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(179,1)
 [<c00309c0>] (unwind_backtrace+0x0/0xe0) from [<c003db20>] (panic+0x50/0x120)
 [<c003db20>] (panic+0x50/0x120) from [<c0008ec4>] (mount_block_root+0x1d4/0x214)
 [<c0008ec4>] (mount_block_root+0x1d4/0x214) from [<c000916c>] (prepare_namespace+0x16c/0x1c4)
 [<c000916c>] (prepare_namespace+0x16c/0x1c4) from [<c0008734>] (kernel_init+0xc0/0xec)
 [<c0008734>] (kernel_init+0xc0/0xec) from [<c0040b18>] (do_exit+0x0/0x6ac)

so I follow this by pressing the reset button and it goes through just fine.  Does this have to do with not allowing enough time for the SD card to mount? or is it happening due to something else?

I followed this wonderful guide to get my SD Card setup but I doubt it has anything to do with it since I am able to load from SD card, but not as I described above.

dumb alert dumb alert!!!!!!!

Can anyone point me to a page to show me how to upgrade my plug with this latest release?
8  Linux Stuff / Kernel / problem starting my plug on: June 13, 2010, 04:56:08 PM
Hi everyone,
Can anyone provide me some insight what I can do to fix this.  I was working on my plug and all of a sudden it got stuck.  I rebooted and when it was done rebooting, this is what I see on the screen and I can't do anything after that:

Ubuntu 9.04 debian ttyS0

[ OK ] login:  * Starting kernel log daemon...
[ OK ] * Starting OpenBSD Secure Shell server sshd
[ OK ] * Starting periodic command scheduler crond
      fat: exports duplicate symbol fat_add_entries (owned by kernel)
insmod: error inserting '/boot/fat.ko': -1 Invalid module format


Any suggestions would be great!

Thanks in advance
9  Hardware and U-Boot firmware / Hardware / Re: MAC address - all for one and one for all on: April 12, 2010, 08:04:20 AM
Found the label and the MAC address.  I used birdman's suggestion to get the right MAC address set in the plug I have but this will be a temporary fix.

10  Linux Stuff / General Linux questions / Re: FTP - too slow on: April 12, 2010, 08:03:09 AM
How can I get to the u-boot prompt? 
In the meantime you can fix them by adding the right addresses (i.e. what the sticker on the box says) with:
Quote
hwaddress ether 00:50:43:xx:xx:xx
lines to the iface sections in /etc/network/interfaces                          


thanks birdman
this temporarily fixed my MAC address.  However, FTP is still not working properly...
I guess at this moment, I have two issues:
1. FTP not working
2. U-Boot inaccessible (I am wondering if the comment made by pingtoo about the serial connection is what I need to change.... maybe the u-boot needs different settings??)
11  Linux Stuff / General Linux questions / Re: FTP - too slow on: April 11, 2010, 11:39:16 AM
hi pingtoo,
Thanks for the suggestion.  Although I currently have one connected to the network, but I think getting the MAC addresses straightened out is an important step.

How can I get to the u-boot prompt? 

Is it during bootup where the plug counts 3 second waiting for me to hit any key? I tried that but it doesn't work... not matter what keys I hit, the countdown completes and Linux starts up.

thanks!
12  Linux Stuff / General Linux questions / Running with cygwin on: April 10, 2010, 04:43:29 PM
Hi all,
I have a dumb question!!!!
The plug comes with instructions to get the serial connection (COM4) to work with hyper terminal.  Can anyone tell me what I can do to get it to work with cygwin? I am running on Windows XP.

Much thanks
13  Linux Stuff / General Linux questions / Re: FTP - too slow on: April 10, 2010, 04:20:30 PM
I am using TFTP
TFTP isn't FTP.  Which are you using?

.. but I want to be able to use FTP to transfer files instead of copying them on USB stick to transfer, and to run in command line over ssh instead of serial port with hyper terminal.
If you intend to use slogin (i.e. ssh) then why not use sftp, which uses the same daemons and setup.

I will try to install pure-ftp and see what happens.
So what are you using now for the server?
[/quote]

Thanks for your reply.  At the moment, I am trying to diagnose a problem that I am not sure what it is just yet.  I installed pure-FTP as my server but the original problem is not going away. 

My original problem is that when I used to ftp into the Plug, the connection takes forever to get established, if it doesn't time out.  Also, when I do have a connection, it also takes a long time to transfer files.  I thought maybe the current FTP server (that came with the plug) isn't behaving properly.  But now, that pure-FTP is behaving exactly the same, I am starting the beleive that something else is wrong.  I have 2 plugs that behave the same so I am not ruling that it is a hardware issue.... something else is not right.

Any suggestions how to proceed?

Thanks Abra.
I am using TFTP and I am not going through the USB or SDCARD, I am going through the Ethernet.  I am not looking to achieve high transfer speeds but I want to be able to use FTP to transfer files instead of copying them on USB stick to transfer, and to run in command line over ssh instead of serial port with hyper terminal.

I will try to install pure-ftp and see what happens.

Thanks again for the suggestion. 
15  Linux Stuff / General Linux questions / FTP - too slow on: April 06, 2010, 09:05:16 AM
Hi all,
I've been experiencing this extremely annoying problem and it has to do with FTP.  I try to use the FTP to connect to the SheevaPlug (running  kernel 2.6.30-rc6 and Ubuntu 9.04) but the connection doesn't always happen, and when it does, sometimes it takes over a minute to transfer a 10KByte file.

Is this a known problem?
Can anyone recommend a different FTP server to install on the plug?

Thanks in advance
