46  Hardware and U-Boot firmware / Hardware / Re: USB not working??? on: June 20, 2011, 12:57:00 PM
Hi,

 Any advice on this?. Should I try to install a previous kernel or do some check?

47  Hardware and U-Boot firmware / Hardware / USB not working??? on: June 13, 2011, 06:22:24 AM
Hi,

 I just upgraded my GP server + to the newer kernel 2.6.37.8. Now the USB seems to stop working. Running the lsusb command:
Code:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

Instead of the usual output I got:
Code:
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
Bus 001 Device 002: ID 05e3:0608 Genesys Logic, Inc. USB-2.0 4-Port HUB
Bus 001 Device 003: ID 05e3:0726 Genesys Logic, Inc.

Seems that something is wrong, could be the hardware or just something wrong in the new kernel??

Thanks in advance,

PacoLM

This will save some time.... http://plugcomputer.org/plugwiki/index.php/ZoneMinder

Not tested with USB cameras, but fully tested and working with IPCams.

Do you have all your 4 cameras using the same IP address???

 Yes, you are, it's a video server with 4 analog cams... sorry.

Hi,

 Find attached the proof of Guruplug load running two ipcams 320x240:

 ZM is a tricky application, to have it working properly there are a lots of tweaks to do.

 Do you have all your 4 cameras using the same IP address???

Hi,

 I'm using my Guruplug for home surveillance running ZoneMinder. My system has 2 IPCams, although I have tried it with 4 cams and works fine. The load is not that high, so maybe the problem is in your configuration. I had to tweak many settings until I got it working properly. Now the plug is working in modect for both cams, monitoring at 3fps and storing the captures when alarmed at 5fps, sending an email to a gmail account with the pictures and the video. It could work faster, but for me these settings are ok.

 Take a look to the wiki: http://plugcomputer.org/plugwiki/index.php/ZoneMinder, I have worked a lot with this, let me know if you need some help configuring ZM. Drop me a PM if need assistance.

 Also, I would like to know how to capture these nice charts. It will help me monitor my guruplug cpu load, now the average is about 40%.
Regards,

PacoLM

Hi,

 I know that could seems a silly question for some of you guys, but for a newbie is important!. Thanks.

The kernel is being written into it's own partition.  The script does not reformat your root filesystem, but does copy the modules onto the root filesystem.


Code:
flash_eraseall -j /dev/$Mtd
nandwrite -pm /dev/$Mtd sheeva-$KVer-uImage

 Please, be more specific in your answer. If I run the commands above in my plug without changing anything in my system, which will be the result, a bricked plug or an updated kernel plug?

 Thanks for your patience!

Hi again,

 Quick question, as nobody answered the doubts I have in my previous post. In my guruplug the setting of the rootfstype is ubifs

Code:
x_bootargs_root=ubi.mtd=2 root=ubi0:rootfs rootfstype=ubifs


 But in the script to upgrade the kernel there are these lines:
Code:
flash_eraseall -j /dev/$Mtd
nandwrite -pm /dev/$Mtd sheeva-$KVer-uImage
The first one, will do a format to jffs2, as seen here
Code:
guruplug-debian:/mnt# flash_eraseall --help (edited)
  -j, --jffs2       format the device for jffs2

So, do I need to change my bootargs or not previously to upgrade the kernel?. My rootfs is not going to change, it's only a kernel upgrade, isn't it?

Please, help me to disipate my doubts, I'm not an expert, but I would like to keep my guruplug updated.

Thanks in advance,

PacoLM

Hi,

 Here are the actual enviroment variables on my Guruplug server plus:
Code:
bootcmd=${x_bootcmd_usb}; ${x_bootcmd_kernel}; setenv bootargs ${x_bootargs} ${x_bootargs_root}; bootm 0x6400000;
bootdelay=3
baudrate=115200
x_bootcmd_usb=usb start
x_bootcmd_kernel=nand read.e 0x6400000 0x100000 0x400000
x_bootargs=console=ttyS0,115200
x_bootargs_root=ubi.mtd=2 root=ubi0:rootfs rootfstype=ubifs
ethact=egiga0
ethaddr=XX:XX:XX:XX:XX:XX
eth1addr=XX:XX:XX:XX:XX.XX
ipaddr=192.168.1.43
serverip=192.168.1.33
filesize=B940000
fileaddr=6400000
stdin=serial
stdout=serial
stderr=serial
arcNumber=2659
mainlineLinux=yes

 As you could see, there are many differences from the recommended settings of the README-2.6.38 (the latest one):
Code:
####### change bootargs, replace nand_mtd with orion_nand and add rootfstype=jffs2
# setenv bootargs rootfstype=jffs2 console=ttyS0,115200 mtdparts=orion_nand:0x400000@0x100000(uImage),0x1fb00000@0x500000(rootfs) rw root=/dev/mtdblock1 rw ip=192.168.1.9:192.168.1.4:192.168.1.4:255.255.255.0:DB88FXX81:eth0:none

 ...mainly in the bootargs section.
 I would like to upgrade the kernel on my plug, but I bricked it in a previous kernel upgrade trial. I ask for help from some expert in this upgrades. Should I change the bootargs of my plug, or should I apply the changes recommended in the upgrade script?

 My plug is using the internal flash to boot the Debian lenny, I do not have any microSD to boot from, as is working fine, I would like to leave it as it is, but with a new kernel. After bricking the plug, I finally was able to put a new kernel and the performance of the application I use it for improved a lot.

 Another question is regarding the uboot, is this version 'U-Boot 2010.03-01161-gd91b0a9 (Apr 22 2010 - 03:24:41) ' compatible with the new kernel or do I need to upgrade it too?

 More information, these are the partitions created on NAND:
Code:
Creating 3 MTD partitions on "orion_nand":
0x000000000000-0x000000100000 : "u-boot"
0x000000100000-0x000000500000 : "uImage"
0x000000500000-0x000020000000 : "root"

 And the actual kernel version:
Code:
Linux guruplug-debian 2.6.33.7 #3 PREEMPT Thu Dec 9 14:14:08 EST 2010 armv5tel GNU/Linux

 I know that there are a lot of questions, but I'm plenty of doubts before taking the decission!

Thanks in advance,

How could we remove the previous kernel version not used?.

If you're putting your kernel on nand with --nand-write, the only "old" files that you might want to delete would be the /lib/modules/OLD_VERSION.  I leave mine in place until I'm satisfied the new kernel runs well.


 Hi cbxbiker61,

 I have a previous bad experience updating a kernel using a READMEX.X.X file, I had bricked my guruplug. It was my fault, I forgot to set the arcNumber, finally, with the help of many people here, I was able to get it back to life again. I'm pretty worried about upgrading the kernel, so it will be very useful for people like me have a step-by-step guide.
 
 You mentioned the option --nand-write, so know I'm more confused than before... where is this option, in the script to install the new kernel, I only see "--nandkernel" and "--rootkernel". Could you please help me?.

 TIA,

 PacoLM

I was having the same issue; I tried to follow your instructions, to no avail. Finally, after about a week of tinkering (keeping in my that I'm not exactly sure how I did it), I was able to get the sheeva-with-linux kernels working.

I first added the following to my /etc/apt/sources.list :
Code:
deb http://people.debian.org/~tbm/orion lenny main
I then did a:
Code:
sudo apt-get update
followed by:
Code:
sudo apt-get install flash-kernel
Installing flash-kernel and its dependencies creates (I'm not yet sure how) the ability to use the script and install the kernels to NAND. Once the install was complete, I then navigated to where I had stored the README-2.6.32.9 script (which I had already made executable) and ran the following command:
Code:
sudo bash ./README-2.6.32.9 --nandkernel
This wrote the kernel correctly to flash, I rebooted and I was up and running with 2.6.32.9. I hope this helps!

Wow!, that's impressive. So, what are the steps in order to get a guruplug upgraded in this way?. Could you please make a 'guide for dummies'?. Do we need to modify anything in our uboot before run the 'sudo bash ./README-2.6.XX.X --nandkernel' command?. I mean if we need to set the proper arcNumber or whatever. How could we remove the previous kernel version not used?.
 In my case, guruplug server plus running debian in the nand flash, not in a external drive/sd card, so, running the command with the nandkernel option should work, isn't it?

 Thanks in advance,

PacoLM

Hi,

 Newbie question: will the upgrade of kernel need to reinstall all the applications, or are they keep as they are?

Thanks,

Hi,

 Follow the instructions I just updated in the wiki -> http://plugcomputer.org/plugwiki/index.php/ZoneMinder

Hope it helps!
