Fwd: Replicating Linaro Images to more memory cards
Ohh that's super. My replicated memory card is working. Thanks Nicolas and
Waddel for quick help.
Can't Linaro image be made generalised so that I can put the image in any
memory card/any hardware.?? So that replication becomes easy.
Little more to go:
Using the replicated memory card, my Wi2Wi WiFi module on another
Overo-Fire is not working. Network manager doesn't detect any WiFi modules.
How can I make this work. I suppose the replicated linaro is looking for
the older WiFi module which was on it's previous Overo-Fire hardware. I
have 4 Overo-Fires with me, all with same make Wi-Fi modules.
-- How can I generalize the Linaro so that replicated Linaro will detect
any other Hardware's WiFi module.
More over at the console messages i get a lot of error messages like::
[6.924926] usbcore: registered new interface driver usbhid
[6.936523] usbhid: USB HID core driver
[8.731719] uncorrectable error :

This repeats for some for 1000 lines with different mtdblock# and different
sectors.
-- I suppose this will eat up CPU time and memory - both are crucial for
my setup.

Yes Nicolas, in the console message during boot i could find the line
root=UUID=xxx like:

I tried giving the whole bootargs command in the boot console after
interrupting the boot, the situation is still the same.

I found the line in boot.txt in the boot partition of the memory card. I
did change that line in boot.txt to root=LABEL=rootfs, nothing changed in
the kernel command line, it was still as shown above.
I want to know where exactly i have to change the boot args from UUID to
LABEL.
Is there a boot.scr file in the same directory as the boot.txt file? If
there is, then the boot.txt file is only showing the text contents of
boot.scr file. To make a change to the boot script you need to; first
make the changes in the boot.txt file, second run this command:
mkimage -A arm -T script -C none -d boot.txt boot.scr
Incidentally, if mkimage isn't installed on your system then
apt-get install u-boot-tools will install it.
Best regards,
Matt

it looks like you are using UUID in the bootargs (root=UUID=xxx) to
indicate where the root FS is. You can use a LABEL instead of UUID,
root=LABEL=foobar, and make sure that on all your cards the root
partition
is labelled 'foobar'

You can change this to something like: linaro-media-create --dev overo --image_file file.img --image_size 3G This will create file.img which you could then dd to your SD cards. ___ linaro-dev mailing list linaro-dev@lists.linaro.org http://lists.linaro.org/mailman/listinfo/linaro-dev
