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 : [ 8.735687] uncorrectable error : [ 8.745086] end_request: I/O error, dev mtdblock0, sector 0 [ 8.761077] Buffer I/O error on device mtdblock0, logical block 0 [ 8.794738] uncorrectable error : [ 8.798309] uncorrectable error : [ 8.807281] end_request: I/O error, dev mtdblock0, sector 0 [ 8.822998] Buffer I/O error on device mtdblock0, logical block 0 [ 8.889343] uncorrectable error : [ 8.893005] uncorrectable error : [ 8.901794] end_request: I/O error, dev mtdblock0, sector 0 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. --------------------------------- Sudhangathan BS Ph:(+91) 9731-905-205 --------------------------------- On Sat, Feb 18, 2012 at 11:59 AM, Matt Waddel <matt.wad...@linaro.org>wrote: > On 02/17/2012 08:42 PM, Sudhangathan B S wrote: > > Thanks Nicolas, that sounds very promising, probably something silly is > > missing, for it is not working, > > > > Yes Nicolas, in the console message during boot i could find the line > > root=UUID=xxx like: > > [ 0.000000] Built 1 zonelists in Zone order, mobility grouping on. > > Total pages: 61952 > > --> [ 0.000000] Kernel command line: console=tty0 > console=ttyO2,115200n8 > > root=UUID=17fb7403-3757-4533-b783-7be5436d9882 rootwait ro earlyprintk > > mpuratM > > [ 0.000000] PID hash table entries: 1024 (order: 0, 4096 bytes) > > > > I tried giving the whole bootargs command in the boot console after > > interrupting the boot, the situation is still the same. > > Result:: > > Environment size: 1276/131068 bytes > > --> Overo # setenv bootargs "console=tty0 console=ttyO2,115200n8 > > root=LABEL=rootfs rootwait ro earlyprintk mpurate=${mpurate} vram=12M" > > --> Overo # saveenv > > Saving Environment to NAND... > > Erasing Nand... > > Erasing at 0x240000 -- 100% complete. > > Writing to Nand... done > > Overo # boot > > reading boot.scr > > > > I found the line in boot.txt in the boot partition of the memory card.
