2011-07-17 02:44 <kristianpaul> hahah, finally i'm ready something knwow :)
2011-07-17 02:44 <kristianpaul> damn ack flag signal..
2011-07-17 02:44 <kristianpaul> lets see what happen when writing :)
2011-07-17 02:44 <kristianpaul> hello aw !!
2011-07-17 02:45 <kristianpaul> yeah, i can write as well
2011-07-17 02:45 <aw> kristianpaul, hi hi u got somethings new? hehe ;-)
2011-07-17 02:46 <kristianpaul> soon,i hope
2011-07-17 02:46 <kristianpaul> just dealing with two clocks domains in the milkymsit soc 
2011-07-17 02:46 <kristianpaul> and seems i calm down the beast ;)
2011-07-17 02:47 <aw> good though although i don'et know what story you are building now. ;-)  in the other irc, i need to see backlog, u know. ;-)
2011-07-17 02:48 <kristianpaul> sure, go ahead, just saying hi :)
2011-07-17 02:48 <qi-bot> The build has FAILED, see log here: http://fidelio.qi-hardware.com/~xiangfu/compile-log/openwrt-xburst.full_system-07162011-1957/
2011-07-17 02:48 <aw> yes, calm down..me need to be. :-)
2011-07-17 03:01 <kristianpaul> damn, speak too fast, writing is not working at all
2011-07-17 03:02 <kristianpaul> he, no i'm right, just inverted some parameters..
2011-07-17 03:02 <kristianpaul> oh well, lets implement that channel then
2011-07-17 11:40 <qi-bot> The build has FAILED, see log here: http://fidelio.qi-hardware.com/~xiangfu/compile-log/openwrt-xburst.full_system-07172011-0449/

2011-07-17 20:08 <ignatius_> Hi... after compiling the kernel.. I get this message: "Kernel panic - not syncing VFS: Unable to mount root fs on unknown-block (0,0"  Here is my kernel .config: http://www.armory.com/~ignatius/config.htm -- if anyone could help me out, i'd really appreciate it. Thanks..
2011-07-17 20:11 <mth> how does the kernel get the device to be used for the rootfs?
2011-07-17 20:12 <mth> there is no kernel command line defined there
2011-07-17 20:12 <mth> is it passed via u-boot?
2011-07-17 20:12 <mth> how are you booting your kernel?
2011-07-17 20:13 <ignatius_> Hmm. Good point... although, in the past it (the kernel cmdline) didn't really matter. I got the same error message.
2011-07-17 20:13 <ignatius_> In the mean time, I guess i'll try it again. Thanks.
2011-07-17 20:15 <mth> maybe you don't need it, but then the rootfs device must come from somewhere else, for example u-boot
2011-07-17 20:15 <ignatius_> I'm using the OpenWRT u-boot binary.
2011-07-17 20:16 <ignatius_> It (a previous kernel) worked fine, with what seemed to be that same basic .config
2011-07-17 20:16 <mth> the "unknown-block" suggests that something is wrong there, either there is no device defined or a device of an unsupported type
2011-07-17 20:16 <ignatius_> I don't understand what i'm doing wrong.
2011-07-17 20:16 <mth> and you're building the same type of image?
2011-07-17 20:16 <ignatius_> Yeah. Same kernel. Same everything.
2011-07-17 20:16 <mth> u-boot kernel arguments only work with "uImage", not "zImage", iirc
2011-07-17 20:16 <ignatius_> Same tool chain.
2011-07-17 20:17 <ignatius_> Yes. I'm using the "linux/arch/mips/boot/uImage" file.
2011-07-17 20:18 <ignatius_> In the process of getting the cmdline from the working kernel.
2011-07-17 20:18 <mth> do you still have to old config? if so, it might be useful to run a diff
2011-07-17 20:18 <ignatius_> Yeah. I tried "make oldconfig" but the tool chain didn't like that.
2011-07-17 20:18 <ignatius_> Unless it's "make target/linux/oldconfig" ??
2011-07-17 20:19 <mth> "make oldconfig" doesn't build with the old config, it upgrades a config from an older kernel version to the current version
2011-07-17 20:20 <mth> you have "ARCH=mips" defined?
2011-07-17 20:20 <mth> forgetting that even once can really mess up your kernel config
2011-07-17 20:21 <ignatius_> Ah. I see.
2011-07-17 20:21 <ignatius_> Nah. Since i've been using the same kernel version, there is no previous .config file that I could use.
2011-07-17 20:22 <ignatius_> Well, since i'm able to select the Nanonote in "make kernel_menuconfig" I assume that it is using the ARCH=mips statement.
2011-07-17 20:22 <ignatius_> Here is the kernel cmdline: "mem=32M console=tty0 console=ttyS0,57600n8 ubi.mtd=2 rootfstype=ubifs root=ubi0:rootfs rw rootwait"
2011-07-17 20:24 <mth> ah, OpenWRT might set ARCH for you
2011-07-17 20:24 <mth> I usually build kernels in isolation (for the Dingoo, not the NanoNote, but the hardware is similar)
2011-07-17 20:25 <ignatius_> Ah. Nod.
2011-07-17 20:25 <ignatius_> I just recently got a Dingoo. It's really cool.
2011-07-17 20:26 <mth> if you like to mess with kernels, have a look at OpenDingux, it's basically the NanoNote kernel ported to the Dingoo
2011-07-17 20:26 <mth> with a few extras that are not fully mature yet (cpufreq, double buffering)
2011-07-17 20:26 <ignatius_> Cool.
2011-07-17 20:26 <ignatius_> Compiling the kernel..
2011-07-17 20:26 <ignatius_> (For the NanoNote)
2011-07-17 20:29 <ignatius_> Just like I thought. I got the same error message ("Kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)"
2011-07-17 20:29 <mth> is (0,0) the major/minor number?
2011-07-17 20:30 <mth> in that case it does look like the rootfs device is undefined
2011-07-17 20:30 <ignatius_> I'm not sure, actually.
2011-07-17 20:30 <ignatius_> Ah. Hmm.

2011-07-17 20:31 <ignatius_> How would I define it?
2011-07-17 20:31 <mth> I guess the "root=ubi0:rootfs" part of the command line should take care of that
2011-07-17 20:32 <qi-bot> The build has FAILED, see log here: http://fidelio.qi-hardware.com/~xiangfu/compile-log/openwrt-xburst.full_system-07172011-1341/
2011-07-17 20:32 <ignatius_> Hmm. I wonder why it isn't registering.
2011-07-17 20:33 <ignatius_> JFFS is defined.. ReiserFS is.. Ext2/3/4 is..
2011-07-17 20:34 <mth> JFFS? is it possible that will claim the NAND making it unavailable for UBI?
2011-07-17 20:34 <ignatius_> Hmm. Maybe.
2011-07-17 20:34 <ignatius_> I'll give it a try.
2011-07-17 20:35 <mth> is there anything printed before the fatal message?
2011-07-17 20:35 <mth> for example whether any NAND partitions are found
2011-07-17 20:36 <ignatius_> "UBIFS error (pid 1): ubifs_get_sb: cannot open "ubi0:rootfs", error -19"
2011-07-17 20:36 <ignatius_> "VFS: Cannot open root device "ubi0:rootfs" or unknown-block(0,0)"
2011-07-17 20:36 <ignatius_> Please append a currect "root=" boot option; here are the available partitions:"
2011-07-17 20:37 <ignatius_> Then it lists mtdblock0 thorugh mtdblock3
2011-07-17 20:39 <mth> what is error 19?
2011-07-17 20:40 <ignatius_> I have no idea.
2011-07-17 20:40 <mth> you can check in errno.h or one of its includes (errno-base.h, probably)
2011-07-17 20:41 <mth> in the include/ dir in the kernel source
2011-07-17 20:48 <ignatius_> #define ENODEV          19      /* No such device */
2011-07-17 20:49 <ignatius_> Well, undefined JFFS support.. still won't boot.
2011-07-17 20:49 <mth> ok, so "ubi0" does not exists
2011-07-17 20:49 <ignatius_> Nod.
2011-07-17 20:49 <mth> does it say anything about UBI or NAND earlier in the log?
2011-07-17 20:51 <ignatius_> I'm not sure. I can't scroll back in the buffer.
2011-07-17 20:51 <ignatius_> But, I checked the .config file.. the only "UBI" (besides basic debugging) item that isn't defined is the "XATTR" one.
2011-07-17 20:56 <mth> could you run a diff between this config and a known working one?
2011-07-17 20:56 <mth> anyway, I'm going afk, I'll check back here later
