| 16:52.28 | merlin1991 | pong |
| 16:53.15 | Pali | merlin1991, I have program which write kernel version which is flashed into mtd3 |
| 16:53.28 | Pali | http://atrey.karlin.mff.cuni.cz/~pali/kernel-version.c |
| 16:54.12 | Pali | it will scan for piggy.gz in zImage format, try to unpack piggy.gz and try to find version string |
| 16:54.27 | Pali | working with mtd or block device or with regular file |
| 16:54.52 | Pali | merlin1991, can you test it? |
| 16:55.08 | merlin1991 | sure |
| 16:55.27 | Pali | I think this is way how to determinate if user has flashed U-Boot, nokia stock kernel or kernel power |
| 16:55.28 | merlin1991 | though can you make me an arm build of it? |
| 16:55.36 | Pali | http://atrey.karlin.mff.cuni.cz/~pali/kernel-version.armel |
| 16:56.01 | Pali | run as root: ./kernel-version.armel /dev/mtd3ro |

| 16:57.12 | Pali | can you create dump of your mtd3ro? |

| 16:58.31 | merlin1991 | is it safe to just dd if=/dev/mtd3 of=somefile? |
| 16:58.51 | Pali | yes |
| 16:59.03 | Pali | better mtd3ro |
| 16:59.55 | Pali | merlin1991, which kernel version are you using? |
| 17:00.12 | merlin1991 | power46 from the bleeding edge package |
| 17:00.40 | merlin1991 | btw are you going to include the "new" driver from lpx1 into powerkernel? |
| 17:00.57 | Pali | maybe in future in separate package |
| 17:01.23 | Pali | now problem is that kernel-power v50 is builded but not uploaded from autobuilder to extras-devel :-( |
| 17:01.51 | merlin1991 | hm it fails aswell with the stock pr 1.3 kernel |
| 17:02.09 | merlin1991 | ah wait |
| 17:02.26 | merlin1991 | I don't have the stock kernel here but power46-wl1 again |
| 17:02.40 | merlin1991 | trying on yet another n900 :D |
| 17:02.55 | Pali | can you send me dump? |
| 17:03.10 | merlin1991 | yeah I'm only trying to figure out where I dropped my ssh key :D |
| 17:03.12 | Pali | it should show version of each zImage kernels |
| 17:03.16 | Pali | ok |

| 17:05.34 | Pali | ok |
| 17:05.36 | merlin1991 | I'll try to run it against the dump |
| 17:05.49 | merlin1991 | (on the device again) |
| 17:06.13 | Pali | Version: 2.6.28.10power46-wl1 |
| 17:06.16 | Pali | working too |
| 17:06.34 | Pali | can you try to run: ./kernel-version.armel mtd3dump_power46-wl1.bin |
| 17:06.46 | merlin1991 | that works |
| 17:06.55 | merlin1991 | trying again agains /dev/mtd3ro |
| 17:07.11 | Pali | make sure you are root |

| 17:08.17 | Pali | I updated armel binary on server |
| 17:08.29 | Pali | now it show size of file/mtd device |
| 17:08.52 | Pali | check if size output is same |
| 17:09.41 | merlin1991 | Size: 2097152 |
| 17:09.42 | merlin1991 | but still no version info |
| 17:09.55 | Pali | size is ok |
| 17:10.02 | merlin1991 | dd also reads same size |
| 17:10.05 | merlin1991 | ls |
| 17:10.07 | Pali | I will try to investigate where is problem |
| 17:10.33 | Pali | program mapping file to memory |
| 17:10.48 | Pali | so maybe mmap is not working correctly |
| 17:10.59 | merlin1991 | odd thing is it works against the dd dump |
| 17:11.13 | merlin1991 | maybe you can't mmap the /dev device? |
| 17:16.59 | Pali | I will try to find out some more info |
| 17:17.24 | Pali | at least uncompressing and finding correct version string working |

| 17:28.36 | Pali | merlin1991, I found problem. mmap returning (void *)-1 if failed (not NULL) |
| 17:28.54 | Pali | and it failed with errno ENODEV |
| 17:29.10 | Pali | so maybe really mtd dev does not support mmap |
