31	Linux Stuff / General Linux questions / Re: HOWTO mount JFFS2 image on Linux host without NAND flash	on: April 16, 2009, 07:06:03 AM
Don't know if it helps, but here is what I do to mount a JFFS2-Image on my Debian-Box: Code: linBox:/home/kaibo# modprobe mtdblock linBox:/home/kaibo# modprobe jffs2 linBox:/home/kaibo# modprobe mtdram total_size=200000 linBox:/home/kaibo# cat /proc/mtd dev: size erasesize name mtd0: 0c350000 00020000 "mtdram test device" linBox:/home/kaibo# dd if=/usr/src/sheeva/Image/ubuntu.jffs2 of=/dev/mtdblock0 278272+0 records in 278272+0 records out 142475264 bytes (142 MB) copied, 2.59761 s, 54.8 MB/s linBox:/home/kaibo# mount -t jffs2 /dev/mtdblock0 /mnt linBox:/home/kaibo# ls /mnt bin dev home media opt root selinux sys usr boot etc lib mnt proc sbin srv tmp var And yes, all files are there - not only the directories.

Quote from: tmk on April 15, 2009, 10:10:31 PM It seems to pause on boot, just after initalizing eth0. It seems like it's scanning the flash or something. Is this normal? Code: md: autorun ... md: ... autorun DONE. eth0: link up, full duplex, speed 100 Mbps ..... pause ~ 60 seconds ..... Empty flash at 0x0e2b2080 ends at 0x0e2b2800 VFS: Mounted root (jffs2 filesystem). ... -tmk Mine does that as well. For me it not only does this when booting but when doing other stuff as well - I notice it during heavy io-operations (from/to nand/usb/mmc). Regarding the Bad Blocks: I have 19 of them in total. As long as they have been marked as such it shouldn't be a problem. Bad Blocks on Flash-Devices are, while not convenient, common and hence tolerated and handled accordingly. However, there should not be an increase of Bad Blocks.

Quote from: Phoenix on April 15, 2009, 04:06:05 PM I found that I had to set mainlineLinux to yes, then reset the plug and set arcNumber before that went away. I can confirm that. Having it done that way it works like a charm!

Quote from: Raúl Porcel on April 15, 2009, 10:15:11 AM I've updated the wiki regarding that: http://plugcomputer.org/plugwiki/index.php/Compiling_Linux_Kernel_for_the_Plug_Computer#Troubleshooting Thanks a lot for the fast response on this! However, the error stays the same. Is there an additional chip needed in the kernel-config? On a sidenote (even though it might be obvious): Having the enviroment-variables set as described in the Troubleshooting-Chapter results in the original kernel not booting anymore.

Compiled my Kernel yesterday (almost) without hassles. It took the approximated 45 Minutes on the Plug itself, which is fine for my purposes. But somehow I must have missed something. I set everything up as stated in the Wiki (getting kernel using snapshot) and compiled it using the steps provided by moshiach in this thread (Thanks for that!). However, after flashing the Image and booting it, I get this: Code: Error: unrecognized/unsupported machine ID (r1 = 0x0000020f). Available machine support: ID (hex) NAME 00000690 Marvell DB-88F6281-BP Development Board 00000691 Marvell RD-88F6192-NAS Development Board 00000682 Marvell RD-88F6281 Reference Board 00000831 Marvell SheevaPlug Reference Board 0000085b QNAP TS-119/TS-219 Please check your kernel config and/or bootloader. Did I miss something? Maybe a kernel-option that is not being set by using make defconfig? Even though I find it odd that a SheevaPlug is listed as supported...
