I think the reason why ... is cause you probally haven't added the blkmem
the right way. Plus you haven't changed the BLKMEM_MAJOR number not the
right way:
Can't allocate major number 31 for Memory Technology Devices.
The blkmem and mtd use the same BLKMEM_MAJOR number so you'll need to change
this. It's best to follow the steps according to this site:

Subject: RES: [uClinux-dev] How to mount a jffs2 in M5208EVB
Date: Fri, 18 May 2007 17:53:27 -0300
I finally got to build the uClinux so I could try to mount the jffs2.
But now I have another problem. I get the following error when I try to
mount JFFS2 (mount -t jffs2 /dev/mtdblock1 /mnt):
arena open of 1 failed!
mount: Mounting /dev/mtdblock1 on /mnt failed: No such device
Any Idea how to fix this?
Bellow I am coping the uClinux initialization from the image Ive built.

Assunto: [uClinux-dev] How to mount a jffs2 in M5208EVB
Hi,
I am using my M5208EVB (Freescale evaluating board ) to make a GPRS
router using uClinux. It was going fine, but now I need a non-volatile
memory to save some files and initialize them when then uclinux starts.
So I am trying to mount jffs2 to create a folder (/mnt/flash) where I
can save my files.
I have built a different uClinux image (using menuconfig toolchain:
m68k-uclinux-tools-20060615.sh) with some programs to make my router
works (for example: pppd, chat, ifconfig
), but I am having problems to
mount my jffs2.
Ive found this site
http://www.enseirb.fr/~kadionik/embedded/uclinux/mtd/howto_mtd.html that
teaches how to mount jffs2 for a M5407C3 Motorola board and FLASH memory
(AMD Am29PL160C). I tried to build 2 different images: one where I
change the uClinux-dist/linux-2.4.x/drivers/mtd/maps/physmap.c to choose
the partitions that I want in my flash memory, and the other way that I
choose in menuconfig to use
uClinux-dist/linux-2.4.x/drivers/mtd/maps/m5208.c (default file for
M5208EVB), but in both cases I get errors during the make process.
Bellow Im coping these errors messages:

In that site it says to build uClinux image using kernel 2.4.x, is there
any problem in using kernel 2.6.x? (ps: I also tried to build an image
using kernel 2.6.x and I also got errors during the compilation)
Does any one have any idea how I can solve my problem? Is there any
documentation that teaches how to do it?
Thanks,
Roger
