Problem with build jfss2 filesystem

Altera_Forum · ‎02-02-2007

I do uclinux porting on my own board, use the "uClinux-dist-20060803" released kernel, custom the kernel as follow:

----------------------------------------------------------

Memory Technology Devices (MTD) -->

<*> Memory Technology Device (MTD) support

[*] MTD partitioning support

<*> Direct char device access to MTD devices

<*> Caching block device access to MTD devices

RAM/ROM/Flash chip drivers -->

<*> Support for Altera EPCS Device

Mapping drivers for chip access -->

<*> Maps for Altera EPCS Configuration Device

File systems -->

Miscellaneous filesystems -->

<*> Journalling Flash File System v2 (JFFS2) support

------------------------------------------------------------------

then try "make", but there are some errors:

--------------------------------------------------------------------

--------------------------------------------------------------------

It seems the library-include problem, in "make menuconfig", I choose "none" library include, did it wrong? What should I do to exclude the errers?

Need help,ths!

You will need zlib to build user/mtd-utils/build/mkfs.jffs2.

Make sure you have zlib install in your Linux PC.

hi hippo,

thanks for your help, now I can successfully make the kernel, but when I download and mount the jffs2, there is problem:

-------------------------------------

/> mount -t jffs2 /dev/mtdblock0 /mnt

jffs2: Too few erase blocks (0)

mount: Mounting /dev/mtdblock0 on /mnt failed: Invalid argument

/>

------------------------------------

I see the post before as follow:

----------------------------------------

You need to learn flash programmer before using mtd.

First, resize your cfi flash to 4M base addr 0 ,in sopc builder, and regenerate sof.

Then enable epcs mtd and cfi mtd,

in drivers/mtd/maps/

edit epcs_map.c

CODE

static struct mtd_partition epcs_partitions[] =

{

.name = "sof_kernel",

.size = 0x200000,

.offset = 0x000000,

}

};

static const char *part_probes[] __initdata = {NULL};

edit altera.c

CODE

static struct mtd_partition alteramap_partitions[] = {

{

.name = "romfs/jffs2",

.size = 0x400000,

.offset = 0x000000,

}

};

Rebuild kernel image from the start "make clean", "make linux_hwselect...."....

Follow the wiki,

http://nioswiki.jot.com/wikihome/operating...flashprogrammer (http://nioswiki.jot.com/wikihome/operating...flashprogrammer)

To program sof and zImage to your EPCS.

And erase cfi flash.

----------------------------------------

Did it the problem of epcs_map.c and edit altera.c. I use the EPCS4, which is as large as 512Kbytes.

Should edit the files of epcs_map.c and edit altera.c? How to do it.

Waiting your reply, ths!

Ths again for the bison problem I post before, I download the bison package installed ,then make success, there is no ftp build problems.

[ ] Detect non-CFI AMD/JEDEC-compatible flash chips

Don't detect non-CFI.

And please note, the epcs4 is used to store fpga config, plus kernel image.

So there won't be much space left for jffs2.
