2008-07-17 12:41:56     some troubles with jffs2

Message: 59026   

Hi,

using BF537 , 2008R1-RC8 dist  and an M25P128 Flash.

when i tried to put the jffs2 on my board on the ST M25128 ( 128Mb) i got some probs, the config is as follows;

Partition1: U-Boot.

Partition2: kernel Image.

Partion3: jffs2 fs

I used the default config in the stamp.c file :

#if defined(CONFIG_MTD_M25P80) \

    || defined(CONFIG_MTD_M25P80_MODULE)

static struct mtd_partition bfin_spi_flash_partitions[] = {

    {

        .name = "bootloader",

        .size = 0x00040000,

        .offset = 0,

        .mask_flags = MTD_CAP_ROM

    }, {

        .name = "kernel",

        .size = 0xe0000,

        .offset = 0x40000

    }, {

        .name = "file system",

        .size = 0x6e0000,

        .offset = 0x00120000,

    }

};

I load it like this:

> bootargs=root=/dev/mtdblock2 rw rootfstype=jffs2 earlyprintk=serial,uart0,57600

> eeprom read 1000000 40000 7C0000

kernel loads with those log messages:

bootm

so, what do you think about the above background colored messages ? and what about the M25P128 Flash?

Thank you,

you need to change the '.type' field to match your part in the board resources file

Mike,

You mean that I need just to change it like this:  (.type = "m25p128",) ?

Ok thank you Mike,

but what about the others errors:

mount: mounting devpts on /dev/pts failed

what do those mean?

Message: 59134   

if you disable the devpts filesystem in the kernel, then trying to mount it isnt going to work

i wouldnt bother looking at mtd errors until your mtd's are configured properly

Thank you Mike and sorry to be too late ,

I changed the .type to {.type = "m25p128",} but I get other problems as follow:

New changes to the bfin_spi_flash_partitions[] in order to  align write/read of blocks :

static struct mtd_partition bfin_spi_flash_partitions[] = {

    {

        .name = "bootloader",

        .size = 0x00040000,

        .offset = 0,

        .mask_flags = MTD_CAP_ROM

    }, {

        .name = "kernel",

        .size = 0x100000, //0xe0000

        .offset = 0x40000

    }, {

        .name = "file system",

        .size = 0x300000, //0x6e0000

        .offset = 0x00140000,

    }

};

I flash them:

>tftp 1000 vmImage

>tftp 101000 rootfs.jffs2

>eeprom write 1000 40000 400000

you see that I cannot create any directory on the fs !!

and in the /dev directory I got :

root:/> ls /dev

what do you think?

Ok it's fixed. there was no enough space in the jffs2 partition (3MB), I changed it to (6MB) . Now it works

I'd be wary of a "solution" like this.  It means you're writing to your flash on every boot.

Ian,

what do you mean by :  "writing to your flash on every boot." ?

With the stock /etc/rc file, mdev writes in to /dev which is in flash.   Check the discussion at the URL I pasted for all the details.

Ah ok. Sorry Mike I've not checked SVN in a while.  Any plans for a 2008R2 release?

the next release will be 2008R1.5, but it'll be an update from 2008R1, not from trunk
