Heya,

I'm trying to boot uClinux 2008R1.5 with rootfs on parallel flash (M29W320EB) on a bf527 EZKit.

But at the time when it's trying to mount the root filesystem I get only read errors:

I flashed uboot, it works. Then I flashed my kernel and my rootfs.jffs2 at their positions according to the partition map. I checked the rootfs by executing 'md.b 0x20130000 0x02' in uboot and got the wanted 85 19.

I edited the partition map in arch/blackfin/mach-bf527/boards/ezkit.c like that:

static struct mtd_partition ezkit_partitions[] = {

    {

        .name       = "Bootloader",

        .size       = 0x30000,

        .offset     = 0,

    }, {

        .name       = "Kernel",

        .size       = 0x100000,

        .offset     = 0x30000,

    }, {

        .name       = "RootFS",

        .size       = 0x400000 - 0x30000 - 0x100000,

        .offset     = 0x30000 + 0x100000 ,

    }

};

It seams as if the read is reading from the wrong address or the returned data is incorrect, although everything is correct on the flash.

Can anyone help me solving this?

Ok, here it is. The end is missing, but it keeps just going on like that and some time later it gives up.

your command line is wrong.  root=mtd2 should not be used, it isnt a block device.  that certainly isnt what the documentation tells you to do.

  docs.blackfin.uclinux.org/doku.php?id=linux-kernel:jffs

also, using mtdparts= on the command line tells the kernel to ignore whatever you put into the board resources ...

Ok, we tried the root=mtd2 option because we had a look into the code and it seemed as if this would be the preferred way. Anyway, when using root=/dev/mtdblock2 as in the documentation the result is the same (see below).

Concerning the mtd command line, we know it overwrites the board specific partition map. We tried this only to be more flexible in testing around with the partition map.

We added some printks (which I removed here) which showed, that ioremap in drivers/mtd/maps/physmap.c: physmap_flash_probe returns 0x20000000 as virtual address. Is that correct?

Ok, I did two things now. I erased the whole flash except for the uboot part and checked it in uboot which says it is all 'ff's. The first read by jffs2 doesn't find its magic bitmask, ok, but it doesn't even find 'ffff' instead. This is the output including my printk (those with !!!!!..)

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

What is interesting here is that after jffs2_flash_read in jffs2_fill_scan_buf the beginning of the buffer contains 0xffff0010 (1st case) and 0xe0010010 (2nd case). The value has been casted as int.

The ffff and e001 bits seem to come from the flash, wheres 0010's source is not clear to me.

The e001 Bytes are those of the jffs2 fs header, directly after the magic bitmask, but in reverse order, but the magic bitmask check is reverse as well, so thats no problem.

So to me it seems, that the function is somehow reading the first 2 bytes from somewhere, but not from the needed position in flash, whereas the next bytes are read from the correct positions.

Any idea on this?

The problem was in the default settings of the memory banks. They are:

#

# EBIU_AMBCTL Control

#

CONFIG_BANK_0=0x7BB0

CONFIG_BANK_1=0x5554

CONFIG_BANK_2=0x7BB0

CONFIG_BANK_3=0xFFC0

When I set CONFIG_BANK_1 also to 0x7BB0 it works. Seems to be a timing problem. I didn't check but assume that bank 3 needs the same setting.

The related file is linux-2.6.x/arch/blackfin/configs/BF527-EZKIT_defconfig and it should contain:

CONFIG_BANK_0=0x7BB0

CONFIG_BANK_2=0x7BB0

CONFIG_BANK_3=0x7BB0

Can someone confirm this?
