Hi Jason,

Thank you very much, I changed

static struct mtd_partition mb_auto_8mb[] = {
        { name: "Bootloader", offset: 0x00000000, size:   0x00004000 },
        { name: "Bootargs",   offset: 0x00004000, size:   0x00004000 },
        { name: "MAC",        offset: 0x00008000, size:   0x00004000 },
        { name: "Config",     offset: 0x00010000, size:   0x00010000 },
        { name: "Spare",      offset: 0x0000C000, size:   0x00004000 },
        { name: "Image",      offset: 0x00100000, size:   0x00300000 },
        { name: "JFFS2",      offset: 0x00400000, size:   0x00000000 },
        { name: "Flash",     offset: 0 }
};

To:

static struct mtd_partition mb_auto_8mb[] = {
        { name: "Bootloader", offset: 0x00000000, size:   0x00040000 },
        { name: "Bootargs",   offset: 0x00040000, size:   0x00040000 },
        { name: "MAC",        offset: 0x00080000, size:   0x00040000 },
        { name: "Config",     offset: 0x000C0000, size:   0x00080000 },
        { name: "Spare",      offset: 0x00140000, size:   0x000C0000 },
        { name: "Image",      offset: 0x00200000, size:   0x00300000 },
        { name: "JFFS2",      offset: 0x00500000, size:   0x00300000 },
        { name: "Flash",     offset: 0 }
};

And now the kernel loads without problems.

But i cannot login using: root/uClinux

Can you tell me the correct Password for the root-user?

Where can i set these Settings?

Bye,

Philipp

Hi Pilipp,

There is no problem with your flash physical address. Its the user flash
partition table. The mb_auto.c defines the user desired partition table,
but it may not be aligned for some flashes. It is user's responsibility
to ensure that the partitions are aligned to the flash block/sector
boundaries. e.g. Let say you have a 8MB flash that is constructed by 32
sectors and each sector is 256KB. This means each of the partition size
must be multiple of 256KB.

	Hi Philipp,
	
	This is because the flash map does not match the type of flash
you have.
	The flash maps are located in driver/mtd/maps/mb_auto.c
