Re: AW: [microblaze-uclinux] Problems with partitions



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.

I have 8 MB linear flash, which i selected in menuconfig.

This is the address range, when doing an xload in xmd console.

(0x22000000-0x227fffff) FLASH_2Mx32 mb_opb

So, do i have to add an offset of 0x22000000 in Line 179 of
driver/mtd/maps/mb_auto.c where the mtd_partition mb_auto_8mb struct
Is defined?

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

	Hello, 

	I managed to bootup linux but i cannot login with root/uClinux 
	I think this is because the creation of flash failed. I checked

John Williams. 

	Thanks, Philipp
