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. Jason Schleifer, Philipp, PGR2 wrote: I have 8 MB linear flash, which i selected in menuconfig. This is the address range, when doing an xload in xmd console.

The flash maps are located in driver/mtd/maps/mb_auto.c Jason Schleifer, Philipp, PGR2 wrote: 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 my menuconfig twice - it matches that one from the tutorial by John Williams.
