The memory map should look pretty much like this: 0x0000_0000 0x7fff_ffff DDR 2G 0x8000_0000 0x9fff_ffff PCI MEM 512M 0xc000_0000 0xdfff_ffff Rapid IO 512M 0xe000_0000 0xe00f_ffff CCSR 1M 0xe200_0000 0xe2ff_ffff PCI IO 16M 0xf000_0000 0xf7ff_ffff SDRAM 128M 0xf800_0000 0xf80f_ffff BCSR 1M 0xfe00_0000 0xffff_ffff FLASH (boot bank) 16M 3.

Compilation Assuming you're using BASH shell: export CROSS_COMPILE=your-cross-compile-prefix cd u-boot make distclean make MPC8349ADS_config make 5. Downloading and Flashing Images 5.0 Download over serial line using Kermit: loadb [Drop to kermit: ^\c send <u-boot-bin-image> c ] Or via tftp: tftp 10000 u-boot.bin 5.1 Reflash U-boot Image using U-boot tftp 10000 u-boot.bin protect off fe000000 fe09ffff erase fe000000 fe09ffff cp.b 10000 fe000000 xxxx or cp.b 10000 fe000000 a0000 You might have to supply the correct byte count for 'xxxx' from the TFTP. Maybe a0000 will work too, that corresponds to the erased sectors. 6. Notes
