In +this example to program the NAND we assume that an SD card has been +inserted with the files to write in the first SD slot and that mtdparts +have been configured correctly for the board. As a time saving measure we +load MLO into memory in one location, copy it into the three locatations +that the ROM checks for additional valid copies, then load U-Boot into +memory. We then write that whole section of memory to NAND. + +U-Boot # mmc rescan +U-Boot # env default -f -a +U-Boot # nand erase.chip +U-Boot # saveenv +U-Boot # load mmc 0 81000000 MLO +U-Boot # cp.b 81000000 81020000 20000 +U-Boot # cp.b 81000000 81040000 20000 +U-Boot # cp.b 81000000 81060000 20000 +U-Boot # load mmc 0 81080000 u-boot.img +U-Boot # nand write 81000000 0 260000 +U-Boot # load mmc 0 ${loadaddr} uImage +U-Boot # nand write ${loadaddr} kernel 500000 Falcon Mode =========== |
