p1010 nand_uboot

1.     Build the NAND Boot binary using P1010RDB_NAND_config option on u-boot,

a.      Configure u-boot to build NAND boot binary for platform,

                                                    i.     make ARCH=powerpc CROSS_COMPILE=/opt/freescale/usr/local/gcc-4.5.55-eglibc-2.11.55/powerpc-linux-gnu/bin/powerpc-linux-gnu- *_NAND_config

b.     Build the binary,

                                                    i.     make ARCH=powerpc CROSS_COMPILE=/opt/freescale/usr/local/gcc-4.5.55-eglibc-2.11.55/powerpc-linux-gnu/bin/powerpc-linux-gnu-

                                                  ii.     This will build u-boot-nand.bin

2.     Flash the NAND boot binary on NAND Flash.

a.      For this we can use Code Warrior IDE 10.1 or else the any other bootloader which has NAND Flash driver can be used. For more information on Code warrior based method, please refer to platform BSP user manual. 

            Using other boot method to flash NAND boot binary, steps are given below.

=> tftp 1000000 u-boot-nand.bin

=> nand erase 0 100000

=> nand write 1000000 0 100000

3.     Change the Switch settings for NAND boot.

Change switch settings for NAND Boot

On P1010RDB switch settings for NAND boot are,

SW1.1-SW1.8 = 00001010

SW2.1-SW2.8 = 11011000

SW3.1-SW3.4 = 0111

SW4.1-SW4.4 = 1000

SW6.1-SW6.4 = 1001

Note: Make sure that J11 and J12 Jumpers are mounted on board to disable ECC checking while boot.
