Programming U-Boot

8.1 Programming U-Boot on a Board having no U-Boot

Installed

To program u-boot on a board that has no u-boot installed:

1. Select standalone mode.
2. Connect 110V/220 power to power adapter.
3. Connect RJ45 console line to UART port.
4. Connect network cable into Ethernet port.
5. Connect USB TAP to JTAG port on C29x PCIe.
6. Open the CodeWarrior IDE for Power Architecture, and select P1010 processor with

P1010RDB_core_init.tcl

.

7. Power on board and attach C29x PCIe.
8. Memory download

images/spiimage

, available on C29x PCIe DVD, to 0x10FFFC00.

9. Set the computer to 0x1107f000, and run. When u-boot outputs message on console,

enter u-boot environment.

10. Set u-boot variables, such as

ipaddr

,

serverip

,

ethaddr

, and

eth1addr

.

11. Perform one of the following steps to program NOR/NAND/SPI u-boot:

a. Use the following commands to program NOR u-boot:

tftp 1000000 u-boot.bin

protect off all

erase fff80000 ffffffff

cp.b 1000000 fff80000 80000

b. Use the following commands to program NAND u-boot:

tftp 1000000 u-boot-nand.bin

nand erase 0 80000

nand write 1000000 0 80000

c. Use the following commands to program SPI u-boot:

sf probe 0

sf erase 0 80000

sf write 11000000 0 80000
