How to build P1022 SD Boot Image

A P1022DS development system has turned up on my desk, and I'd like to build a u-boot image for it using the current git tree and then boot from SD card. I think I've got most of the parts, but something is missing and it's not working.

 

In the uboot tree:

 

make clean

make P1022DS_36BIT_SDCARD_config

make u-boot.bin

 

Then I cloned git://git.freescale.com/ppc/sdk/boot-format.git and built the sdk-v1.4.x branch.

 

To program the card (Sandisk 4GB SDHC):

 

sudo ./boot_format config_sram_p1022ds.dat ../fs-u-boot-devel/u-boot.bin -sd /dev/sdg

 

The development system arrived booting an older u-boot from 16-bit flash. I changed SW4 bits 5:8 to be 0111, inserted the SD card, and switched on. No output from serial port.

 

What might I be missing?
