Hello MING XIA,
Please use the following command to deploy SD u-boot
dd if=u-boot-sdcard-2016.09+fslgit-r0.bin of=/dev/sdb bs=512 seek=8
set SW1[1:8] = '00100000', SW2[1] = '0' for SD boot
For programming NOR flash u-boot, I suspect there is problem with RCW on NOR flash to cause the hardware reset problem, please use CodeWarrior JTAG configuration file to override RCW on the target, for details please refer to the section "8.4 Setting up a remote system to use a JTAG configuration file" in C:\Freescale\CW_PA_v10.5.1\PA\Help\PDF\Targeting_PA_Processors.pdf.
For detailed procedure about flash programming, please refer to the document Flash Programmer for CodeWarrior Power Architecture.
Have a great day,
TIC
