Hi,

What processor is that? What is the u-boot version? Have you checked whether the WDT is enabled when you try to write to it?

thank you for reply,

my processor is AM3352,and u-boot version is u-boot-2013.01.01-psp06.00.00.00, WDT code is default in uboot,I don't change it.
now I have two questions:
1. I use non-muxed (norflash)mode, Which uboot version supports Fast External Booting by default?
2. I 'sure that hardware is no problem . If I use the present u-boot version, Which parts of the software I want to Modify.

Hi,

Fast External Booting (NOR BOOT) should be enabled in u-boot in latest SDK.
You can check include/configs/am335x_evm.h and arch/arm/cpu/armv7/am33xx/board.c and gpmc_init() function in board/ti/am335x/board.c.

Also note that your sysboot should be configured appropriately, see Initialization chapter in AM3352 TRM.

Best Regards,
Yordan
