am3354 boot via SD: spl and u-boot.img not load to DDR.

Other Parts Discussed in Thread: AM3354, TPS65910

hello  everybody:

I have a factory board that boots from the MMC0 interface on the AM3354.


U-BOOT  version uboot-2014-07 from ti.

Power IC: TPS65217C.

I know that  the GP EVM, IDK and EVM SK use a TPS65910 PMIC.   But    here is as not what influence.

I format card as FAT32 FS and copy MLO and u-boot.img to it, and I set boot pins in 11001b state.

SD card is partitioned into 2 partitions.

-  boot partition : MLO , u-boot.img.

- rootfs partition : nothing.

SD card  boot  the  following figure:

it stop at  line 16.

when  i  use  u-boot-2-11.09  and  sd card  boot  is  normal.

I guess that  the spl  file(MLO) should   load  to  SRAM  and  u-boot.img  load  to  DRAM.

By the way,  I  not  use  dtb  file   and  i  not modified  am335x_evm.h  file.

Why will go wrong  at  line  4  and   line 13 to  16 .

 I am trying to fix the problem, but I have no idea Where to start ?

Hope you can give me advice.
