U-BOOT V2 MX27 boot problem

Hi,
I check out the last U-BOOT V2 code from git yesterday, and start to debug with my new MX27 board, just like MX27ADS. I config the U-BOOT V2 with pcm038 configuration.

I use ADSToolKit Standard V1.3 from freescale to program the bootloader. When I download redboot's binary file, it works. But the U-BOOT binary, it can't work at all.

I checked the code and find that redboot TEXT BASE is 0xa7f00000, but U-BOOT is 0xa0000000. I changed U-BOOT to use 0xa7f00000, it can start some steps. I found it crashed at get_mtab-entry_by_path at fs.c

It seems that mtab is not correct, so e-path never equal with path.

what's wrong with this? I still try to find what's wrong with mtab.

Any kind of hints are welcome.

Regards,
Yanjun Luo.
