mx287 init gpio failure

I try to use the MFG tool to burn my board, but every time, the tool stops working when kernel tries to initialize gpio( through calling function mx28_gpio_init ),

So I print several trace in the function call process, and I find every time it stops in for loop( at this time, port->id is 4, namely the last bank, and the loop index i value is 27) in function mxs_add_gpio_port.

The kernel version is 2.6.35.3, and MFG tool is 1.6.2.055.

By the way, my board only has VDD5V power, so I enable the macro NO_DCDC_BATT_SOURCE in power_prep.c( in MFG tool source). I don't know if VDD_LI-ION
pin has something to do with the gpio initialization failure.

 

Anyone can help?  Thanks in advance!
