Hi igorpadykov,


Processor:IMX281

Linux Kernel version:2.6.35

Linux BSP:L2.6.35_1.1.0_130130_source


I have built imx28_ivt_linux.sb for my custom board.

We are using  VDD 5V only.  Thus  I have define


     #define NO_DCDC_BATT_SOURCE(in power_prep.c)


Successfully booted up from SD.

But stuck at "uncompressing linux"


HTLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLLFLC

PowerPrep start initialize power...

 

Configured for 5v only power source.            Battery powered operation disabled.
