OK, here is time for report what I've done so far.
Firstly, THERE IS a function to download from SD card, but at this moment, there is only 1 way to activate this function, have to be done through telnet from JTAG.
People have MONAHANS is problem with PDA bootloader (PXA312) , then PHONE problem is related to Qualcomm bootloader.
Secondly, there is some functions that I tried on PXA312
sys.option WAITRESET On
data.set 0x40e10414 %long 0x00001841
after this, it will bring you control of MONAHANS
Something important here:
d.s 0x4A00000C %l 0x00000638 ; MSC1 (Static Memory Control Register - SRAM/Async Flash memory)
d.s 0x4A0000A0 %l 0x00000002 ; CSMSADRCFG(CS Config Register)
d.s 0x4A000088 %l 0x0033C919 ; CSADRCFG2(CS Address Config Register) set SCLK cycles address bits and 16 bit device
