Hi Kemal,

I have done the above steps and then realised the boot process stops at this function
dpll_params *get_dpll_ddr_params(void)

any workarounds ? it ends in the else in that if else statement in the function and returns null.

after i do that

Hi Kemal,

I tried to load the memory usings a jtag (usb100v2 ) but unfortunately i get a message saying load failed. the load start address is 0x402f0400. when i tested the target config i got a success. what could be going wrong ??

If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.1.641.0)

you can see my console messages above.

what am i doing wrong??

Can't find a source file at "arch/arm/cpu/armv7/start.S" 
Locate the file or edit the source lookup path to include its location.

to add further to my troubles start.o is missing in my arch/arm/cpu/armv7 folder thats what my debugging shows so far ... any idea??
