Can't write data into memory location in ARM 66K2H14 EVM kit

Hi,

Hope you are doing good.!!!

Am using a EVM kit with ARM 66K2Hxx. I tried to write some data into the memory location
0x90000000 using c program.I have generated a simple C program and compiled linaro tool chain and followed below commmands.

Compilation process
--------------------

# arm-linux-gnueabihf-gcc -c <filename.c>

# arm-linux-gnueabihf-ld <filename.o> -o <obj.o> -Ttext=0x80000000

# objcopy -I elf32-little <obj.o> -O binary <obj.bin>


Then through "tftp" i loaded the .bin file into the memory location using the below command and then executed,

# tftp 80000000 <obj.bin>
# go 80000000

But when executed ,board hangs .

Please let me know whether the compilation procedure is correct ?

Thanks,

Rajaguru M

    Dear Rajaguru,
    Your compilation procedure seems to be fine but the DDR location.
    The location which you are writiing is DDR3 location where u-boot may run thus it hangs.

    Please use some other DDR3 location.
    Also, you can use "mw.l" and "md.l" u-boot commands to access the DDR3 memory.

    Also with the same build procedure, I would like to put some "printf" for first time to make sure that build procedure is fine.
