u-boot-1.3.4,which was ported to my board S3C44B0.
U-Boot 1.3.4 is more than a year old - we had 5 official releases since. Please consider U-Boot 1.3.4 unsupporeted and upodate to recent code (U-Boot v2009.08).
now what I got from serial:
U-boot-1.3.4 DRAM:8M FLASH:2M
after tracing functions by using "printf" command,I found the problem was "devlist=NULL". then I went deep,found the function "NewHandle" ,whitch is related to Create empty List. It returned "NULL" ,and the problem is command "calloc".
You misunderstand. "calloc" is not the problem, but just the victim.
any help is appreciated.
Most probably your RAM initalization is broken, and U-Boot crashes when staring to run from RAM.
