Hi Timur, Sorry, I haven't read your email until today. The command I used is
tftp 4000000 file_name
I met this problem only when I used one particular brand memory, when tftp, it is very slow and sometime it time-out, sometimes it throws exception. When I change to other brand DDR2 memory, it works fine. I want to know is this a memory problem or setting problem or boot code problem? By the way, I used spd setting and manual setting, Both don't work. Thanks
Try adding this to your board config file:
#define CFG_DDR_SDRAM_CLK_CNTL (DDR_SDRAM_CLK_CNTL_SS_EN | \ DDR_SDRAM_CLK_CNTL_CLK_ADJUST_05)
On some 834x systems, CFG_DDR_SDRAM_CLK_CNTL needs to be defined but the header files don't define it.
