Are you sure you're executing this code in spd_sdram(): #ifdef CFG_DDR_SDRAM_CLK_CNTL /* Optional platform specific value */ ddr->sdram_clk_cntl = CFG_DDR_SDRAM_CLK_CNTL; #else What I don't understand is that we can > boot up the system using this particular memory but we could not tftp. > Is there any burst mode I can set? Thanks, I really don't know at this point. I've never seen this problem, and tftp isn't particularly demanding, so I don't understand what's happening. My only guess is that your memory is not configured exactly right, so some memory operations work and some don't. Since I'm not expert on DDR, I really can't say what the problem is.
