Timur,
I did define #define CFG_DDR_SDRAM_CLK_CNTL (DDR_SDRAM_CLK_CNTL_SS_EN | \
DDR_SDRAM_CLK_CNTL_CLK_ADJUST_05) in my code, it doesn't work.
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. Sorry.
