I look more into using both dimms issue and I see two interesting things.
- With two dimms it never get pass line 1478 - 1500 in spd_sdram.c. It
loops once then hangs.
- If I disable this part (ie break) I get the ERROR: Cannot determine a
common read delay. If I comment out the hang() It returns but it only calculated 768MB of memory.
Only 768MB? Does this mean you are using more than 512MB? As I mentioned earlier, this can't work right now. The TLB setup is for a max. of 512MB.
Please try the attached init.S file. It fixes the issue mentioned by Marc Howard _and_ adds TLB entries for a max. of 1GB of DDR. It will be checked into the official git tree in a few days.
Please let me know if this changes anything.
Best regards, Stefan
