T4240 memory controller stuck when configure as 64bit

[dhanasekaran]

Hi everyone!

In out custom board we use T4240 with 6GB of Discrete dram which connected with DDR controllers as 4GB(DDRC1) and 2GB(DDRC2). By using SPD values I init Dram as 64bit DDRC1 and 32 bit for DDRC2. I get stuck in Uboot but when I changed it to 32bit for both DDRC it work so only 4GB of memory only detected out of 6GB. 

My configuration for 800mhz   ddr clock

Did you try to enable single 64-bit DDRC1? Does it work?

Hi Bulat

It is solved by adjusting write leveling parameters using code Warrier QCVS Tool.

Thanks for the reply.
