We'd like to design a customized board which support 4GB DDR3 RAM.
We use it in Linux BSP 4.1.0, but it seems only 1GB and 2GB DDR3 codes we can refer .
Before I use 4G bits (1CS) *4,total memory is 2G bytes is ok for me.
The DDR3 is H5TQ4G63AFR.
Now my board total memory is 4G bytes, 4G bits (2CS) *8. Per CS is 4ps.
Unfortunately, we got error when we try to use DDR stress tester on 4GB ram board.
error is here:
Beginning stress test
DDR Freq: 528 MHz
t0.1: data is addr test
Address of failure: 0x90000000
Data was: 0x00000200
But pattern should match address
We will attached my detail log and my test tools.
How to design hardware about have eight ddr3 chips,4Gbits(per chip is 256MB*16)*8?
Any ideas can help me to solve this issues?
Thanks a lot.
