Hello,
I am using P1020RM in my current design.
In design, there are Two DDR-3 memory connected with P1020RM.
In earlier design, it was working fine @200MHz clock frequency and below are the hardware setting for 200MHz clock,
- Pin# AJ22, TSEC_1588_PULSE_OUT2 - kept Floating
- Pin# AH21, TSEC_1588_PULSE_OUT1 - kept Floating
- Pin# AG22, TSEC_1588_CLK_OUT - kept Floating
Now we want to increase the clock frequency to 333MHz and for that we made changes from code warrior QCVS for register setting and apply in our u-boot code but It's not working.
Below are the hardware setting for 333MHz clock,
- Pin# AJ22, TSEC_1588_PULSE_OUT2 - kept Low
- Pin# AH21, TSEC_1588_PULSE_OUT1 - kept Low
- Pin# AG22, TSEC_1588_CLK_OUT - kept High
Observation:-
With some different register setting,
- It shows error " D_INT time out. Memory may not work".
With some other different register setting,
- It's not going further after DRAM INIT.
Can any one provide the correct register and hardware setting to work DDR-3 @333MHz clock frequency?
DDR3 Part# AS4C512M8D3A-12BIN
