Other Parts Discussed in Thread: TCI6638K2K
Hi all,
On my custom board, there are four MT41J128M16JT-15E connected to DDR3A and also four MT41J128M16JT-15E connected to DDR3B.
When I load the GEL with version 'TCI6638K2K GEL file Ver is 1.60000002' xtcievmk2x_DDR.gel
I find that the function ddr3A_64bit_DDR1066_setup has be stuck at here
do {
read_val = DDR3A_PGSR0;
} while ((read_val&0x00000001) != 0x00000001);
And a registers snippet is showed as
What's the problem?

Hi Titusrathinaraj,
I mean that the DDR3 initialization progress has been stuck at here
do {
read_val = DDR3A_PGSR0;
} while ((read_val&0x00000001) != 0x00000001);
It polled PGSR0.IDONE bit.
And then I checked the PIR register like this
Its value is 0x00000000, so I think the DDR3 PHY didn't work.
So then I checked the DDR3 voltage and clock. The voltage 1.5V and 0.75V reference are OK. And the DDR3 input clock 100MHz is OK also.
So I have no idea about how to debug further. Could you help me?

Hi SenthilKumar,
In the doc Keystone II DDR3 Initialization,
it told me that this IDONE poll step should not be omitted.
If I comment this step, then I met the problem like this
