Hello TI,
I found ddr3 initialize problem from my new designed board when use XDS560v2(usb) in CCS v5.1.0 to load "Ti816x_ddr.gel".
This file from ti wiki "DM816x C6A816x AM389x DDR3 Init".
I've checked that the followed code cause failed.
WR_MEM_32(CM_DEFAULT_DMM_CLKCTRL, 0x2); /*Enable DMM clock Clock*/
while(RD_MEM_32(CM_DEFAULT_DMM_CLKCTRL)!=0x2); /*Poll for Module is functional*/
I also check that if I comment these code, initialization still failed.
My board use 2pcs DDR3-1600(MT41J128M16HA-125IT), the hardware config is emif0: 2x(256Mbyte), CPU is C6A8168ACYG.
If you have any idea, please help me.
CCS output infor as follows:
