We have made ten C6678 board with our own pcb design. Most of them work correct,but three of them failed in DDR3 intialization.
They all failed on the third time to set value to DDR_SDRFC (DDR_SDRFC = 0x00001450) in ddr3_setup_auto_lvl_1333() gel file.
We have tried to set the DDR clock to 1000MHz,but this makes no different.
Here is the log of gel output.
