Tool/software: Linux
Hello,
We have built a custom AM3358 board and the board layout of eval board was not followed.So with the help of forum and some expertise we are able to perform the software leveling and able to get the optimized timing parameters. After loading these values I was able perform all the DDR tests using CCS. Through code composer studio I was able to connect to board and see the memory , registers, SRAM content everything.
The problem is when I load the same values into ddr_def file , board.c file and generate customized MLO,u-boot.img and load it into MMC0, I have seen that PC(Program Counter) is stuck at 0x402f0440 and not moving further.
Even if we try to load the same into serial port , It was not booting.
The following is the output when I run dss script.
