DRA74x boot fail issue(related to memory and main clock setting)

Hi,

Our processor is DRA74X, with 3.02.00.03 SDK version.

Now the processor can't boot up, there is no any log output after power on.

The memory size is 1GB(4 x 256MB), system main clock source is 19.2Mhz.

Currently, we configure memory setting in the following registers=> 

 

Questions,

1.Is our current setting correct?

2.Is there any other registers we should also check for memory setting?

3.How could i confirm the main clock setting? in which registers?

Regards,

Shawn

    Hi Shawn,

    Is this a custom board which has dra74x SoC on it?
    Could you provide more details on what are the values programmed in the above registers.

    What boot mode are you using? SD card?

    Yes

    So,

    1.Is there any other registers we should also check for memory setting?

    2.How could i confirm the main clock setting? in which registers?

    Shawn,

    The Clock Tree Tool can help you to visualize the clock setup for the SoC:
