C6457 Question

John Knieriemen

Customer has a problem when generating AECLKOUT from C6457.

Currently, GPIO 15 pull up (high), but we didn’t get the AECLKOUT, please advice what kind of register or settings we need to active the clock.

What else is not working on the C6457?

Can you connect with JTAG and observe registers?

What is the value of the DEVSTAT register, and especially the ECLKINSEL bit?

Do you get other signs of health, such as SYSCLKOUT, if enabled? If not enabled, can you enable it and see a good SYSCLKOUT?
