Hello,

I am using AM335x evm board for CAN communication.

I need to know at what clock speed AM335x is working.

Because AM335x is taking so much time in conversion of CAN messages.

I need to know if clock can be increased or not.

I am using starterware libraries and modified example to work according to my requirements.

Thanks and regards,

Yash

The main oscillator clock of the AM335x GP EVM is 24MHz.

Hi Biser,

Thank you for your reply.
May I know if I can increase the clock by any method except developing our own board.

Thanks and regards,
Yash

You can change the crystal to 25MHz or 26MHz, but you will also need to change SYSBOOT[15:14] resistor configuration and software modifications may be needed too.
