Hi Experts,

How to enable all the debug prints in the USB modules and drivers ?

I am using Am335x EVMSK SDK 7.0

Hi,

You can use the printk() function, where you need to print a debug message.

Hi Yordan,

Can I enable all default dev_dbg prints at once instead of enabling prints for individual files.

The aim is to see the sequence the USB stack is getting operated.

Yes, you can do that by setting CONFIG_DYNAMIC_DEBUG=y in your defconfig file.

Or definde DEBUG at the beginning of the driver file.

Best Regards,

Yordan
