Hello,

we are developing our image based on j721s2-evm codebase, after we log in the UART shell ( boot from eMMC ), the uart hang after 3 minutes idle. 

how to modify the system as never sleep/suspend ?

the attached file is all the patches of the kernel.

There are a lot of custom patches that are developed on top of the SDK. Please try with the default SDK and you should observe no such hangs.

If you do observe hangs with default SDK then please report it back to us. We will not be able to debug custom patches.

Best Regards,
