Hello TI Expert,

HW : SK-AM62

SW : Processor SDK 8.5

I want to check the start time of init processor of Linux. It should be including SPL, U-boot and kernel time.

Can you let me know how to check booting time on SK-AM62?

Best Regards,

Hello,

If you are not looking to be highly accurate, one quick way is to enable timestamp in minicom.

If you connect a USB cable to your EVM and open Minicom to see the boot log, press ‘Ctrl’+’A’ then ‘N’. Then turn on your board and you will see to the left side, the time stamp for each print. Then you could subtract the last-first timestamp to count total boot time from SPL to Linux prompt.

regards,

Judith
