Hello Team.
I am using am335x processor based custom board and using Beaglebone BSP.I am using ti-processor-sdk-linux-am335x-evm-04.01.00.06 and kernel version is 4.9.41.
when I am running htop command 
As soon as i connect musb for taking the ssh of the board it is showing cpu load 100%
Kindly suggest me what can i do to reduce the CPU load.
Rahul,
What usb gadget driver do you use on am335x? Please provide the output of command 'cat /sys/class/udc/musb-hdrc.0/uevent'.
Is the PC running Linux or Windows?
Rahul Chauhan said:after that I am doing ssh of my board on my PC.
ssh root@192.168.7.2
it is taking around 30 second to connect.
Is it always take this long time to connect? Please try the following command on Linux PC to remove the old ssh key entry to see if it solves the issue?
$ ssh-keygen -f "${HOME}/.ssh/known_hosts" -R <am335x board usb0 ip address>
By the way, I tested the same on my AM335x GP EVM with Processor SDK v4.1.0.6 with a Linux PC, but don't see the problem, am335x cpu load is about 5~10%. I used g_ether gadget driver.
How did you load g_ether driver? Following is what I did. Please do the similar and provide the log if you still cannot get usb0 interface.
