We are developing original board with i.MX6D.
Then, I would like to execute USB certification test via JTAG debugger to check the USB signal quality.
Can we set the USB test mode from JTAG debugger without any USB drivers?
If yes, please teach me register's settings to set the USB test mode.
I can execute the USB certification test if U-BOOT or Linux is working.
But, we are early development stage. therefore, we have not finished U-BOOT development.
