I meet SDP problem on 1.2G CPU IMX6Q . In ERR010872 :

How to designs without direct physical access to the SDP port?   It's USB port, add a buffer ?

"A specific mechanism is required to switch the target device into Serial Downloader
mode, in which the SDP can run. NXP can provide details of the mechanism and
guidance on methods and techniques to avoid it"

    what's the "specific mechanism"  ?

   Thanks!
