I built a cape with TS3DV642 to use with beaglebone black. The HDMI switch only works the first time when beaglebone is powered, when I remove the power and connect the power back again it stops working and beaglebone stops getting power and the all the leds on beagle stay off. So I have to disconnect my cape and reconnect the power back on beagle to make it work. And whenever I reconnect my cape and connect the HDMI cables, the power led of beagles flashes. It seems like an ESD is causing my beagle to malfunction. What can be the solution to this problem?
