Hi,
Does a low signal on USB0_VBUS disable the entire USB block? Is this true even at boot. Is there anyway in firmware to use the USB block when USB0_VBUS is low?
Best regards
Anders

Sure, I want the possibility to disable the USB block, from the HW. There should not be a way in FW to surpass this disabling. This should also be true for the USB block during boot.
I there a possibility to use USB0_VBUS in this way?

Hi Andres,
No, USB0_VBUS pin doesn't control the enabling/disabling the USB module, it only indicates how the controller should operate. It is the power domain and PLLs which control it.
What software do you use on AM6411? If it is Linux, I could provide more details on how to disable it in U-Boot and Linux.
