DM6446 USB Fix

Almohanad Fayez

Hi, I've been reading about the DM6446 USB host mode fix in the TI wiki

http://wiki.davincidsp.com/index.php/USB_OTG_on_DaVinci

and I had some questions:

1- Do I really need to change the USB header or can I just use a USB converter? and if i have to change the header can i just change to a type A instead of a mini-A?

2- I wasn't clear of the what replacing R132 and connecting DRVVBUS will do? why is it important and will USB host mode basically not work because of it? maybe it's to support some pin changes with the new USB mini header suggested?

thanks

forgot to say:

In addition to the above questions, would it be enough to just apply the patches and load the new driver?

Hi,

Could ypu provide details of your USB application. By default you should be able to support Host/Device mode operation without any modification to the standard EVM.
