Implementing SWD over a Type A to C USB cable

[Josh]

Hi,

I want to implement SWD (and potentially UART lines) over a type A to C USB cable to talk to the NRF52832 on our board.

Currently, we only want to sink power only with no USB data. We also don't need to pass USB spec, as we are just using the receptacle for nice ID.

Does anyone have any idea of what 5-6 lines would be safe to pass through SWD and UART lines? I was thinking to use the SBU lines plus D+/D- (maybe even the SS Tx lines on the UFP side) but I am not sure how it would work if they plug it into a computer port.

Thanks!

I think I might have misunderstood your initial post. You can use any of the lines in the plug for any purposes you wish, as long as you meet the connector electrical specification. But if anybody accidentally plugs your type A connector into a computer you might destroy the computer and/or the board - We cannot speculate about this or make any guarantees if you proceed to break the standard.
