USB Type C - advertising a custom SVID on OM13588

[alexfeinman1]

Asking this again, since in 3 weeks no one has responded

The USB PD library provided for K22/PTN5010 used with Kinetis MCUs (OM13588 board) is not documented at all. The code is vast and not very inviting. I need to know how to implement support for a custom SVID aka user alternate mode. I need it to be autonegotiated (PTN5010 is a sink that advertises a user alternate mode).

Thank you

Alex

finding the same thing here - zero documentation for the om13790 pd sdk. painful. crawling through examples to figure out how to do basic stuff.

Dear Alex Freinman,

Sorry for the late replay.

Unfortunately, only the OM13790 - HOST supports the alt mode.

OM13790: USB Type-C Shield Board Gen 2 | NXP 

The demo is usb_pd_alt_mode_dp_host, you can find it in the SDK of the OM13790 board.

Best Regards,

Well, yes and no. Indeed the OM13588 board won't have any DP connectivity or circuitry, but it should still be able to negotiate an alternate mode. You make a good point about the OM13790 SDK - there is a DP sample in it. However it would be even more helpful to see a user alternate mode sample. In the meantime I will be looking at this SDK.

Thank you

Alex
