Ok, I understand what you mean now and I confirmed what you said:
current code is setting the portsc register after writing to the OTG
viewport.

The MX31 is by default configured for a USB serial phy, so like you
stated we need first to setup portsc to work in ULPI mode and after
that we can read/write the OTG viewport.

Thanks,
