OMAP57XX EVM board dra7xx_evm don't support USB overcurrent

Denis Du

I worked on an OMAP57XX board dra7xx_evm , I found the USB port don't support overcurrent, that is it don't report overcurrent when an overcurrent is happening. My questuion is that the OMAP57XX don't support USB overcurrent at all, or just because this dra7xx_evm board didn't connect the USB overcurrent lines.

Hi Denis,

The Chip supports overrcurrent status for non-OTG hosts only. You can check status with this register:

USB_UTMI_OTG_STATUS[10]

If the chip doesn't support it , the board does as well.
