OMAP 3430 and ISP1504A USB support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi all,

I have an EVM board with an OMAP 3430 connected to a ISP1504A OTG chips which has a mini-AB plug-in. I tried to put the 1504A into host mode and would like to see the powering (and detection) of a connected USB device. We check the ID line which seems to be grounded.

The kernel is Linux version 2.6.22.1-omap1 ES2. I enabled the CONFIG_USB_MUSB_OTG  option and I saw the usb0 created. However the transceiver was not in host mode. How could I put it into host mode?

According to the specs of the ISP1504A, I have enable the ID_PULLUP regiser bit to logic 1. I am wondering where should I check to see that the registers are set properly with the MUSB drivers.

Your help is appreciated and thanks in advance,
