Hi all,
My board designed USB0 for host and USB1 for slave. All seems fine in the startup messages. But when I plug in a USB disk, nothing happens. I can see a rising voltage on the D+ pin.
I found that EVM use USB0 for slave and USB1 for host. Is this the reason? if yes, what should I do to let the USB work? if not, what's the reason?
P.S.
I set the usb0_drvvbus and usb1_drvvbus as gpio. Is this OK?
What's the plat_mode stand for in the following message?
[ 0.138763] musb-ti81xx musb-ti81xx: musb0, board_mode=0x13, plat_mode=0x3
[ 0.139068] musb-ti81xx musb-ti81xx: musb1, board_mode=0x13, plat_mode=0x1
Thank you very much.
Lihua
