Hi,
We've recently received the new EVM2 (Rev G) OMAP boards, and two of them have problems with the USB OTG port (two other boards work OK). We use Windows CE 6.0. All the boards have the same boot loader and the OS image, so there is probably nothing wrong with the software since it works on two devices. Also, the HUBs connected to all the devices are the same, so this is not the cause.
Properly working boards:
P/N:
OMAP-EVM-MB-7-0456,
OMAP-EVM-MB-7-0462.
All the USB devices connected to HUB work without any problems.
Not working boards:
P/N:
OMAP-EVM-MB-7-0410,
OMAP-EVM-MB-7-0412.
The USB devices connected to HUB don't work at all. After connection of the Beagle USB Protocol Analyzer, the LED blinks, and no data is captured.
Are there any hardware problems with the USB port on the EVM2 boards with the low P/N numbers?
Thanks in advance!
Zack
