2010-03-03 05:00:14     USB OTG support in 2009R1 release

Hi,

 

I wanted to know details regarding the USB OTG support in 2009R1 release.

 

We've designed our board with BF527 and are using 2009R1 distrbution, the system works in USB-HOST mode and we are able to plug-in slave devices (provided we set the driver mode to 'USB HOST' during image build) and it also works well as a USB peripheral (when image is built with driver mode set to USB Peripheral). But it does not detect slave devices when we build the image with driver mode set to USB OTG (after enabling power management).

 

I've gone through the following link:

 

  docs.blackfin.uclinux.org/doku.php?id=linux-kernel:drivers:musb&s#usb_otg_support

 

It says OTG mode is not fully supported, but then it again says "cable based switching should work". Does 2009R1 release have  'USB OTG mode' working?

 

Note: We are using the correct cable - USB mini-A ---> BF527 board

 

Thanks

 

Ashish

Can you tell me if support for OTG role mode switching is included in 2010R1?  Looking at the kernel configuration options in 2010R1-RC2, it does not appear that an OTG driver is available (only Host or Peripheral). 

 

Thanks,

 

Derek
