USB OTG driver for OMAP-L138 LCDK

Todd Brandenburg

Other Parts Discussed in Thread: OMAP-L138, OMAPL138

I'm trying to use the USB OTG port on the OMAP-L138 LCDK, using linux SDK. The USB1.1 interface will not work for my application. I'm not a driver expert but after sorting through the linux-3.1.10/arch/arm/mach-davinci/omapl138-hawk.c and various other files it doesn't appear to support OTG. Is there a driver available for the LCDK? If not, is there a driver that would be similar to LCDK that I could start with?

Any assistance would be appreciated.

Thanks,

Todd

Hi Todd,

As per this link http://processors.wiki.ti.com/index.php/L138/C6748_Development_Kit_(LCDK) it states that it supports "USB OTG port (USB 2.0)"

Did you install the starterware which comes along with the board? . If you install the starterware, you will find many USB demo applications under the path:

C:\ti\OMAPL138_StarterWare_1_10_03_03\build\c674x\cgt_ccs\omapl138\lcdkOMAPL138.

I would recommend you to run those demos for a better understanding. It would be easy for you to start from something which already works.
