I am developing a device driver for a Video Grabber Cape board for BeagleBone Black and I am facing some problems about AM335x EDMA controller.
As I am developing the driver based in another one of similar board that uses GPMC interface, and this driver only compile in Debian Wheezy 3.8.13-bone79, I need to stay for now in this kernel version, until my driver is OK, when then I will try newer kernel versions.
For accomplish this step, I need the edma_test.c example ( published by Texas Instruments ), but, able to be compiled in Debian 3.8.13. Accordingly with TI E2E forums, the example can work in TI PSP, but, they can’t offer support for Debian. I did a try to compile de edma_test.c that comes with TI PSP, but, it don’t compile in Debian 3.8.13-bone79 or newer kernel from BeagleBone.org.
If someone have this edma_test.c or similar kernel module for AM335x EDMA, compatible with Debian 3.8.13-bone79 and can share it with me, I would apreciate this very much.
Thanks in advance.
