Arun, Thanks, it's good to hear not only me having this problem ;). So what is the current status of your osk driver? What tree do you use, what extra patches do you apply to make it actually working? --------------------------- After all, could someone please give me an advise, what tree, even with buggy omap1510 mcbsp/dsp support, should I base my work on for best results? Omap? Sound? Mainline? I mean not only easy getting the driver working, but also giving it the best possible path into the mainline.
