You should check the PIN mux configuration of McBSP1 FSR/CLKR pins. McB= SP1 on dm3730 have 6 pin configuration. I think the capture should work fine i= f you select the FSX as FSR source, and CLKX as CLKR source. --=20 P=E9ter -- To unsubscribe from this list: send the line "unsubscribe linux-omap" i= n the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
