I dug out my old Beagleboard and added an SPI registration to the dts. This was the closest hardware that I had to the N900's processor. What is the version of the gcc compiler you are using and where did you get it from? For instance, I am using a 4.9.1 compiler that I built using Yocto. Also are you using devicetree or the old board file board-rx51.c? -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
