Dear hermann > Is there any documentation and how can a user know about it? "Ecovec board" which I and Guennadi were talking about is an evaluation board. If you buy this board, you can find DVD including manual in its box. Please check ${DVD}/hardware/user's_manual/eng/rej10j2027-0101_R0P7724LC001121RL_um_1.03.pdf "dip-switch settings" is wrote in 3.4 "Switch Specification" If you don't have this board, but have kernel source code, you can watch explain comment on top of ${LINUX}/arch/sh/boards/mach-ecovec24/setup.c Best regards -- Kuninori Morimoto -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
