Please start with the latest kernel. Upgrade U-Boot as well if you have a way to recover if the new image doesn't work (e.g. a BDI). You don't need the bootwrapper for the main serial driver to work. You may need some board-specific pin/port init, though at least the serial port that U-Boot uses should already be set up, assuming it worked in U-Boot of course. :-) If it still doesn't work after switching to a current kernel, try dumping CPM registers, instrumenting the driver, etc. to see what's going on. -Scott _______________________________________________ Linuxppc-dev mailing list Linuxppc-dev@lists.ozlabs.org https://lists.ozlabs.org/listinfo/linuxppc-dev
