If this works try to increase it. Many thanks! Somehow in my testing (probably to try to replicate XC's config) I had put jtag_rclk in my .cfg file. I've replaced it with jtag_khz 30, and I can at least initialise now. Sorry for the misdirection. So, summary: r1932, J-Link V6, XScale IXP422 target. Initialisation works. Now the tcl scripts have moved, I need to work out how to be in the right directory (src/target) to find the XScale debug handler, and the right directory (tcl) for "source [find target/ixp42x.cfg]" to work... _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
