I vaguely recall that some of the early Stellaris boards (like that one!) actually wired up TRST ... other chips don't seem to expose that signal, so it's not wired out of the JTAG adapters' CPLDs either. The "all ones" could indicate that the TAP is still being held in reset ... perhaps via TRST. I suggest you check your reset_config lines against board schematics, and maybe the code for that specific adapter. There are a bunch of Stellaris eval boards, with minor differences in JTAG wiring. I'm not sure which config is right for that board. I use "interface/luminary.cfg" on a different board and it's fine, so I'd expect once you sort out this config issue you'll have no problems. - Dave p.s. I also add "reset_config srst_nogate" to my board's default "reset_config srst_only", but I don't recall that anything would care about that. _______________________________________________ Openocd-development mailing list Openocd-development@lists.berlios.de https://lists.berlios.de/mailman/listinfo/openocd-development
