More on this ... It seems that if I reset everything via the telnet interface) that helps; it finds all three TAPs in the chain. Pressing the reset button doesn't suffice, so it's not the SRST. Seems to be TRST or something... Now, I don't *think* that should be required. But if it is required, then it should be automatic. _______________________________________________ Openocd-development mailing list [email protected] https://lists.berlios.de/mailman/listinfo/openocd-development
