I was referring to the original tcl/target/lpc1768.cfg from openocd, which still has that statement in its "reset init" sequence. >> It also doesn't remap the Bootloader on Address 0x00000000 >> correctly.

Yes but "reset init" or "reset halt" stop the bootloader before this remapping. >> A bigger issue was Reset configuration: OpenOCDs lpc1768.cfg >> states: "trst_and_srst srst_pulls_trst" which seems to be correct, >> BUT you cannot issue a "reset init" (unless you change the rest config >> to "trst_only").
