I have successfully implemented the GDB -> uController side of the equation. Here I have two questions. Is there another way of seeing what GDB sends to the serial port without enabling debug info within GDB ?, i.e. without using the commands : "set debug remote 1" & " set debug serial 1" My second questions relates to the first. With debug info switched on ( "set debug remote 1" & " set debug serial 1"), a single step talks < 1 second to complete, including all the debug info being written to the screen. Yet when I switch off this info the single step time starts at < 1 second but soon mushrooms to ~ 5 seconds. I have tried this on gdb v5 and gdb v5.2.1 with the same results. GDB configured as arm-elf Any ideas?? Thanks, Dave -- http://www.iol.ie
