JTAG debugging on FastIO 's

Started by Sagaert Johan April 15, 2006
hi

I use ULINK with keil eval.
When i debug code to toggle pins using fast io, the code works as expected
in run mode, but when single stepping the pins do not follow the values they
should take.
Has this anything to do the way fastio connects to the internal bus, or is
this a ULINK jtag bug ?

I was doing this with an LPC2103 , maybe someone can try to simulate this
on another JTAG device debugger .
