ARM: Can't connect to TLE986x with ULINK2
Information in this knowledgebase article applies to:
I try to connect with the debugger to an Infineon TLE986x device using an ULINK2. But this does not work. I always get a "SWD Communication Error". What is the problem?
The device has Serial Wire (SW) debug only. But this is not
selected by default. So just trying to connect in SW mode fails.
To switch the debug interface to SW mode, make sure the SWJ
switch is checked. With that the debugger executes a special
sequence, that switches to the SW interface, so that later the
debugger can connect via SW.
