Hello,
i am a little it confused i realized thatsome of the pins that are neccesary for ethernet (MIIRXD3,MIIRXD2 ) are also neccesary if you want to Trace data (Trace D1 , Trade D2). Could anyone explain me a workaround hoe to connect ethernet MII Phy and the debugging tool at the same time?
Thanks in advance
cheers manu
'Trace' debug pin connections are only used by, well, TRACE debugging options. So firstly you would have to have a trace-enabled tool (like J-Trace) to even expect to do anything with those pin connections. Secondly, while I have such a tool I have found it 'necessary' only once to dig to that detail level; to find an MQX bug. Most problems are not worth forcing yoursellf to deal quite that deeply into cycle watching. We have used MII here and J-Link tools (restricted to the 10-pin debug header) with no other programming/debug limitations. And of course we only use MII when we are forced into it -- RMII is more efficient.
