Is it possible to add any of the Core (R0, R1 ... R13(SP)) registers to the Logical Analyser? Or any global kernel objects?
If you are referring to cortex-m, check this out http://www.keil.com/support/docs/3983.htm
In this way you can define a variable to access these registers and enable at least SWO trace, so that you can add this variable to logic analyzer: www.keil.com/.../uv4_db_dbg_logicanalyzer.htm
