Jlink and am attempting to debug MQX on the M4 core of a VF6xx with it.  Does anyone have a gdbinit file or instructions for this scenario?  I can only find a gdbinit file for the VF6XX_A5 scenario, and not for the VF6XX_M4 scenario.</P><P></P><P>Thanks.</P></BODY></HTML> Mon, 29 Jun 2015 20:13:26 GMT https://community.nxp.com/t5/Vybrid-Processors/Debugging-M4-with-Segger-JLink/m-p/440757#M4888
