How can this be? Where to look for the problem?</P><P></P><P>Thanks</P><P>Evgeni</P></BODY></HTML> Fri, 31 Jul 2020 18:58:37 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/FW-in-RAM-Debug-running-speed-is-different-vs-Flash-Release/m-p/1050412#M56926 evgenik 2020-07-31T18:58:37Z Re: FW in RAM Debug running speed is different vs Flash Release https://community.nxp.com/t5/Kinetis-Microcontrollers/FW-in-RAM-Debug-running-speed-is-different-vs-Flash-Release/m-p/1050413#M56927 <HTML><HEAD></HEAD><BODY><P>I found a solution to the problem.
