Some functions played from RAM take much less time than from Flash (this is a fact). I transferred critical functions to RAM. After that, the code began to work as quickly in the Release as in Debug mode.</P></BODY></HTML> Mon, 03 Aug 2020 11:54:51 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/FW-in-RAM-Debug-running-speed-is-different-vs-Flash-Release/m-p/1050413#M56927 evgenik 2020-08-03T11:54:51Z
