Core clock is 180Mhz,Flash Clock is 25.71 Mhz as Processor Expert recommends...&nbsp; I know that it's a high speed clock mode and any flash activities are prohibited in this mode. In oder to solve it ,i have use by&nbsp;CLOCK_SYS_SetConfiguration()&nbsp; with core clock 120Mhz,Flash clock is 24Mhz, before starting my flash driver (like Flash erase,flash program) activities.But&nbsp; any way,i receive Flash ERROR_ACCEER error. It seems like flash driver didn't know about core/flash clock changing....</SPAN></P><P><SPAN style="color: #51626f; background-color: #ffffff;">Please help me.</SPAN></P></BODY></HTML> Tue, 10 Oct 2017 09:34:19 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/KSDSK-v1-3-flash-driver-while-clock-change/m-p/702534#M43172 renka 2017-10-10T09:34:19Z Re: KSDSK v1.3 flash driver while clock change https://community.nxp.com/t5/Kinetis-Microcontrollers/KSDSK-v1-3-flash-driver-while-clock-change/m-p/702535#M43173 <HTML><HEAD></HEAD><BODY><P>Hi</P><P></P><P>Make sure that the processor in in RUN mode and not HSRUN mode. In HSRUN mode it will not work, even if the clocks are slow.</P><P></P><P>Study also the requirement for changing modes and clocks since there are some rules to be observed.</P><P></P><P>Regards</P><P></P><P>Mark</P></BODY></HTML> Tue, 10 Oct 2017 15:04:38 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/KSDSK-v1-3-flash-driver-while-clock-change/m-p/702535#M43173 mjbcswitzerland 2017-10-10T15:04:38Z Re: KSDSK v1.3 flash driver while clock change https://community.nxp.com/t5/Kinetis-Microcontrollers/KSDSK-v1-3-flash-driver-while-clock-change/m-p/702536#M43174 <HTML><HEAD></HEAD><BODY><P>Thank you.</P></BODY></HTML> Sun, 15 Oct 2017 09:33:59 GMT https://community.nxp.com/t5/Kinetis-Microcontrollers/KSDSK-v1-3-flash-driver-while-clock-change/m-p/702536#M43174 renka 2017-10-15T09:33:59Z
