When I increased the FreeRTOS stack from 49K to 160K, the startup time of the SPC5748G increased from more than 300 ms to more than 700 ms（Time to run the startup.s file）. Is there any way to optimize the startup time?</P></BODY></HTML> Thu, 02 Apr 2020 01:47:27 GMT https://community.nxp.com/t5/MPC5xxx/SPC5748G-FreeRTOS-Start-Time/m-p/1047175#M15695 longfeiwang 2020-04-02T01:47:27Z https://community.nxp.com/t5/MPC5xxx/SPC5748G-FreeRTOS-Start-Time/m-p/1047176#M15696 <HTML><HEAD></HEAD><BODY><P>Hello,</P><P></P><P>I guess that your initialization time is binded to RAM init time.</P><P>Maybe FreeRTOS implements some optimization, for compilation, but this you will need to consult with them.</P><P></P><P>It is also worth checking the code to see how the initialization is done and if it can be somehow improved.</P><P></P><P>regards,</P><P>Peter</P></BODY></HTML> Thu, 02 Apr 2020 08:07:32 GMT https://community.nxp.com/t5/MPC5xxx/SPC5748G-FreeRTOS-Start-Time/m-p/1047176#M15696 petervlna 2020-04-02T08:07:32Z https://community.nxp.com/t5/MPC5xxx/SPC5748G-FreeRTOS-Start-Time/m-p/1047177#M15697 <HTML><HEAD></HEAD><BODY><P>FreeRTOS is configed by processer expert.</P></BODY></HTML> Fri, 03 Apr 2020 02:47:41 GMT https://community.nxp.com/t5/MPC5xxx/SPC5748G-FreeRTOS-Start-Time/m-p/1047177#M15697 longfeiwang 2020-04-03T02:47:41Z
