SPC5748G FreeRTOS Start Time

[longfeiwang]

I use FreeRTOS in SPC5748G， but I found a problem. 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?

Hello,

I guess that your initialization time is binded to RAM init time.

Maybe FreeRTOS implements some optimization, for compilation, but this you will need to consult with them.

It is also worth checking the code to see how the initialization is done and if it can be somehow improved.

regards,

Peter
