Low MPC5744P coremark score.

[ilya_kogan]

I am using the DEVKIT-MPC5744P EVM to evaluate device performance.

I used the eTimer_MPC5744P example to add coremark code. coremark_main is called from the main() just before

the endless while loop. The coremark score is very low - 37.5. Is there something that may not be configured by the example (cache, etc?). System clock is configured for 200MHz, and UART settings confirm this.

Hi, pay attention to following appnote:

https://www.nxp.com/docs/en/application-note/AN4939.pdf 

Cache initialization you may find under the section 3 (Startup code), the most important is to have configured flash controller properly (section 4.1).

Hope it helps
