MPC5674F CPU stress test

[jeonghunkwen]

Hi

I need to run some kind of software on the MPC5674F in order for it to Maximize the current draw and heat generated.

if do you have this document or software, please upload it.

I will wait for your reply.

thank you.

Hi,

we have no such sample code because this is not a common question or requirement.

What plays the biggest role is system frequency. Peripherals adds some current consumption too, of course, but it is not so significant as increasing of the system clock. So, most important point is to configure highest possible system clock.

You can reuse some codes from this example:

https://community.nxp.com/docs/DOC-102744

or from other examples:

https://community.nxp.com/docs/DOC-329623#MPC5674F

And generally, just turn on all peripherals. You can let the DMA to transfer large blocks of data, you can erase some large flash block and so on…

Regards,

Lukas
