Disable VLE assembly

jordancyre — Tue, 18 May 2021 13:28:47 GMT

I'm trying to find a way to disable VLE instructions when compiling my program. I found this thread and tried the solution but it didn't work. S32DS: How to force non-vle build for the entire p... - NXP Community

My command line pattern looks like this: `${COMMAND} ${FLAGS}-mno-vle ${OUTPUT_FLAG} ${OUTPUT_PREFIX}${OUTPUT} ${INPUTS}`

I've attached what my assembly looks like.

I'm really new at all of this so i ask you patience if I don't understand right away. End goal is to use only non-VLE instructions.

Hi, could you specify version of S32 Design Studio?

I have tried this and it works to me.

${COMMAND} ${FLAGS} -c -mno-vle ${OUTPUT_FLAG} ${OUTPUT_PREFIX}${OUTPUT} ${INPUTS}

In the DS, you may see example code:

Turns out my devkit likely doesn't support non-VLE instructions.

I'm using the MPC5748G and the most recent version of S32DS.

Sure, you haven't specify the used MCU.

The only MPC57xx devices supporting BookE instruction set is MPC5777C or MPC5775B/E. All others are VLE only.

Hi,

Adding just my two cents...

see the example below:
