But I'm a little confused about software development for these devices.<BR />Is it correct that you can use MCUXpresso for the software development of the M7 core in this device, and not for the A53 cores? If so, then I have some questions about that:<BR /><BR />Is it correct that you only can run some OS like Linux on the A53 cores? And that you can not do some bare metal programming on the A53 cores?<BR /><BR />Can I access all peripherals (in a bare metal way) from the M7 core? How to prevent from the Linux side (A53 cores) accessing the peripherals I want to use on the M7?<BR /><BR />Is the development for the M7 using MCUXPresso completely separate from the OS on the A53 cores? If so, how do I communicate between them?<BR /><BR />Does MCUXPresso run on the OS that is running on the A53? Or is it running on some host PC and does it connect by a debugger probe?</P><P>If using MCUXPresso to configure the device and IO pins. Doesn't that conflict with the OS running on the A53 cores?</P><P>I would help me a lot when these questions gets answered. Because now I'm confused how this all should work.

I have two useful resources that will get you familiarized with the M-core development.</P> <P>This is a <A href="https://community.nxp.com/t5/i-MX-Processors/porting-bare-metal-A53-drivers-for-superloop-app-on-i-mx8m-mini/m-p/1521787" target="_self">colleague's thread</A> to a similar question. It's seen that A-cores do need OS and do not support bare-metal, also that MCUXpresso works for M cores but through IAR and ARM's toolchain.</P> <P>Then, we would move to how A-cores and M-cores get along, I'd begin with <A href="https://www.nxp.com/docs/en/application-note/AN13400.pdf" target="_self">AN13400</A>, it's a great example of how peripherals are shared.</P> <P>Cores are communicated through RPMSG and Remoteproc.</P> <P>Plus, to get started with MCUXpresso in i.MX processors, IAR and ARM's examples, please refer to the attached guide.</P> <P>I hope this help,</P> <P>Regards</P> <P>&nbsp;</P> Fri, 26 May 2023 05:20:01 GMT https://community.nxp.com/t5/MCUXpresso-IDE/MCUXpresso-and-i-MX8M-Plus-cores/m-p/1658091#M9002 JosephAtNXP 2023-05-26T05:20:01Z
