Coulda it impact A53 Linux Sys if we enabled M7 core flexCan or LLCE Can jobs to communicate ?

Hi, I worried about bootloader configurations enable Can related intefaces such as  flexCan or LLCE, which potentially impact A53 core linux side ？ How to let it safely enable this scenario ?

Thanks

Thanks directing me to bootloader commuity.

Now the problem is that most of reference booting focus on s32g2 not g3, especially eb ivt configuration, I am not sure whether it is completely same with s32g2 addresses such as dcd address, hse address, app bootloader address, quadspi parameters address, SYS-IMG Pointer, etc. Could you please help me correct them ?   thanks.

Hi,

Thanks for your feedback.

Config Tools will be the one handling the addresses changes, if any. You should not have problems with it (if you have selected the correct platform). We have created IVT binaries with DCD and QSPI parameters for both platforms following the same provided steps, and we did not have issues related to them.

As for the differences, there is an NXP bulletin providing a summary on the impact of migrating from G2 to G3.

Feature Enhancements and Migration from S32G2 to S32G3 Engineering Bulletin (nxp.com)

Please, let us know.

Hi,

The following document talks about some considerations between the bootloader and Linux initializations:

S32G Bootloader Customzition - NXP Community

As specific as the features that you are looking, there is no documentation on this regard. The considerations over what is being initialized and the features being used under one application or the other is to be verified by the developer. We do apologize. 

Please, let us know.
