Airbag Reference Demonstrator porting APR software to MPC5602P platform

[roger_liu]

I downloaded the demo software package of the RDAIRBAGPSI5 reference from https://community.nxp.com/t5/NXP-Designs-Knowledge-Base/RDAIRBAGPSI5-Airbag-Reference-Platform/ta-p/... and used the Airbag Evaluation Platform。 I find the  Airbag Evaluation Platform use MPC5602P, but the software used MPC5604P. so I porting APR software to MPC5602P platform. when I use CodeWarrior 11.1 to build, I find some warning eg:

Hi Roger,

Please make sure you have correctly ported also linker command file (.lcf file).

E.g ".CstHAL" section is not defined at all so it is placed to an available memory which might not be intended.

Hope it helps.

Hello,

Documentation is on the web page you have posted:

https://community.nxp.com/t5/NXP-Designs-Knowledge-Base/RDAIRBAGPSI5-Airbag-Reference-Platform/ta-p/...

SW can be provided under NDA, but it require valid NDA and it is provided via our support ticket system at NXP.com

So for SW please submit NDA request if you don't have one already and also separate ticket for SW package.

Best regards,

Peter

Hello,

Those are just warnings. Nothing to be worried about as I see your elf was build.

Do the application running?

Warnings are be caused by different memory sizes between linkers for MPC5604 and 02, so make sure your code fit to sections sizes in linker to get rid of the warnings.

Best regards,

Peter
