Is it mandatory to match RTD version between M7_0 Bootloader and M7_0 App?

[Dominic88]

I am preparing a S32G274A bootloader customization, which operates only the M7_0 core. I mainly referenced two documents 'AN13750' and 'S32G_Bootloader_V2-2022.1024_eng.pdf'

I'd like to customize the bootloader to load the prepared M7_0 App(AUTOSAR SWP) with example work(AN13750 - Integration_Reference_Examples_S32G2_2022_06).

However, I have one doubt regarding RTD.

- In AN13750, Bootloader was made based on 'RTD_4.4_3.0.2'

- The prepared M7_0 App image's RTD version is 'ex. RTD_4.4_4.0.2_P04'

Q1. Are bootloaders and apps with different RTD version compatible?

Q2. If not, is there a way to change the example bootloader's RTD version to specific RTD version?

Best Regards,

Dominic.

Hello, @Dominic88 

Thanks for you post.

I suggest using the same RTD during the development.

Regarding to the bootloader and the corresponding M7 application running on same M7_0, since bootloader fully quits and totally switched to the M7_0 application, it may not impact if different RTD used for bootloader and M7_0 application, but again, I suggest using the same RTD during the development work.

It is possible to change the RTD used for the bootloader, you may rebuild the bootloader using different RTD,  but unlike the version that used in the AN, the other version are not verified and tested, there may be issues that need to be debugged during the integration.

For bootloader itself, the version that mentioned in the AN is relatively old, there are newer version for your reference which are based with newer version RTD.
