A53 boot from M7

[0xEC]

hi everyone,

I have s32g274a board, I need to example or documentation of booting A53 from M7 core. I searched lots of documentations but i just found IPCF example which is not suitable for my case in this application note it performs M7 booting from A53 U-Boot. There is no explicit booting  application to use both M7 and A53 in M7 started and then boot A53 manner.

is there anyone who suffers the same issue and found solution for it?

best,

Hi,

For booting the A53 core from the M7 core, there is an Application Note which details a multicore application. AN13750 provides the different requirements and configurations required to use the provided NXP bootloader for the M7_0 core to start the A53 core. This AN13750 is available under the S32G2 product page (link: S32G2 Safe and Secure Vehicle Network Processor | NXP Semiconductors) under the "Documentation" section.

This AN requires the usage of EB Tresos (configuration steps are provided on regards of the project). We understand that there is no Bootloader project available under S32 Design Studio at this moment.

We do apologize for the inconvenience.

Please, let us know.
