A sentence in readme file

Hi,

Several example readme files for imx95lpd5evk19 board have this sentence:

"Please note this application can't support running with Linux BSP!"

Could you please explain why these Cortex M7 example apps cannot run simultaneously with Linux in Cortex A55?

Re: A sentence in readme file

Hello @jukka1 

Hope you are doing very well.

The warning does not mean the Cortex-M7 cannot run simultaneously with Linux on the i.MX95.

The i.MX95 supports heterogeneous operation with Linux on Cortex-A55 and firmware on Cortex-M7.

However, these SDK examples were developed as standalone demonstrations and assume exclusive ownership of peripherals, clocks, pins, and DMA resources.

When Linux is running, the same resources may already be assigned to Linux drivers, which can lead to conflicts. Therefore the examples are not validated for concurrent execution with the Linux BSP unless the system is properly configured in the System Manager.

Best regards,

Salas.

Hello Salas,

Thanks, I am doing very well. I hope that you are too.

OK, then do you have such M7 examples, which have the proper configuration for the System Manager, and are validated for concurrent execution with the Linux BSP?
I am especially interested in examples for lpi2c/interrupt_b2b_transfer and lpspi/interrupt_b2b_transfer.

BR,

jukka
