TDA4VM-Q1: Can boot MCU or DSP from the HLOS?

Shine

Part Number: TDA4VM-Q1

Hello Champs,

After the MCU R5 boot the HLOS on the A72, can it boot MCU or DSP on the HLOS? Or are there some ways to enable or disable the MCU or DSP?

If so, how to realize it?

Thanks
Regards

Hi Shine,

Not sure if I am understanding the question correctly. Can you please elaborate on the bootflow that you are planning to realize?

Hello Parth,

Customer wanted to know if RTOS starts after linux or it starts after R5, C7X, C66X firmware? That is, after booting R5, C7x or C66x, the RTOS begins to boot and then boot the R5, c7x, c66x application?

Another question is that if the R5, C7x and C66x applications share one RTOS or have own RTOS?

Thanks

Shine

Hello Shine,

I am not still very clear on your query.
In general, each core run it's own instance of freeRTOS and these cores can communicate with each other with various ipc mechanisms.

Now there are multiple ways of realizing Linux+RTOS use cases. You can either load firmware on non A72 cores via U-boot or you can boot these cores via SBL and then let SBL load Linux on A72.

Also please refer to teh FAQ https://e2e.ti.com/support/processors-group/processors/f/processors-forum/915474/faq-tda4vm-different-ways-to-load-an-rtos-or-baremetal-application-along-with-linux

This should help with your queries. Let me know if you need any further details

Parth
