TDA4VM: Data Structures for Mailbox IPC

Hi Danilo,

Please provide additional clarifications as to what you are looking for. What OS are you looking at - the drivers and structures are different between say Linux and RTOS.

Hi Suman,

Thank you for your response. Here is our customer's feedback.

We are using TMS570LC43x 16/32-Bit RISC Flash
Microcontroller -- 2 A72 and 6 r5f cores with a Yocto (Arago?) Linux build running on the Island.

Regards,

Danilo

Hi Danilo,

Do they need the data on the A72 Linux-side or the R5F RTOS-side?

Suman

Hi Suman,

Our customer confirmed that they need the data structures for both the A72 and r5f sides.

Danilo

Hi Suman,

May I request an update to our customer's inquiry.

Danilo

Danilo,

Sorry for the delayed response.

Can you please clarify that this question is for TDA4VM? Your statement here is very confusing.

Are you directly supporting the customer and if yes, can you please share the SDK version and the variant details?

Hi Karthik,

According to our customer,

Sorry for the confusion. We are using TI Linux SDK Version: 08.02.00.01-- we will put the chip on our custom board, but currently we are using J721EXCP01EVM

Hi Danilo,

Is the question about Mailbox data structures or the h/w mailbox assignments used between different processors? The Mailbox accesses in software are all controlled through the respective drivers on each OS, and users would not have to deal with them directly. So, I am not clear on what is the end goal here - is the customer trying to understand the drivers on each side?
