MCU-PLUS-SDK-AM243X: Total resource consumed 35% for a small IPC application of 20K Code

Part Number: MCU-PLUS-SDK-AM243X
Other Parts Discussed in Thread: SYSCONFIG

Hello everyone,

I am developing a safety product (61508 SIL3) which uses a R5F core for black channel and M4F core for safety channel.

I have some questions related to M4F.

1/ As the communication between R5F and M4F use your IPC library, i would like to know if the IPC library is certified?

2/ As M4F core is used as safety channel (safe) in no-rtos, i would like to know if the SDK is certified (our application uses I2C drivers, IPC library, UART and GPIO) ?

3/ i would like to get your feedback about the memory use, for example about a simple demo IPC code, we saw the total resource consumed is 35% for a small application of 20K Code.

From the map file, this is my understanding:

I can see in the map file that the IPC library is around 13Kb.

Thanks

Hi christophe vieville,

Our expert is OOO and will be back on 16th Feb. Please expect some delay in response.

1/ As the communication between R5F and M4F use your IPC library, i would like to know if the IPC library is certified?

Regarding the safety certification, I am yet to consult with the SDK team if they are already certified or the certification is in pipeline.

3/ i would like to get your feedback about the memory use, for example about a simple demo IPC code, we saw the total resource consumed is 35% for a small application of 20K Code.

Seems like, you're taking a memory footprint for the M4 core and yes you'll be seeing this higher usage because the memory available for M4 core is very low, hence the M4 core should only be used to handle things like authentication, crypto etc., and not handle any extra real time things.

Thanks

Yes, it is for the M4, but i am little bit afraid about your answer, we are using as safety isolated core, For a safety application. which will manage safe protocol and safety I/O, not simple task ask you said.

From my point of view you are referring to the M3 and not the M4. I expected more an answer which allow me to reduce the size of the footprint (reducing the stack or the heap for example).

Hi Christophe,

What is this demo IPC code please? Is it Notify example or RpMsg? The reason is, the RpMsg has extra code to handle the VRING memory etc., You cannot simply improve the memory footprint by changing the heap or stack size. The code size has to reduce.

Hi Kowshik,

Yes it the demo code ipc_rpmsg_echo, you can see that in the table.I may have wrong, but from my point of view (you can look in the table), the 35% are:

69392 bytes, which is 20210 bytes of code + the 32768 bytes for the heap + 16384 bytes for the stack.
About the 20210, there is 916 byte of user application, and all others are for sysconfig (512), Dirver lib (7916), nortos (8168), libc (892), clang (1806).
The ring is out of side of this, it is in VRING.

I am pretty sure that we can reduce the heap and the stack, and may be, you could see what takes the biggest size in the driver and nortos to help to understand how it can be reduced.

Also, the question about the size is linked with the question about the sdk certification, because i guess that it will be a different lib, and it is interesting for us to understand the impact on this size.

I would like to get clarification from you, as well, about the M4 that need to be used only for simple application (authentication, crypto, ..), please can you clarify?

Hi Christophe,

Regarding the memory footprints, as a part of safety certification to our drivers we have developed a different interface of our drivers named as "LLD (Low-Level Drivers") which is expected to have much smaller footprint however the timelines for these drivers to release are not yet freezed.

The M4 cores inside our MCU's are generally considered as the security islands, which means they are isolated from the general purpose peripherals and this cores are highly used to perform secure communications / Boots/ enabling crypto access to the Real-time R5 cores etc., However, we do have drivers for M4 core as well for some modules as IPC (this is needed for creating a secure communication between R5 and M4 cores during secure boot applications etc.,) I hope this answers your query on HSM core usage however you can make this core use as general purpose core as well. Please have a look at the page 29 of our TRM that explains the use-case. AM64x /AM243x Processors Silicon Revision 2.0 Texas Instruments Families of Products (ti.com)

Hope this answers your query.
