IWR1843: Increase system Heap memory

Part Number: IWR1843
Other Parts Discussed in Thread: IWR6843

Hello,

I am running out of system heap memory and I need to increase it. My starting point was the MRR example which has by default 32*1024 Bytes. However, the iwr1843 has up to 192*1024, no?

I have changed the configuration file as follows:

And I have checked that the linker and memory map have a proper configuration:

The question is that I am not completely sure if I have to do more changes or I will have some memory overlapping issues?

Is there any guide or documentation that I can read to know how to configure the memory layout?

Regards,

Javier

    Hi Javier,

    An expert will comment shortly. In the meantime, can you tell us what you mean by MRR and if this is a project for the DSS or MSS?

    Best,

    Hello Nathan,

    With MRR I mean the Medium Range Radar example, just if you need to take more information about the project configuration.

    Regarding the second question, it is related to the MSS. By the moment it is the only one that I need to increase that memory.

    Regards,

    Javier,

    I do not think there is any specific documentation for this readily available. The best recommendation would be to refer to the documentation on linker files which is included with CCS and to take a look at some of our other demos to see if they use memory configurations similar to what you are looking for. If you take a look at the People Counting Demo on IWR6843, it has what I believe is one of the most aggressive memory configurations (since it overlays some of its code memory with some of its data memory). While IWR6843 and IWR1843 are not identical, they should be very similar.

    Best Regards,

    Hi Alec,

    Many thanks for your recommendation, as I can see the maximum size used in the examples is 40*1024. Therefore, I will use it meanwhile I check other example such as  the one you mention.

    Best regards,

    Javier
