Part Number: CC1310 Hello
We have reached a point in our project where we lack SRAM space
Since we do not want to change MCU just yet - we are considering using the Sensor Controller SRAM (AUX_RAM) as an extension of the main core SRAM

I am working on a SBP based custom app and i am running out of RAM at link time. I would like to understand more about reducing RAM usage by ICall and profiles. I am including my module size information from the linker's map file below. As you can see…
I want to declare a time_t global variable in that section of the RAM to read and write every second. For that I need to do those steps?:
- Add the linker symbol "AUX_AS_RAM=1" in the Command File Preprocessing.
- Add all the code that is listed in…

Hi Clement,
probably I found the problem…
When my data are too big I have an problem of memory allocation about AUX_RAM. as you can see below:
Instead when the AUX_RAM is disponible, I have:
So, the question is:
HOW CAN I MOVE AUX_RAM -…
Hi,
Exactly, the same applies for the AUX_RAM as RAM. As you mentioned, the AUX_RAM can be leveraged no matter if the CACHE is already used as RAM and/or the configuration of the SNV.
Best regards,
Hey Ammar;
Are you sure that ram have capable of non-volatile storing.
I writed codes below. When I restarted chip, passcode is erased.
#define APP_SERIAL_ADDRESS (0x400E0000) //AUX_RAM 0x400E 0000
#pragma RETAIN(Psw)
#pragma LOCATION(Psw, APP_SERIAL_ADDRESS…
Hi Tim,
I think that the AUX_RAM is not zeroed by HW on reset so you could try using it to save the data that needs to survive reset.

Hi Markel,
The Sensor Controller only uses the AUX_RAM for code. For the CC2640R2F, the AUX_RAM is 2 KB but for the newer CC26x2 (and CC13x2) devices, AUX_RAM is double (4KB). Maybe you have simply confused one for the other?
