I am using MSP430FR5994

Is there any sample software that accesses 256KB of memory (FRAM) and expands the image memory?

The sample software I currently have accesses FRAM (49KB).

Please let me know the sample software that can access FRAM2 (213KB).

I am using CCS Ver.11

All the example code you can find in https://dev.ti.com/tirex/explore/node?node=AGwOs4KJVcoFm1YCUWwOiw__IOGqZri__LATEST&search=5994

Could you explain what is image memory?

sorry

The explanation was insufficient.

The system I'm developing displays two OLEDs (128*128, 16BIT color).

I'm trying to prepare two sets of double buffers to expand drawing data in the FRAM2 area (213KB).

However, in the sample software provided
I asked because it was access to FRAM (49KB).

Follow this example to write FRAM memory https://dev.ti.com/tirex/explore/node?node=AD3HYYik5.NyMRlyehHKjg__IOGqZri__LATEST&search=5994

For FRAM2 memory access. refer to this doc https://www.ti.com/lit/an/slaa628b/slaa628b.pdf?ts=1660811789895&ref_url=https%253A%252F%252Fwww.google.com%252F

#if defined(__IAR_SYSTEMS_ICC__)
#pragma location = 0x9000
__no_init uint16_t temperatureData[10000];
#elif defined(__TI_COMPILER_VERSION__)
#pragma PERSISTENT(temperatureData)
uint16_t temperatureData[10000] = {0};
//uint16_t temperatureData[16384] = {0};

The above source code is provided
Using FRAM
There are changes in the area.
However, there is no change in the FRAM2 area. Is this area unusable?
