MSPM0-SDK: Is ramfunc mandatory when MCU only have one flash bank?

Yiren Wang

Part Number: MSPM0-SDK
Other Parts Discussed in Thread: MSPM0L1105,

I'm developing under MSPM0L1105 which only have one flash bank.

The MSPM0-SDK provide two functions to access flash, one is normal and one is from ram.

I noticed that the function "DL_FlashCTL_executeCommandFromRAM" is in ram section.

For our usage, we have a ram self-test program, it will take us more effort if we need to put a function in ram section.

Can I just use the normal function but not form ram function?

Hi Yiren,

Actually, you can find teo function: Run in RAM and don't run in RAM, just like this one:

Thus you can select which function is suitable for your application.

Thanks!

Can you explain further what's different between these two functions? I'm quiet not sure which function I should use.

Thanks!

Hi Yiren,

Those code run in code will be load into SRAM when MCU power on, thus even we erase the flash, the function still normal due to this code in SRAM.

But if no RAMFUNC, this code will run in Flash, this will encounter some issue, like erase Flash.

Thanks!
