MSP430G2955: Remote FW exchange by own code in RAM

Robert Tyrakowski

Part Number: MSP430G2955

Hello,

I have a project with a MSP430G2955 which collect sensor data and feed them into
a local WiFi network. It turned out, that the FW must occasionally be updated or exchanged.

My question is, is there a way to exchange the FW in the code area remotely?
I mean, can the code area programmed by own FW? I know that code can also be executed
from RAM and code area can not be used in this case.I did not find a sufficient decription about it.
If it is possible, is there a documentation or an AP or better a code example which deals with code area programming?

Thank you very much.

Hi Robert,

For this issue, have you try to read image from MCU and do some compare with normal image?

Hi Johnson,

Thanks for your reply. But I think I possibly did not explain my request precisely.

It is not an issue, I need to extend or simply change the FW occasionally due

to different requirements. I simply do not want to reprogram the new FW on-site.

My request is possibly more known as Over-The-Air update.

Meanwhyle I found some docs about OTA for FRAM devices, but this is not what I

need, I think.

No further answer required!

I found ANs and other docs which help me to answer my questions.
