Hi
Our customer wants to implement OTA upgrade in the way of AB SWAP, but since MCU is S32K116, I wonder whether it is feasible? According to the data, S32K146/148 can implement OTA upgrade of AB SWAP, because only these two types of partition FLASH can Read while Write?
Solved! Go to Solution.
Hi,
you can take a look at this application note which describes it in detail:
https://www.nxp.com/docs/en/application-note/AN12323.pdf
https://www.nxp.com/docs/en/application-note-software/AN12323SW.zip
It is possible to implement AB SWAP also on S32K116/118/142/144 devices. However, there's a limitation that your application cannot run during the update because there's only one Pflash block (read partition).
S32K146/148 has two or three Pflash blocks, so it's possible to run your application during the update.
The application note contains SW examples for both options - there are projects for S32K144 and S32K146.
Regards,
Lukas
