Due to RF over the air lost, need re-transmission whole image again when do firmware upgrade.
Is there any possible that we can block some code in fixed flash section and just upgrade this section through OTA?
Or any suggestion for improve upgrade stability.
Yes, it is possible. But not simple.
Time to get googling. "incremental" and "patch" would be other good search terms.
Or you could just have a download protocol which can re-start after an interruption
Nothing specifically to do with ARM or Keil.
also "delta"; eg, en.wikipedia.org/.../Delta_update
Hi Andrew
Thanks for your sharing, i will study the Delta update.
As I said, that is just one possible search term - don't forget the others!
I found this os.mbed.com/.../ it seems like what i want, i'm try to understand it.
