Hi,
I'd like to know how to implement a dual core LPC4357 firmware upgrade using IAP.
The aim is to upgrade m0 fw through M4, using IAP.

1) I create a *.bin file of the m0 code. Then I'v extrected the bytes needed for the upgrade and I've placed them into M4 code
2) using IAP from M4, I simply program FlashB, starting from sector 0

I tried this procedure but the m0 code doesn't start after the upgrade (and after an LPC4357 reset).

Any sugegstions?

Thanks
Pietro
