In non-AIS mode, we can use UBL for 2nd boot with C6748.
The C6748 in my product is boot from SPI nor flash.
For non-E C6748 chips:
Q1: I'm now using C6748 with AIS mode, is it any way to use UBL for 2nd boot in AIS master mode?
Q2. I want to do remote firmware update with C6748. So if there is no way to use UBL for 2nd boot in AIS master mode, the C6748 program has to get the update image and put it from the 0x00 address of the SPI nor flash. But if there happens to take powerdown in the image writing to flash process, the original would be damaged already and the C6748 would not bootup rightly any more.
So, I think the only way to prevent that is use UBL for 2nd boot, just like the OAD BLE update in CC2541.
But, in AIS mode, I don't know whether UBL is possible, I have thought out any way to do that.
Is there any method that can do image update without any powerdown risk for C6748 in AIS boot mode?
For E C6748 chips:
Q3. The same question with Q1.
Q4. The same question with Q2.
Thank you
