nhatthanh_xp — Fri, 06 Dec 2019 10:30:22 GMT

Dear all,

This is first time I post, So if have any mis-take. Please help me to improve. Thanks.

My question is:

I want to create 3 partition include:
+ Bootloader (1st): support to verify OTA partion and Jump to app
+ OTA1: Application partition as index 1st

+ OTA2: Application partition as index 2st

From bootloader, I can switch between OTA1 and OTA2.

Can I do it?

Thanks,

Thanh Luong

Hi Luong Van Thanh

If you have enough memory for this, yes, this should be possible modifying the linker file and setting protection for the region memories that you want. I would recommend you check the following application note:

Hope this helps
