Topic: Questions about wolfBoot for STM32H563 with dual bank update

Hi,
I am interested in wolfBoot for STM32H563, and I have some questions about the dual bank update feature.
1. While the application code update by dual bank method, can the wolfBoot update itself in a power-fail-safe way?
2. While the application code update by dual bank method, can the application update in a power-fail-safe way?
3. How does STM32H563 verify the wolfBoot while reset? by STM32H563's RSS?
Thank you,
Snaku

Re: Questions about wolfBoot for STM32H563 with dual bank update

Hi Snaku,

Thank you for your interest in wolfBoot on the STM32H5 and these excellent questions!

1) This is supported. wolfBoot has two copies (one in each flash bank) and is power fail safe and can be updated
2) Yes this is always true (with or without dual bank)... the application updates are power fail safe.
3) This is handled by ST's OEM-iROT. There are OTP areas that contain root of trust to validate wolfBoot. This area needs a bit of work still and is under development.

You should see an email soon from our business team as we'd love to discuss your project more.

Thanks,
David Garske, wolfSSL
