wolfBoot support for Renesas RX72N

Designed by @Noxifer81

We are excited to announce wolfBoot’s support for the Renesas RX72N. The RX72N MCU is the flagship model of RX series, using a 32-bit RX72N 240 MHz microcontroller.

wolfBoot is a portable secure bootloader solution that offers firmware authentication and firmware update mechanisms. Due to its minimalistic design and tiny HAL API, wolfBoot is completely independent from any OS or bare-metal application.

By adding wolfBoot support for the board, it demonstrates simple secure firmware update by wolfBoot. A sample application v1 is securely updated to v2. Both versions behave the same except displaying its version of v1 or v2. They are compiled by e2Studio and run on the target board. Detailed steps to run the application can be found at GitHub README.

Additionally, you are able to run wolfBoot with Renesas TSIP (Trusted Secure IP) driver, which supports high-speed hardware encryption. You can find the Readme at wolfBoot GitHub.

Current support for Renesas TSIP driver acceleration includes:

  • SHA256/RSA
