The set_mode_X() HIL functions need to support returning an error if hardware does not support that mode or if the implementation cannot put the hardware in to that mode at that time. See for an example where panic is used instead of returning an error https://github.com/tock/tock/pull/2629/files.
In PROTECTED mode, the MPU is used to map regions of memory to supervisor- and/or user-accessible memory. Currently, that algorithm is very simple: The entire address range is made accessible in supervisor mode; a single MPU region is used to enable user-mode access in each user memory region.
Each MPU region must bit both of a power-of-two size and with an alignment in memory equal to the si
Customizable Bootloader for STM32 microcontrollers. This example demonstrates how to perform in-application-programming of a firmware located on an external SD card with FAT32 file system.
PikaScript is an ultra lightweight Python engine with zero dependencies and zero configuration, that can run with 4KB of RAM (such as STM32G030C8 and STM32F103C8), and very easy to deploy and expand.
