is there any open source bootloader for arm cortex m*?
I have a series of boards (light LED control/ motor control ,...) controlled via CAN/LIN/Ethernet and would like to have a bootloader where certain things are shared:
the crc code, version numbering of the bootloader, a robust protokol to update it. ... may be integrated build/
compile time of bootloader....
Stm32 comes with a bootloader example, but it is very basic. No version numbering ...
Arm mBed OS is open source and may be helpful for you.
Mbed OS is the leading open-source RTOS for the Internet of Things, speeding up the creation and deployment of IoT devices based on Arm processors.
With Mbed OS, you can develop IoT software in C++ with our free online IDE, generate optimized code with Arm C/C++ Compiler and run it on hundreds of hardware platforms.
The Mbed OS stack includes TLS, networking, storage and drivers, and is enhanced by thousands of code examples and libraries.
But this is not a bootloader, but rather a full featured RTOS. It's not the same thing at all
You can check out MCUBoot (https://mcuboot.com) and das u-boot (https://www.denx.de/wiki/U-Boot). Both are open source :)
Hi, as saysKhazAkar U-Boot and mcuboot are good one. But it depends on the board and the way you are booting it.
