This folder includes the port of mbed OS on the example system of the Cortex-M3
Design Start Eval package. This example is implemented in FPGA on the MPS2+
board. Please check the [mbed page](https://os.mbed.com/platforms/ARM-CM3DS/) of
board. Please check the [Mbed page](https://os.mbed.com/platforms/ARM-CM3DS/) of
this target for more information.
For convenience, this target is called **CM3DS**.

* `ARM` for Arm Compiler version 5
* `GCC_ARM` for GNU Compiler for Arm
* `IAR` for IAR compiler

## Running
Because of the new memory configuration introduced in commit `CM3DS: switch to
larger memories for code and data` it
has become more easy (and portable amoung all compilers) to use `.elf` files
larger memories for code and data`, it
has become easier (and portable amoung all compilers) to use `.elf` files
instead of `.bin`. `.elf` files are now the default for CM3DS projects and only
they will be generated out of the compilation.
For `.elf` files to work, you will need **at least version 2.2.5** of the MPS2+
firmware. You can find firmware version 2.2.6 and instructions on how to put it
in the MPS2+ board [here](https://community.arm.com/processors/designstart/f/discussions/9727/mps2-firmware-for-mbed).
