FlashAlgo

Framework for building Arm "FLM" style flash programming algorithms.

Other options

Before you consider adding a flash algo here, you might wish to check if an open source flash algo already exists for your device or a similar device. Many of the FLM flash algos included in CMSIS Device Family Packs (DFPs) come with source code. For instance, the Keil DFPs include sources.

You can download a DFP for your device from the official CMSIS-Pack list: by pack or by part number.

DFPs extract as zips (change the extension). For the DFPs created by Keil, .FLM algos and code are under ./CMSIS/Flash/. Other vendors may have algos in a different folder, and may or may not include source.

Development Setup

Skip any step where a compatible tool already exists

1. Install Python 3.6 or later and make sure it's added to path
2. Install Git and make sure it's added to path
3. Install a supported toolchain:
   1. GNU Arm Embedded
   2. Keil MDK-ARM
4. Install GNU Make.

$ git clone https://github.com/mbedmicro/FlashAlgo
$ python3 -mvenv venv
$ source venv/bin/activate
$ pip install -r requirements.txt

Develop

GCC with Make

1. Update tools and generate project files. This should be done everytime you pull new changes

$ progen build -t make_gcc_arm

Add the project name(s) to the command if you only want to build a limited set of projects. You can list available projects with progen list -f projects.yaml projects.

MDK

$ progen generate -t uvision
$ tools\launch_uvision.bat

Now open the project file for the desired target in .\projectfiles\uvision\<target>\

To change the RAM base address to something other than the default value of 0x20000000, add the argument --blob_start <hex-ram-address> in "Projects ❱ Options ❱ User ❱ After Build/Rebuild section of the µVision project.

Adding a new project

For adding new targets start from template and use these docs...
