Compiler

CCStudio

This is the official IDE for TI products, the latest is based on the VSCode app

Download url: https://www.ti.com/tool/CCSTUDIO

Linux

The best way is to use the .desktop file to launch the app, the alternative is to run PATH_TO_INSTALL/ccs/theia/ccstudio, but in any case it will fail with the following message:

AppImage: the setuid sandbox is not running as root

To fix it, you can run it as:

PATH_TO_INSTALL/ccs/theia/ccstudio --no-sandbox

You can also add the following apparmor profile under /etc/apparmor.d/ccstudio

abi <abi/4.0>,
include <tunables/global>
profile arduino PATH_TO_INSTALL/ccs/theia/ccstudio flags=(unconfined) {
  userns,
  include if exists <local/ccstudio>
}

And restart apparmor

sudo systemctl restart apparmor

TIP

Generating bin files

For PyOCD, .bin files need to be generated instead of the default .out files, to do that:

1. Right click on Project and click Properties
2. Tools -> Arm Hex Utility
3. Enable checkbox Enable 'Arm Hex Utility'
4. Click on dropdown for Arm Hex Utility
5. Select General Options
6. Enable checkbox Output as bytes rather than target addressing (--byte, -byte)
7. Select Output Format
8. Select Binary (--binary, -b)

Alternative is to edit flags manually and add this:

--byte --diag_wrap=off --binary

Programmer

PyOCD

PyOCD is supported, so any compatible programmer can be used.

I'm using the WeAct MiniDebugger to test it.

Installing PyOCD

(I use a virtual env, but a direct install can also be used)

python3 -m venv ~/pyocd
source ~/pyocd/bin/activate

pip install pyocd

Install the MCU Pack

pyocd pack install MSPM0G3507

Checking the MCU

pyocd cmd -t mspm0g3507 -v

Flash file

pyocd flash -t mspm0g3507 hello-blinky.bin

TIP

BSL / "Unbrick"

Sometimes the MCU can fail to program and it will be "bricked", the easy solution is to start in BSL mode and run the flash command before 10 seconds To enter into BSL you need to:

1. Keep pressed on BSL/A18 button
2. Press NRST button
3. Release NRST button
4. Release BSL/A18 button

There is no other indication about entering this mode, so after the sequence, run the Flash command

Hello World Example

CCStudio

The example at: https://github.com/WeActStudio/WeActStudio.MSPM0G3507CoreBoard/tree/master/Examples/gpio_blink cannot be imported in new versions of CCStudio so the alternative is:

1. File -> Create New Project
2. Device and Board write MSPM0G3507 select the item under Device
3. Select empty_cpp as Project File Name
4. Click on Import
5. Select CCS - TI Arm Clang Compiler
6. Next
7. Project Name gpio_blink
8. Next

The first time it will take some time to download the proper toolchain

9. Right click over empty_cpp.syscfg -> Open with.. -> Text Editor
10. Copy code from: https://github.com/WeActStudio/WeActStudio.MSPM0G3507CoreBoard/blob/master/Examples/gpio_blink/gpio_blink.syscfg
11. Double click over empty_cpp.cpp
12. Copy code from: https://github.com/WeActStudio/WeActStudio.MSPM0G3507CoreBoard/blob/master/Examples/gpio_blink/gpio_blink.c
13. Project -> Build Projects (or Ctrl+b)
14. Refer to Generating bin files section

The example will start blinking the built-in LED every 4 seconds. If you press the BSL/A18 button then it will blink 4x faster, or every second.
