Cortex-M4F MCU Subsystem Development¶

This page provides links to information about a number of more advanced capabilities of the MitySOM-AM62 and Development kit.

Note that the Cortex-M4F is not available on the MitySOM-AM62A.

Tested on Ubuntu 22.04. Later versions may have problems with Code Composer's dependencies.

Installing the development software¶

Note that the version of the SDK used to build M4 projects must match the linux SDK version from TI. If you are using SDK 8 for the main filesystem, you will need to use version 8 of the M4 SDK etc

TI MCU SDK Installation¶

See https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/09_02_01_06/exports/docs/api_guide_am62x/SDK_DOWNLOAD_PAGE.html
OR https://www.ti.com/tool/download/MCU-PLUS-SDK-AM62X/09.02.01.06

• Download the SDK installer and install at below path on your PC

• Windows, C:/ti</li>
• Linux, ${HOME}/ti</li>

*${SDK_INSTALL_PATH} in this user guide refers to the path, including the SDK folder name, where the SDK is installed. Example, in Windows, ${SDK_INSTALL_PATH} will refer to the path C:/ti/mcu_plus_sdk_{soc}_{version}
*You can also browse, download and install the SDK with TI Resource Explorer:https://dev.ti.com/tirex/explore/node?node=A__ANHZpduhqBzZE-IDuTYcYA__am62x-dev-portal__wX8Q.zP__LATEST

Adding the SysConfig Application¶

• The SysConfig download home page is https://www.ti.com/tool/SYSCONFIG

• Download SysConfig 1.20.0 from below direct links,<ul>
• Windows, WINDOWS INSTALLER
• Linux, LINUX INSTALLER

• Install at below path,

• Windows, C:/ti
• Linux, ${HOME}/ti

Code Composer Studio¶

Download the Code Composer Studio™ IDE

Note: It is best to install the SDK, sysconfig, etc before installing CCS so it can detect them automatically.

Install Drivers¶

sudo apt update
sudo apt install libc6-i386 libusb-0.1-4 libgconf-2-4 libncurses5 libpython2.7 libtinfo5
cd <CCS_INSTALL_DIR>/ccs/install_scripts
sudo ./install_drivers.sh
