Installing required packages

Download and install TI CLANG Compiler Toolchain:

$ cd /tmp
$ wget https://dr-download.ti.com/software-development/ide-configuration-compiler-or-debugger/MD-ayxs93eZNN/2.1.2.LTS/ti_cgt_armllvm_2.1.2.LTS_linux-x64_installer.bin
$ chmod +x ti_cgt_armllvm_2.1.2.LTS_linux-x64_installer.bin
$ ./ti_cgt_armllvm_2.1.2.LTS_linux-x64_installer.bin and install to ~/ti/ti-cgt-armllvm_2.1.2.LTS
$ rm ti_cgt_armllvm_2.1.2.LTS_linux-x64_installer.bin

Download MCU-PLUS-SDK for the SOM:

$ mkdir ~/mcu-plus-sdk-am62x

Documentation

Original TI documentation is available at https://software-dl.ti.com/mcu-plus-sdk/esd/AM62X/08.06.00.18/exports/docs/api_guide_am62x/EXAMPLES.html.
Available also locally at ~/mcu-plus-sdk-am62x/docs/api_guide_am62x/index.html.
Available also starting documentation server running "cd ~/mcu-plus-sdk-am62x" "python3 -m http.server 8080 &" and then open web browser to "http://<ip where documentation server is running>:8080/docs/api_guide_am62x/index.html"

Demos pins for M4F core

Default M4F pins used by the demos are:

Function SoC balls VAR-SOM-AM62 pins Symphony pins Notes
UART2 RXD/TXD R24/R25 J1.115/J1.171 J18.9 / J18.7 The UART2 is not an instance from the MCU domain so only the polling mode is supported.
To more details: Accessing main and wakeup domain peripherals from MCU domain

Don't use /dev/ttyS2 from linux while running M4F examples to avoid conflicts.
