Build error: address 0x200969e0 of ../bin/teensy41/LedBlinker.elf section `.bss' is not within region `DTCM' #22

Any suggestion on how to resolve this issue? Looks like it maybe related to board memory size. Not really sure the best way to address this issue

Hello,

Any memory related issues can be solved by using custom F' configurations. After the OSAL refactoring and other enhancements within the newer releases of F Prime, the default configuration is no longer suitable for most Arduino-based microcontrollers.

If you recreate the LedBlinker deployment, I updated the cookiecutter to include the bare minimum configuration constants that will reduce the memory consumption of the deployment. Alternatively, you can copy this entire config/ directory into your project. Don't forget to modify your settings.ini file to point to the new configuration directory:

config_directory: ./config

./config is the filepath relative to where the project root directory is. If the directory is in your LedBlinker deployment, the filepath would be ./LedBlinker/config

Also, F Prime v3.5.0 was only tested to work on boards with at least 32 KB of RAM. The Arduino UNO only has 2 KB of SRAM which is insufficient for F Prime. The teensy41 deployment is built for the PJRC Teensy 4.1 Microcontroller. You can view the list of boards that successfully deployed F Prime here.
