[Kautuk Raj]

Is the ARM GCC toolchain is correctly installed and configured? The error message mentions arm-none-eabi-g++, a part of this toolchain. You can test if it is accessible by running arm-none-eabi-g++ --version in your command line.

[Himanshu]

Hello,

I see that you are encountering the "Generating ELF failed" error in Simulink for PX4 Autopilot.

I faced a similar issue and it was related to the Toolchain Compatibility. Ensure that the Cygwin toolchain version you have downloaded is compatible with the PX4 firmware. The documentation below will help you select the correct Cygwin version:

Setting Up Cygwin Toolchain and Downloading PX4 Source Code - MATLAB & Simulink - MathWorks India

In case the above troubleshooting steps do not fix the issue, you can share the support package version you are using along with the steps you followed before encountering the error.

I hope this helps.

I tried to remove the cgywin toolchain using the GUI and tried to install it again and I have followed the same steps but still I coudnt build the firware
