I am trying to program the Nexys A7-100T. I am brand new to this. I am a computer engineering student, trying to get a head start for next Falls class in SoC Design. This is the same FPGA we are using. I am following the RVfpga tutorial from Imagination University. I am running the Blinky.s example. I followed all of the steps in the tutorial. When I build, I get these errors. I am unclear because I call defsym correctly. Below is my CMakeLists.txt file and the terminal output for the error.

I am on Windows 11 64bit. I am using VSCode with Catapult Studio SDK 2024, Ninja, CMake, Catapult Studio Extension. I am using the riscv64-img-elf-as ASM Compiler and Visual Studio C Compiler. Going into Catapult Studio Configure Platform, I can program the FPGA and make the 7-segment LEDs blink and the auto-on states turn off, so something is happening. I just cant get this example to build. This is the same errors I get on all of the examples. I am sure its some stupid little thing I am missing because this is new to me. I tried running this through chatGPT and it said to try -D instead of –defsym … I get the same error.

The Imagination University recommended reverting to an older verison of Catapult Studio SDK, but when I do that, it disables the VSCode extensions and there is no 1.9.1 or non-2024 version of Catapult Studio in VSCode.

Thanks!

I am new to this so I am looking for help. I used ChatGPT and tried basically everything it recommended, and it didn’t help.
