Issue building bladeRF FPGA (missing Nios II GNU toolchain / nios2-elf-gcc)
Posted: Wed Sep 03, 2025 8:38 pm
I’m attempting to build the bladeRF FPGA image for bladeRF-micro A4 hosted using:
Environment:
• Quartus Prime Lite 20.1 on Ubuntu (VM)
• SoC EDS 20.1 installed under intelFPGA_lite/20.1/nios2eds
The build initializes correctly, generates Qsys systems and PLLs, but fails at the BSP step with:
It looks like Quartus/SoC EDS no longer ships the Nios II GNU toolchain (nios2-elf-gcc). Intel’s old nios2-gnu-toolchain-2020.05-linux.tar.gz links are gone, and I can’t locate a current mirror.
What’s the recommended approach in 2025 to resolve this? Is there an updated/prebuilt Nios II GNU toolchain available for Linux?
