IPRO RISC-V Toolchain

RISC-V GCC cross-compiler (riscv64-unknown-elf-) for building IPRO SDK firmware for IPRO7, IPRO7AI and IPRO6S: GCC, binutils, GDB and newlib with the rv32imafc / ilp32f libraries the SDK builds with.

Which version. IPRO SDK V2.x is built with GCC 14: use 14.2.1. IPRO SDK 1.2.1 pairs with 13.1.1.

On Windows, IPRO SDK Online Setup still installs 13.1.1 (Full environment) and prepares the SDK for it. The Windows 14.2.1 build names the IPRO7 tuning model ipro-7-series instead of intelpro-ipro7 (the generated code is the same). IPRO SDK V2.2.0 looks only for intelpro-ipro7, so with the Windows 14.2.1 build it compiles with the standard RISC-V options, without the IPRO7 DSP extensions; for V2.2.0 with the DSP extensions on Windows, use 13.1.1.

Windows

The steps below install 14.2.1. For 13.1.1, use IPRO-toolchain-win32-13.1.1-20230713.zip (SHA-256 3D37453878F1CA336FF76272FE254CC7357D28C3E0CDDA77C7F3647E0B85B286, first line of --version ends with 13.1.1 20230713) in the same steps.

1. Download IPRO-toolchain-win32-14.2.1-20240816.zip (409 MB).

2. In PowerShell, in the download folder, check the file:

   (Get-FileHash .\IPRO-toolchain-win32-14.2.1-20240816.zip -Algorithm SHA256).Hash

   You should see B6880D1144FF88B7137B831EE2D623217A7837917BA33409B65DCB66821A427A.

3. Both versions extract to the same folder, C:\IPRO\toolchain\riscv_ipro7_win32. If it already exists (an earlier toolchain), rename it first, for example:

   Rename-Item C:\IPRO\toolchain\riscv_ipro7_win32 riscv_ipro7_win32_old

4. Extract the file to C:\IPRO\toolchain:

   Expand-Archive .\IPRO-toolchain-win32-14.2.1-20240816.zip -DestinationPath C:\IPRO\toolchain

5. Check it:

   C:\IPRO\toolchain\riscv_ipro7_win32\bin\riscv64-unknown-elf-gcc.exe --version

   The first line ends with 14.2.1 20240816.

For the VS Code Extension, set ipro.toolchainPath to C:\IPRO\toolchain\riscv_ipro7_win32\bin\riscv64-unknown-elf-.

macOS (Apple silicon)

Needs macOS 26 or later. The SDK looks for the toolchain in /opt/toolchain/riscv_ipro7/ by default; if that folder already exists, move it away first.

1. Download and check the file:

   curl -LO https://github.com/INTELPRO-INC/ipro-toolchain/releases/download/v14.2.1-20240816/IPRO-toolchain-macos-arm64-14.2.1-20240816.tar.gz
   shasum -a 256 IPRO-toolchain-macos-arm64-14.2.1-20240816.tar.gz

   You should see f0ec4296eab0db543eb0589c7b0de8e929115afc65e13d7019c47aa7c5fdd03e. If you downloaded it with a browser instead, clear the quarantine flag before extracting, or macOS stops the programs inside: xattr -d com.apple.quarantine IPRO-toolchain-macos-arm64-14.2.1-20240816.tar.gz.

2. Extract it:

   sudo mkdir -p /opt/toolchain
   sudo tar xzf IPRO-toolchain-macos-arm64-14.2.1-20240816.tar.gz -C /opt/toolchain

3. Check it:

   /opt/toolchain/riscv_ipro7/bin/riscv64-unknown-elf-gcc --version

   The first line ends with 14.2.1 20240816.

Linux (x86-64)

The SDK looks for the toolchain in /opt/toolchain/riscv_ipro7/ by default; if that folder already exists, move it away first. The steps below use 14.2.1; for 13.1.1 use IPRO-toolchain-linux-x64-13.1.1-20230713.tar.gz from the v13.1.1-20230713 release instead.

1. Install the libraries the compiler needs (Ubuntu / Debian):

   sudo apt install libgmp10 libmpfr6 libmpc3

2. Download and check the file:

   curl -LO https://github.com/INTELPRO-INC/ipro-toolchain/releases/download/v14.2.1-20240816/IPRO-toolchain-linux-x64-14.2.1-20240816.tar.gz
   sha256sum IPRO-toolchain-linux-x64-14.2.1-20240816.tar.gz

   You should see 358484fd764a4398c16c0096a93a04d16145c31aba7d8607592ea123b54caaf9.

3. Extract it:

   sudo mkdir -p /opt/toolchain
   sudo tar xzf IPRO-toolchain-linux-x64-14.2.1-20240816.tar.gz -C /opt/toolchain

4. Check it:

   /opt/toolchain/riscv_ipro7/bin/riscv64-unknown-elf-gcc --version

   The first line ends with 14.2.1 20240816.

To keep the toolchain somewhere else, pass the prefix on every build: make -C <app> CROSS_COMPILE=<dir>/bin/riscv64-unknown-elf-.

Where the packages are published

Each version is a release of this repository with the packages and SHA256SUMS.txt. The Windows 13.1.1 package is also kept, byte for byte, in the IPRO-SDK release components-2026.09.09: the current versions of IPRO SDK Online Setup download it from there, so that release stays unchanged.

繁體中文

這個 repo 發佈 RISC-V 工具鏈，Windows、macOS、Linux 都有 14.2.1（各系統的版本見上表）。Windows 一般用 IPRO SDK Online Setup 安裝即可，它目前裝的是 13.1.1。Windows 版 14.2.1 的 IPRO7 調校模型名稱是 ipro-7-series，IPRO SDK V2.2.0 只認 intelpro-ipro7，所以搭配 V2.2.0 時會用標準 RISC-V 選項編譯、不啟用 IPRO7 DSP 擴充；要在 Windows 上用 DSP 擴充編譯 V2.2.0，請用 13.1.1。手動安裝時照上面各系統的步驟：下載、核對 SHA-256、解壓到 C:\IPRO\toolchain（Windows；資料夾已存在時先改名）或 /opt/toolchain（macOS／Linux），再執行檢查指令。macOS 若用瀏覽器下載，解壓前先執行 xattr -d com.apple.quarantine <檔名>。完整說明見文件站。
