Infineon ModusToolbox vs RISC-V GNU Toolchain

Infineon ModusToolbox is a free development ecosystem for building embedded applications with Infineon microcontrollers. Its desktop applications support software component management, peripheral and middleware configuration, compilation, programming, and debugging. Supported device families listed include PSOC, TRAVEO T2G, XMC, AIROC Wi-Fi and Bluetooth, and USB-C Power Delivery microcontrollers. The installation package supports Windows, Linux, and macOS. A GNU make build system supports workflows through desktop IDEs, a command-line terminal, or continuous integration, with named IDE options including Eclipse, Visual Studio Code, IAR Embedded Workbench, and Arm MDK with µVision. Embedded assets include board support packages, drivers, middleware, and code examples, with runtime software provided through GitHub-hosted repositories. Board targets can be customized or retargeted. ModusToolbox for Security lists Trusted Firmware-M, cryptographic libraries, secure boot, firmware updates, and secure communication protocols. Infineon also lists training videos, documentation, code examples, and libraries as development resources.

RISC-V GNU Toolchain is a C and C++ cross-compiler for building bare-metal ELF or Linux ELF toolchains. It supports RV32 and RV64 targets, with RV64GC as the default, and lets builders select architecture extensions and ABIs. Bare-metal configurations can use Newlib or Picolibc; Linux configurations can use glibc, musl, or uClibc. Multilib builds can target 32-bit and 64-bit systems for Newlib and Linux/glibc toolchains. The toolchain includes GCC, binutils, GDB, and supported libraries. LLVM can be built alongside it using a configure option, though that option cannot be combined with multilib settings. The project documents testing with DejaGNU and make check targets, plus QEMU, GDB, and experimental Spike simulator options whose availability varies by toolchain. Hosts include Linux and macOS; Windows use is through a Linux subsystem or Cygwin. A build needs about 8 GiB of disk space, and cloning takes around 6.65 GB. It is free and open-source, with development material aimed at developers and advanced users.
