Third-party tools and design resources supporting the LEON and NOEL processors

Linux for RISC-V NOEL

RTEMS5 for RISC-V NOEL

The software provided are mainly RISC-V NOEL BSPs, device drivers and compiler toolchains together with the integration into the developer tools/ecosystem

BCC1 - LEON bare-metal cross-compiler system

Bare-C Cross-Compiler System for LEON3/4 GCC 3.4.4 and GCC 4.4.2

RTEMS Cross-compiler System (RCC)

RCC provides a real-time operating system environment with comprehensive support for device drivers, making it suitable for time-critical applications requiring reliable performance and extensive hardware support.

RTEMS-5 File System backend

Software package implementing the backend to the file system layers of RTEMS-5 for certain NOR FLASH memory components.

TM/TC Software Stack API

Implements a Software Stack for receiving and transmitting TM/TC using the CCSDS/ECSS hardware IPs for RTEMS, VxWorks and Linux in LEON environment.

MKPROM2

MKPROM2 is a utility program that converts a LEON RAM application image into a bootable ROM image. The resulting bootable ROM image contains the system initialization code, an application loader, and the RAM application itself. The RAM application is compressed with a modified LZSS algorithm, typically achieving a compression factor of 2.

GR712RC Boot Software

GR712RC Boot SW is a flight system software suite targeting GR712RC systems. The purpose of GR712RC Boot SW is to provide initialization, maintenance, and application loading functionality to a payload or on-board computers.

GRBOOT-STANDBY

GRBOOT-STANDBY is a SpaceWire/PUS standby extension for the GRBOOT flight boot loader. The software is compatible with the standby function as described in SAVOIR-GS-002.

GRBOOT

GRBOOT is a flight system software suite targeting GR740, GR712RC and UT700 systems. The purpose of GRBOOT is to provide initialization, self-test and application loading functionality to payload and onboard computers.

Zephyr

Zephyr RTOS provides a lightweight, efficient real-time operating system environment with a small footprint, making it ideal for embedded systems requiring minimal resource usage.

Gaisler Buildroot

Gaisler Buildroot distribution, aimed for both LEON and NOEL, based on LTS versions of the open-source Buildroot tool, is our officially supported Linux development and build environment.

Linux for LEON

Linux kernel. All host tools and Linux software are provided in full source.

VxWorks 6.9

VxWorks 6.9 provides a stable, mature platform with extensive driver support, ideal for legacy systems.

VxWorks 7

VxWorks 7 delivers advanced features and a flexible development environment for the LEON processors, ensuring robust performance and compatibility with various development hosts. We also provide VxWorks 7 SR0650 board support packages for NOEL processors.

NOEL Bare-Metal Cross-compiler System (NCC)

NCC is a bare-metal toolchain for NOEL-V. It can be used for developing single-threaded C and C++ applications.
