6.1. OpenBMC-based Linux embedded software[edit | edit source]
The OpenBMC-based Linux® embedded software is part of the STM32 MPU embedded software offer.
It is a set of software (see architecture overview) created to ease the integration of our STM32 MPU devices inside the OpenBMC[3] project.
It is made up of:
- an open-source Linux® distribution, based on the OpenBMC community project, running on the Arm® Cortex®-A processor(s).
- firmwares, running on the Arm® Cortex®-M processor: FwST-M Packages
OpenBMC[3] is a Linux operating system targeting embedded devices.OpenBMC includes a collection of applications and services that address BMC functional requirements. It is most commonly deployed on a companion chip paired with a server processor, where it provides a management interface between the administrator and the server. The BMC is also responsible for managing the chassis, firmware updates, sensor management, and access control.
The Linux® distribution relies on the OpenSTLinux board support package (U-Boot, TF-A, OP-TEE, Linux kernel) complemented with a user-space with a features set brought by OpenBMC.
The OpenBMC forked repository[4] is delivered on the official STMicroelectronics GitHub[5].
6.1.1. OpenBMC-based Linux Distribution for Arm® Cortex®-A[edit | edit source]
Updated OpenBMC v2.18.0 is the version delivered with the OpenBMC-based Linux-ecosystem OSTL-6.2.0_OBMC-2.18.
The release note and readme files give information and details about the features / content / restrictions of the OpenBMC-based Linux Distribution.
| Firmware | Release note | Version |
| OpenBMC Linux Distribution | Readme file and ST readme.md | OSTL-6.2.0_OBMC-2.18 |
6.1.2. FwST-M packages for Arm® Cortex®-M[edit | edit source]
The release notes give information and details about the features / content / restrictions of the Packages.
Since OpenBMC-based Linux ecosystem-v6.1.0, the TF-M is no more supported.
They do not explain how to download the software. For that, refer to How to download the software and start with this release chapter.
| Firmware | Release note | Version |
| STM32CubeMP2 Package | STM32CubeMP2 Package release note - v1.3.0 | STM32CubeMP2 Package v1.3.0 |
7. Development tools[edit | edit source]
The tools version has to match the version of the ST BSP components, aka Yocto-based OpenSTLinux BSP v6.2.0, available in Yocto-based OpenSTLinux ecosystem release note - v6.2.0#Development tools.
8. Documentation[edit | edit source]
