How can I power on my module?

What will I find in my module?

Off-the-shelf products are shipped with a standard in-house-developed software.
The definition of standard, in this case, is “the environment which SECO adopts for validation”.
Anyway, custom in-house-developed software with different defaults can be built.
Contact your reference sales for further information.

Edgehog OS

Starting from Linux Kernel version 5.10, the Board Support Package (BSP) for this board is fully integrated within Edgehog OS, the operating system for the All-In-One IIot platform CLEA developed by SECO and based on Yocto. Edgehog OS is intended to provide the highest standards in terms of security and stability thanks to features like OTA (Over the Air) updates, double partitions, and fallback procedures. Edgehog OS integrates a Device Manager to communicate with the Cloud and allows a family of products to be managed as a fleet.

Source code

The source code for Edgehog OS can be found at the following Gitlab organization. To build a complete BSP image from source, you can follow the readme of the repo manifest.

Binaries

The binaries (U-Boot, Linux Kernel, Yocto image) associated with the various Edgehog OS releases can be found at the following Release page.

 

Legacy Software

This section contains releases (source code and binaries) for older BSPs and Yocto images.

Source code

Source code for linux kernel, u-boot and yocto seco layers is available here.
