During the last 2 years as a product, design house and EMS, LACROIX had to answer several component shortages issues especially on processor. Processors are not so easy to multi-source as they are running SW, especially low-level SW which is linked to the chipset. The team has spent a lot of time to port low level SW to new CPU target due to this issue. The solution presented during this session is a SW platform solution targeting MCU and CPU which permits to switch from a CPU to another with a limited effort using Zephyr SW platforms and Containers.
