Asymmetric Multi Processing with Linux & Zephyr on the STM32MP1
In the embedded world, more and more vendors offer Arm-based System-on-Chips (SoC) including both powerful Cortex-A CPU cores, designed to run a full-featured OS such as Linux, and one or more low-power Cortex-M cores, usually found in microcontrollers, designed to execute bare-metal or RTOS-based applications.
[...]
While the Linux kernel can run on a wide range of devices, it requires a decent amount of memory (> 4MB), and therefore cannot be used on memory-constrained microcontrollers.
Enters Zephyr, a project initiated by Wind River, now developed as a Linux Foundation project.
| Geniatech XPI-3288 Raspberry Pi lookalike features Rockchip RK3288 SoC
Geniatech XPI is a family of single board computers following Raspberry Pi 3 form factor. We first covered XPI-S905X SBC in 2018, which was followed by XPI 3128 board last year.
The company has now launched another model with Geniatech XPI-3288 SBC powered by Rockchip RK3288 32-bit quad-core Cortex-A17 processor coupled with 2G RAM and 16GB eMMC flash.
