Скачать или смотреть Multi-OS Demo on Nvidia Jetson TX1 with JailHouse Hypervisor, ERIKA Enterprise 3 and Linux

This demo was done by Evidence Srl (http://www.evidence.eu.com) under a grant from the EU H2020 Project HERCULES (http://hercules2020.eu/)

In this short video we show a demo featuring:
the ERIKA Enterprise 3 for Cortex A5x (http://www.erika-enterprise.com)
JailHouse Hypervisor
Linux
on a NVidia Tegra Jetson TX1.

In the demo, the ERIKA inmate controls a DC Motor using a 3KHz PWM emulated with GPIO and timers, together with an encoder again emulated with GPIOs generating interrupts on the rising/falling edges.

A task on the ERIKA Enterprise inmate talks with the Linux inmate and viceversa using a shared memory buffer.

The Linux inmate then runs a dashboard using a Qt application, displaying the PWM control on the motor, the encoder reading, and the response time (min/avg/max) of the timer. The response time to the interrupt is in the range 5-60 us, which is in line with this kind of architecture (the Linux inmate memory requests interfere with the ERIKA memory requests). These timings will be improved during the HERCULES Project using the PREM Model implementation proposed in the project.
