This is a show case where we have our running MV32 on Raspberry Pi 4 ( Desktop, Raspberry Pi OS 64-bit).

System prerequisites:

HW: 

1) MV32 CS sample on the new 5G starter kit

2) Raspberry Pi 4 with Raspberry Pi OS (64-Bit), make sure that Raspberry Pi 4 device is new (2021 and further)

3) connect the MV32 sample to Raspberry Pi 4 on the USB 3.x interface

Linux OS:

On Raspberry Pi OS, make sure that the Raspberry Pi OS Linux kernel version is the latest ( v5.15.x), update with following steps:

=============================

sudo apt update
sudo apt full-upgrade
sudo rpi-eeprom-update
