1 - Introduction

This repo holds the tools necassary to enable SPI communication between PHYTEC's supported dev kits and the Lumissil IS31CG5317/IS32CG5327 device.

There are some key items included in this meta-layer.

• Lumissil lms-eth2spi SPI Driver - spi driver that will be built into the BSP.

• Host Load Services - firmware loading services that are used on bootup when the lms is in host-load moad.

2 - Testing all Components

1. Check to see if PLC device connected successfully.

dmesg | grep spi

AM62 Example Output

root@phyboard-lyra-am62xx-2:~# dmesg | grep spi

2. At this point the hardware is setup and the PLC device is connected and waiting for application software to write/read from the device. Refer to and contact Lumissil for specific device documentation: https://www.lumissil.com/applications/communication/electric-vehicles-charging/vehicle-charging/is32cg5317

3 - Host Software

1. The host software example binaries were cross-compiled and included in this layer.

Communicating with the Device

Device information can be found by running the management tool and passing it the correct mac address of the hardware. Our kit gets a response using the following:

root@phyboard-lyra-am62xx-2:~# ./examples/management_tool/management_tool -d 00:16:E8:00:00:01 -a`cat /sys/class/net/seth0/address` -c "device_info 3"

Good Connection

root@phyboard-lyra-am62xx-2:~# ./examples/management_tool/management_tool -d 00:16:E8:00:00:01 -a`cat /sys/class/net/seth0/address` -c "device_info 3"
