Want to isolate LPC55S36 on EVSE-SIG-BRD2X board and work on Lumissil CG5317

Hi team,

I am working on EVSE-SIG-BRD2X board, where I want to isolate LPC55S36 chip on the board and work only on Lumissil CG5317.

I have two EVSE-SIG-BRD2X boards, one I use it as EVSE and the other one as EV

I actually want to test EV - EVSE high level communication between the two boards via Ethernet - PLC bridge

So, I have my ISO 15118-2 software stack for both EVSE and EV

I will run my EVSE software on one side on a Linux platform and EV software the other side on a Linux software

This will establish a client(EV) - server(EVSE) High level communication

My circuit is like the below one:

PC <---> Ethernet <---> EVSE-SIG-BRD2X( EVSE ) <----> CP,PP <---> EVSE-SIG-BRD2X( EV )<--->Ethernet <---> PC

The CP and PP pins facilitate communication between EV and EVSE via power line communication (PLC)

I have gone through the below documents to understand and implement

1. UG10140 - EVSE-SIG-BRD2X Board User Guide

2. UM12128 - EVSE-SIG-BRD2X User Manual

3. X-EVSE-SIG-BRD2X

Please let me know if any further information is required.

Looking forward for your kind response and support

Thanks in advance

Re: EVSE-SIG-BRD2X board bring-up

Hi team,

I am working on EasyEVSE EV Charging Signal Board (EVSE-SIG-BRD) with imx93 FRDM dev board

I have followed GitHub - nxp-imx-support/meta-imx-frdm: Yocto layer for i.MX FRDM boards

to build the yocto image for imx93 frdm

I added meta-nxp-easyevse-mpu (GitHub - nxp-imx-support/meta-nxp-easyevse-mpu: Easy EVSE MPU Yocto Layers)in the directory imx93_yocto_bsp/sources/ and also added in bblayers.conf

now I am facing issue of patch error (below):

Re: EVSE-SIG-BRD2X board bring-up

Hello,

The EVSE Kit for MPU is using i.MX93. You can refer the documents in EVSE page.

https://www.nxp.com/design/design-center/development-boards-and-designs/EV-CHRG-STN-MPU

If you want to verify it on i.MX8MM, i think you need modify lots of source code to make it work on i.MX8MM based on the Getting Started with the EasyEVSE Development Platform here.

EVSE-SIG-BRD2X board bring-up

Hi

Hope you are doing well!

I want to use MII host interface of CG5317 for connection with host MPU (nxp i.MX 8M Mini)

my question is

1. How can I achieve this communication using MII host interface?

2. Does the CG5317 chip on EVSE-SIG-BRD2X has firmware already flashed in it?

3. I connected RJ45 port to my host MPU (nxp i.MX 8M Mini) with ethernet but not able to detect the mac address or ip address from my host terminal

I have attached screenshots and images of my circuit for your kind reference

somesh

Re: Want to isolate LPC55S36 on EVSE-SIG-BRD2X board and work on Lumissil CG5317

Hello,

If you only want to test Lumissil CG5317, please use Lumissil CG5317 official board. If you want to only test CG5317 on EVSE-SIG-BRD2X board, you need to do hardware rework and we can't make sure that you can control CG5317 after rework.
