Setting up Mega65 Connect for LAN

The latest Mega65 Core (0.96) now supports remote access from the  M65Connect using Jtag and now ethernet. This guide will explain how to setup a Mac/PC to use the new LAN features.


The order of these steps is not necessarily important; its just the order I think makes most sense.

Note: You must have a full login to the mega65 file host website.

  • From the file host download the latest Core package
    • Using the instructions in the download install the core to the M65
    • Copy the files in the sdcard-files directory to the root of the M65 boot SD card
    • Reboot the M65
  •  Download and install the latest version of M65Connect from the file host
    • There are some permission issues with the MAC version of the  application, follow the instructions in the download section to resolve these
  • Connect the Mac/PC and the M65 to the network
  • The Mega65 uses IPV6 for communication with M65Connect, for Windows users go into the network configuration and ensure IPV6 is ticked, its been a while since I used windows and I'm not sure if IPV6 is enabled by default. A Link-Local address will automatically be assigned be assigned. For Mac users this should already be enabled.  Linux users may need to google, sorry.
  • Start M65Connect on the Mac/PC
    • In the bottom left of the window the status should read Not Connected to MEGA65
  • On the Mega65 press SHIFT £
    • The power light on the Mega65 will flash Green/Yellow
    • In the Bottom left of the M65Connect window the message should now read Connected to MEGA65 via LAN 
You should now be able to control the M65 from the Mac/PC, click the SD Card button in the M65Connect and you should be able to copy files too and from the MEGA65.

Trouble shooting:

  1. When you try to issue any commands to the M65 via M65Connect the M65 screens fills with random characters and crashes
    1. Likely cause is the ETHLOAD.M65 file has not been copied to the ROOT of the M65 boot drive
  2. M65Connect does not connect even though the M65 light is flashing
    1. Check and replace all ethernet cables, yes even if they are brand new
    2. The M65 has a 10/100 network interface, if you are using a switch ensure the port the M65 is connected to is not hard coded to gigabit or that the switch supports multiple port speeds
    3. If you are using a direct cable from the M65 to the Mac/PC you may need a cross over ethernet cable not a straight thought (normal) cable. 
    4. If the Mac/PC is using USB to Ethernet it may not support 10/100 speeds this is fine if its plugged into a switch but a direct connection to the M65 will not work
    5. If you are using a managed switch ensure that the Mac/PC and the M65 are in the same VLAN, even if your network is configured to use IPv6 routing it will not work because the M65 only supports link-local addressing 
I hope this helps.
