Debug mode
The PMD has a method to interact with a live, running system. This is referred to as "Debug Mode".
As usual, commands listed here are for linux, generally Ubuntu/Debian. Again, there is probably a method for doing this in Windows, but we won't go into that here.
How to activate Debug Mode:
Plug in the PMD via USB and wait for it to be recognised. In the root directory of the PMD run
Reboot the PMD. When it reboots, it will look for this file. If it exists, the PMD will enable a network interface over USB and disable the mass storage system over USB. Linux kernel >2.6 contains the ethernet over USB drivers by default, so it should automatically appear as a network interface.
The PMD is configuired to have the IP address 192.168.17.17
Configure the new USB ethernet device (assume it is eth1) with
If it is not eth1, use dmesg to determine which ethernet interface is created. Access with:
The password is "root" (as can be seen below)
To disable debug mode and return to normal use, simply delete the file "activatedebugmode" and reboot.
