The Power PMAC CPU’s USB port now acts as a flash memory stick providing internal directory
structure and file access from a Windows PC while the board is unpowered.
Figure 1. USB Connector is for serial port diagnostics.
Figure 2. USB Connector is for a mass storage device
When configuring the USB connection for mass storage three folders will be present, “etc”,
“ppmac” and “etherlab”. The “ppmac” folder represents the Power UMAC Firmware binary
applications and should not be modified. The “etherlab” folder contains the EtherCAT
configuration and should not be modified. The “etc” folder contains the network settings. The
file interfaces maybe inspected to determine the current configured network setting of the Power
PMAC. WARNING editing the interfaces file with notepad will prevent the network setting from
working.
