What is the MAC address of the Compute Module?
The MAC address is assigned by the Compute Module itself and is derived from the CPU serial number.
The first 3 octets (B8:27:EB) are fixed and assigned to Raspberry Pi Foundation. The remaining 3 octets
are the last 6 hex digits of the CPU serial number. For example, if the CPU serial number is
0000000096bf4e08 the MAC address will be B8:27:EB:BF:4E:08. The CPU serial number can be
obtained by using:
cat /proc/cpuinfo
How long does it take to flash the Compute Module?
It depends on the size of the image being flashed. USB read and write speeds are typically 5MB/s. So a
4GB image will take approximately 13 minutes to write. That time will double if verification is used. Using
the Etcher flashing software can speed up the process significantly.
How can I find out the LAN IP or MAC address of the host display from the Compute Module?
The Python SDK includes the functions command_ip_address_read() and
command_lan_mac_address_read() that will return the IP and MAC address of the display.
How can the Compute Module be automatically shut down when the display is turned off?
A new Expert mode control has been added to the OSD that will enable performing a shutdown of the
Compute Module when the display is turned off via a command, power button, OSD menu, or IR remote
control. See CM Auto Shutdown in section 8.18
