chraac / fake_vcgencmd

vcgencmd partial clone for non-Raspberry Pi devices to allow Android RasPi Check (rpicheck) to run. Generic Linux, Armbian, ODroid XU4, rock64 SBC to allow Raspberry Pi tools/scripts

Fake vcgencmd for generic Linux, Armbian, Odroid, Pine64, Rock64 and other SBCs

Shell script vcgencmd partial clone to allow Raspberry Pi tools/scripts to run unmodified on SBCs. Works with Armbian (and probably works with x86 too).

Works with Android app https://github.com/eidottermihi/rpicheck

Some Armbian builds already include this script. However, the script can be used as-is on many systems. In case Armbian does not include this script in their build for your board, but you have tested that this script works properly, you can request Armbian to include it for your board.

Install vcgencmd into /usr/bin/vcgencmd and set execute bit. Example from source checkout:

sudo cp vcgencmd /usr/bin/vcgencmd
sudo chmod a+x /usr/bin/vcgencmd

Originally relied on rock64_health.sh - https://github.com/pfeerick/rock64-scripts now uses /sys/ interface.

Install over the web:

wget -O /usr/bin/vcgencmd https://raw.githubusercontent.com/clach04/rock64_vcgencmd/master/vcgencmd
chmod a+x /usr/bin/vcgencmd

What works

vcgencmd version
vcgencmd measure_temp
vcgencmd measure_clock arm

vcgencmd measure_volts core  # this is faked out and incorrect, just enough to satisfy rpicheck
vcgencmd measure_clock core  # this is faked out and incorrect, just enough to satisfy rpicheck

Adding support for new parameters

Add the following to the end of the script vcgencmd for quick and easy debug logs:

exit
# remove/comment out exit about for debug logging
# NOTE may need allow permissions on file:
#	sudo chmod a+w /var/log/vcgencmd.log


# if we got here, unrecognized parameter
# log it for debugging purposes

# on this device /var/log is ramfs folder2ram
LOG=/var/log/vcgencmd.log
LOG=/tmp/vcgencmd.log


date >> ${LOG}
echo PARAM star ${*} PARAM >> ${LOG}
echo PARAM one ${1} PARAM >> ${LOG}
echo PARAM two ${2} PARAM >> ${LOG}
