Looked into the python code and found the issue in the Platform.py library file within the pi_version() routine (copied it here):
def pi_version():
"""Detect the version of the Raspberry Pi. Returns either 1, 2 or
None depending on if it's a Raspberry Pi 1 (model A, B, A+, B+),
Raspberry Pi 2 (model B+), or not a Raspberry Pi.
"""
# Check /proc/cpuinfo for the Hardware field value.
# 2708 is pi 1
# 2709 is pi 2
# 2835 is pi 3 on 4.9.x kernel
# Anything else is not a pi.
with open('/proc/cpuinfo', 'r') as infile:
cpuinfo = infile.read()
# Match a line like 'Hardware : BCM2709'
match = re.search('^Hardware\s+:\s+(\w+)$', cpuinfo,
flags=re.MULTILINE | re.IGNORECASE)
if not match:
# Couldn't find the hardware, assume it isn't a pi.
return None
if match.group(1) == 'BCM2708':
# Pi 1
return 1
elif match.group(1) == 'BCM2709':
# Pi 2
return 2
elif match.group(1) == 'BCM2835':
# Pi 3 / Pi on 4.9.x kernel
return 3
else:
# Something else, not a pi.
return None
Seems that if Pi 4 CPU version would be added here (in my case BCM2711) , the problem could be easily solved. Tried to change the code but got "permission denied" when trying to save.
Would really perfer to avoid a complete re-imaging as the rest (SSH, WIFI) works perfectly well and much more convinient with the latest image version provided on the Raspberry PI homepage.
Would it be possible for me to do these proposed changes somehow directly in this Platform.py file instead? Many thanks |
