macOS caches public keys keys in .ssh/known_hosts and normally warns if there is a conflict.
If this is your problem (and you haven't adequately explained what you did or what error you see) it can be fixed by deleting the offending key (or the whole file). There are many ssh settings on the Mac which determine how ssh connects.
Not sure which Pi model you are talking about.
If you have a model with the 40-pin expansion header you can assume that anything which works on any model of Pi will work on your model. There is one exception and that is software targeted for the compute module extra GPIO.
Is it generally safe to assume that anything (software-related) that works with a Pi Zero will ALSO work with a 1.2 B+,
Yes. They have exactly the same core components including the SoC/CPU; the one on the Zero is just binned with a higher clock speed.
Are there things that even the Zero can do that the old 1.2 B+ can't?
Nothing beyond the obvious (...
WaveShare WM8960 Audio HAT driver installed OK ("sudo dkms status" responses OK), but device not listed ("aplay -l" shows nothing). How to fix it?
The spec says the HAT is compatible to RpiZ/ZW/2/3B/3B+, but does NOT
mention Rpi4B or buster.
This means buster might NOT be supported.
So the installed driver should work ...
I have same problem with an 16GB SD card of Samsung. After trying all the software solutions available on internet i moved onto hardware issues and figured out there is very small crack on the SD card that can not be observed easily. i observed it with flashlight.
Its cause was the SD slot of raspberry pi. I put the PI in my backpack where he received some ...
There is a tool called katoolin. You can use that software. The script is written in python. Just opne the software from terminal with
sudo python katoolin.py
and you will find options for everything
From the information you have given so far it seems that the RasPi has a working WiFi interface wlp2s0. As shown by ip addr it has a dynamic ip address 192.168.1.160/24 that is usually given by a DHCP server on the network. So it must be connected to a remote access point and everything is good. The command iw wlp2s0 link would give us more details about the ...
I ran into a similar issue trying to cross-compile code for the Raspberry PI Zero (armv6) using a newer GCC 8.
Current toolchains are often not built with the --with-arch=armv6 flag. This results in binaries which are not compatible with armv6 and therefore you may get Illegal Instruction error.
I created a github repo where you can download a toolchain ...
Using the compiler toolchain from https://sourceforge.net/projects/raspberry-pi-cross-compilers/
For pizero the cross-compiler is available from the link cross-gcc-9.1.0-pi_0-1.tar.gz
This compiler version is :
Using built-in specs.
Power to RpiZero = 12V Battery > 12V to 5V volgage regulator
Push button with one end connected to Rpi GPIO.
Is it OK to connect the other end of the button to the 12V battery ground?
Yes, no problem.
Let us first look at Oreilly tutorial's push button circuit.
This question is unanswerable without more information. Most switch mode regulators have a common -ve between input and output, but not all.
However, even if the connection is common, it is bad practice. Connections to GPIO pins
should have the shortest most direct connection with no ground loops.
In addition motor vehicles are a hostile environment for ...
