WARNING: Hardware auto-detect failed, running in raspi-3 mock mode #105

Closed alexbjorlig closed 4 years ago

alexbjorlig commented 4 years ago

I am trying to run node-rpio on the raspberry pi 4, with the 64-bit balenaOS.

I am running the docker image balenalib/raspberrypi4-64-node:12, and everything builds ok. But when I start the Node process using rpio, I get this warning: 

WARNING: Hardware auto-detect failed, running in raspi-3 mock mode

Do you have any ideas of how to fix this?

jperkin commented 4 years ago

The code which tries to detect the hardware is here, specifically it looks at the output of /proc/cpuinfo and attempts to parse the line starting "Revision".

In your case it isn't finding a match. Could you paste what that line contains on your OS?

alexbjorlig commented 4 years ago

Ahh ok - would love to get involved, so thanks for pointing out the file detecting the hardware. Here is the output:

Ok, so your OS differs from all the others that this module has been tested on so far, and doesn't include the board revision. Could you find out where it stores this information instead?

jperkin commented 4 years ago

Actually according to this it's stored in different files - could you output their contents?

alexbjorlig commented 4 years ago

The Balena OS and developer experience is really outstanding, makes it so easy to deploy and maintain code on raspberry pi's. So would be awesome if we could make it work with node-rpio. Btw, thanks for an awesome repo 🚀 Here is the output of the files:

/sys/firmware/devicetree/base/serial-number

100000001cbcbcaf

/proc/device-tree/serial-number

100000001cbcbcaf

Hmm, are there any other files in those directories that might be more useful? The serial number is going to differ between devices (I would imagine) and the model isn't great for parsing.

alexbjorlig commented 4 years ago

I am not that much into Linux - but maybe this comment could help?

jperkin commented 4 years ago

I just pushed v1.2.3 which should fix this, can you try that?

alexbjorlig commented 4 years ago

@jperkin - you are fast 🤯

v1.2.3 seems to fix the issue - I am not seeing WARNING: Hardware auto-detect failed, running in raspi-3 mock mode! Looking forward to starting the actual project later today, where I will try to implement the poll/callback example for adding buttons.

alexbjorlig commented 4 years ago

Tested with a button - and it worked on Raspberry pi 4. Thanks for the help!
