Status-LEDs

[alenken]

Hello,

I am new to Raspberry Pi and I’ve recently encountered some issues while trying to connect the RevPi Connect+ with the DIO module.

I have configured all modules using PiCtory, following the PiCtory Checklist and the Video Tutorials on YouTube. However, I’ve noticed that the power LEDs on both the DIO and RevPi Connect+ modules are still red, even though the other signal LEDs are green.

I have also checked the status and connection of the modules using a command via SSH and the results are like this:

Code: Select all

pi@RevPi-SPKT:~ $ piTest -r RevPiStatus,b
1 Byte-Value of RevPiStatus: 00000001

pi@RevPi-SPKT:~ $ piTest -r Status,b
2 Byte-Value of Status: 00000000 00000000

pi@RevPi-SPKT:~ $ piTest -r Output_Status,b
2 Byte-Value of Output_Status: 00000000 00000000

And

Code: Select all

pi@RevPi-SPKT:~ $ piTest -d
Found 2 devices:

Address: 0 module type: 105 (0x69) RevPi Connect V1.0
Module is present
     input offset: 113 length: 6
    output offset: 119 length: 5

Address: 31 module type: 96 (0x60) RevPi DIO V1.4
Module is present
     input offset: 0 length: 70
    output offset: 70 length: 18

I’ve seen some topics about the problem, but I still can’t fix it.
I’m currently stuck and any help would be greatly appreciated. Thank you in advance!

Best Regards, alenken

alenken, Firstly, thank you very much for the information you have collected. This is really helpful and gives me a good overview.
The value 1 in the variable RevPiSatatus means that at least one IO module is connected which has not been configured with PiCtory. See here:
https://revolutionpi.com/tutorials/soft ... rect=en-US

This contrasts with the output of "piTest -d". I would have expected an error to occur here. So it is questionable what is really not working in the system.

Anyway, I recommend updating your system using the following checklist and restoring it to factory settings.

If you are interested in tracing this error, I recommend that you make a backup beforehand.

Hello!

Please correct me if I'm wrong but this is bit 0 that is blinking, which means "picontrol running", so everything seems in order.

When I had the exact same issue it was because I messed up the X4 connections as described here:
https://revolutionpi.com/tutorials/uebe ... en-connect
and here:
https://revolutionpi.com/tutorials/over ... wer-supply

I don't remember what went wrong back then.

Thank you very much! The RevPi Connect+ is running properly now! The versions of the extension modules have been updated to newer versions than before, which are V1.4 of DIO and V1.3 of AIO.

I’m not sure if I set up some environment variables that conflict with the system, or if the old versions just can’t perform correctly. Previously, I only installed librealsense2 from the IntelRealsense source and set up some Python virtual environments. Could you explain to me what might have happened here?

Based on this experiment, I think I should try installing all the equipment with RevPi before installing anything else on it

Code: Select all

pi@RevPi44885:~ $ piTest -d
