MCC118 gpio_set_output: gpiod_line_request_output failed

[vrusu]

I am using a MCC118 board with a raspberry pi 5 and when I run continuous_scan I get a lot of:

 

gpio_set_output: gpiod_line_request_output failed

 

Thanks

Hello @vrusu.

Was the MCC DAQ HAT example modified?

Do you have other HAT boards installed on your RPi5?

Please reply with screen captures and your code.

no other HAT boards installed. Running bookworm version of raspbian. No modifications to the DAQ, simply running "python continuous_scan.py". 

 

[Fausto]

Please install the current release (v1.5.0.0) of the MCC DAQ HAT Library and retest the example. 

If you continue to have the same issue, test the finite_scan.py and single_value_read.py examples.

Is this a new MCC 118 board being used for the first time or has the MCC 118 been used previously without an issue?

already running V1.5.0.0

 

finite_scan and single_value_read show the same problem

 

This is a brand new MCC118 board, never used before

 

Perhaps this helps, here is running with DEBUG set in lib/gpio.c, looks like only happens on pin 13.
