I'm trying to test the "piTest" program and found a problem with the "piTest -S" (pic 1) command. As the documentation said (pic 2), when stopping the I/O update with the command "piTest -S", the function "piControlStopIO" will be called and all data at inputs of I/O devices should not be written to the process image of the RevPi master (Core, Connect). But in my case (see pic 3) when I stopped the I/O update with the "piTest -S" command and changed the inputs of my DIO module, all the changes were written to the process image. It's a bug? Or maybe I'm misunderstood what the command "piTest -S" can do?
Thanks for any help!
P/S: when "update of I/Os and process image is stopped" is on, the PWR LED blinks red on the Connect module.
