I’m using the uio_pruss driver. And I’m trying to configure the /dev/uio[0-7] files early in the boot sequence. I need to setup a certain group for some of them.
But my setting gets overwriten later in the boot sequence. I found the file /etc/udev/rules.d/uio.rules causing one override. But even deleting that file doesn’t help, my initial setting gets overriden. And I cannot find the process causing that problem.
Does anybody know which process[es] override the group setting of /dev/uio[0-7]?
