Good evening, i’m trying to use the fan_pwm as a custom pwm, as i do not have any fan to use with my board.
I’m using a custom carrier board with an Nvidia AGX Orin, and i want to use the 32a0000.pwm, but when i try to access it using " echo 0 > export" i get an error saying that the resource is already busy.
Is there any way to free it? thanks in advance
Sorry for the late response.
Is this still an issue to support? Any result can be shared?
Good morning,
i still need support, yes.
I tried to unlink writing to unexport with “echo 0 >unexport”, but i get an error saying that there is no such device.
When i tried the same technique with other pwms, it worked just fine, but for some reason with this one it doesn’t work.
I saw there is a Supplier-Consumer link between the 32a0000.pwm and the fan_pwm, and in each respective folder a “Consumer” and “Supplier” folder can be found, i suppose it links the two services?
I haven’t found a way to unlink them yet, maybe there’s some driver that allocates that resources and doesn’t let it go?
