I am currently trying to make a PCI-device-UIO-driver work on JetPack 3.2.1 with L4T 28.2.1.
So far i have activated UIO support within a customized kernel, added a UIO-device to the device-tree and added
earlyprintk uio_pdrv_genirq.of_id=generic-uio to the bootargs.
This is my device-tree-node:
compatible = “uio-generic”;
reg = <0x0 0x10007000 0x0 0x1000>;
interrupts = <0x0 0x1>;
After this configuration no UIO-devices show up in /dev/ .
When i try to modprobe uio, no errors are shown but there are no additional modules started. When i try to modprobe other UIO-drivers like uio_pci_generic they also show no errors but do not start.
I have also searched for entries in /sys/class/uio but the folder is empty.
So my question is, can I even make the UIO-driver work on JetPack 3.2.1 or do I need to find another solution?
Thanks in advance
