Dear all, I wanted to create a simple character device on L4Linux. I managed to cross-compile the module and run it on L4Linux on Versatile Express Realview Cortex-A15 ARM machine using the following command: make -C ~/l4re/obj/l4linux/arm-mp/ M=$PWD CROSS_COMPILE=/usr/bin/arm-linux-gnueabi- L4ARCH=arm CONFIG_TCG_TPM=m modules V=1 When I try to insert the module using the insmod command I get the following printed out from the module: chardev: registered correctly with major number 254 chardev: device class registered correctly chardev: device class created correctly With no failures in initializing the device printed at all. Also lsmod displays the device in the module list with status live. However, the device doesn't appear in the /dev/ directory and hence I can not access it using the file operations. Any ideas where is the device located or how can it be accessed on L4Linux? _______________________________________________ l4-hackers mailing list [email protected] http://os.inf.tu-dresden.de/mailman/listinfo/l4-hackers
