Linux Kernel Driver for Raggedstone1

Building/Using under Linux 2.4.x

Make sure you have /lib/modules/`uname -r`/build/include, otherwise create a symlink:

cd /lib/modules/`uname -r`/
ln -s /usr/src/linux build

and then


should suffice to build the module. We've tested it under 2.4.4 as well as 2.4.27 This should also have compiled the user-space test-program called “send_to_fpga”.

Creating the device node /dev/fpga

 make makedev


 mknod /dev/fpga c 100 0

(This major number might vary, check the kernel log after insmod for details)

Loading the Module

insmod ./mod_rs1_pci_driver.o


./send_to_fpga 0x1234

If all went well, this should make the FPGA board display 1234 on the 7segment display.

Building/Using under Linux 2.6.x

Compiling the Kernel Module

make -f Makefile.26

Compiling the Userspace Application

make send_to_fpga

Loading the Module

insmod ./mod_rs1_pci_driver.ko
