 ## Radioberry Device Driver
 
+
+This device driver is special made for the RPI-4.
+
+
+Hereby a step by step setup.
+
+
+Step -1-
+
+CL025 FPGA Radioberry users:
+Copy the gateware radioberry.rbf into the folder /lib/firmware
+
+CL016 FPGA Radioberry users:
+Rename your radioberry-10CL016.rbf gateware to radioberry.rbf 
+Copy the gateware radioberry.rbf into the folder /lib/firmware
+
+Loading the device driver will also load the gateware (content of the rbf file) into the FPGA 
+
+
+
+Step -2-
+
+Make a module folder in the driver area of your running kernel, and install the driver called radioberry.ko in this folder.
+
+cd /lib/modules/$(uname -r)/kernel/drivers
+sudo mkdir sdr
+
+copy the radioberry.ko to /lib/modules/$(uname -r)/kernel/drivers/sdr
+
+
+
+Step -3-
+
+run the command:  sudo depmod 
+
+Check:  use the command: modinfo radioberry 
+Gives you detailed info about the radioberry device driver.
+
+
+
+Step -4-
+
+load the device driver 
+
+run the command: sudo modprobe radioberry
+
+In the folder /dev the radioberry must be present using the ls command.
+Also possible to check by the command: lsmod |grep radioberry
+
+
+Step -5-
+
+Optional step.
+
+If you like to load the device driver during boot, execute the following:
+
+/etc/modules-load.d/modules.conf
+
+add the device driver in this file, see content example:
+
+# /etc/modules: kernel modules to load at boot time.
+#
+# This file contains the names of kernel modules that should be loaded
+# at boot time, one per line. Lines beginning with "#" are ignored.
+
+i2c-dev
+snd-mixer-oss
+snd-pcm-oss
+radioberry
+
+
+
+Step -6-
+
+Optional step.
+
+sudo chmod 666 /dev/radioberry
+
+Makes it possible to run the radioberry firmware version for the device driver, running as the logged in user:
+
+
+
+
+Step -7-
+
+Run using the command ./radioberry firmware or sudo ./radioberry
+
+
+
+Step -8-
+Start a SDR program!
+
+
+Have fun listening to your Radioberry using the radioberry device driver.
