All drivers are compiled for a specific kernel version, and that requires the kernel header files. Do not search package names and descriptions; search for files. But if you want to install ft as described above, then don’t use “make sdr14”. This is a good time to become familiar with the uname -r command: You must be root to use modinfo. You can remove the driver root again with “rmmod ft”.

Installing the ft245 USB Driver

The linus from the SDR-IQ is a byte stream with the data length and type coded in the first two bytes. By the way, if you have multiple hardwares, they have names ft, ft, ft, That means that when a newer version of Linux comes out, the most recent headers are downloaded too.

If no alias line is found, then the aliases coded into the driver files themselves are used.

If this all works, you will have your driver file ft You can load the driver by hand with “modprobe ft” you will need to be root. This is where the modinfo command comes in handy. Then from a terminal in that directory, compile the ft driver by entering “make”.

Characters from USB are appended to a 64k byte buffer, and the buffer write position is reset to zero only when the fy245 is empty. The old version will not even be found, and may not work anyway.

When you upgrade to a new kernel, you must re-compile the ft driver for that kernel. This lnux the read process to go out of sync.

Be sure to install the headers for the exact version of Linux you are running. But if you are using Linrad, see below because Linrad has its own way of installing the driver.

You can check the Linrad Makefile to see exactly what you need to remove. The above rule specifies that files named “ft? If you get a lot of error messages, don’t panic; you are probably just missing another header file. Always use your own version, and not “2. All drivers are compiled for a specific kernel linkx, and that requires the kernel header files.

That means I can’t open it unless I am root. Look at the beginning of the llnux messages for something like “can not find foobar.

There is nothing wrong with this, and it will work on many Linux flavors including older systems. But if any bytes are lost, you will read into the next block, and the two byte header will actually be data from a subsequent block.
