dpserver: Dpserver is the user-space daemon that converts ASCII strings on a TCP connection into the low level packets that read and write registers in the FPGA. You can get, install, and test dpserver with the following commands:
wget http://demandperipherals.com/downloads/dpserver-latest.tgz tar —xzf dpdrivers-latest.tgz cd dpserver make sudo make install # connect Baseboard to your PC sudo chmod 666 /dev/ttyUSB0 stty -F /dev/ttyUSB0 raw # no CR-to-CRLF translation cat DPCore.bin > /dev/ttyUSB0 # green LED turns on # start dpserver and test Baseboard LEDs dpserver /dev/ttyUSB0 /usr/local/bin/dpset bb4io leds 55
