Hi,I'm trying to get data from a GPS serial module link to the Soc fpga cycloneV dev Kit. But it doesn't work. I disabled the login prompt, configure the UART and use "cat /dev/ttyS0" but nothing happens. I use the Linux GSRD from rocketboard but it don't seem to included the cp210x driver for USB/uart device. It works when I send data from a PC. Anyone have solution ? Thanks.
I upgraded my Linux image with the last GSRD realease 14.1.uname -a : Linux socfpga_cyclone5 3.10.31-ltsi-02861-g801a40f# 1 SMP Sun Feb 22 16:59:00 UTC 2015 armv7l GNU/Linux My device is detected : dmesg : usb 1-1: new full-speed USB device number 3 using dwc2 usb 1-1: New USB device found, idVendor=10c4, idProduct=ea60 usb 1-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 1-1: Product: CP2104 USB to UART Bridge Controller usb 1-1: Manufacturer: Silicon Labs usb 1-1: SerialNumber: 006FA62E But it is not add as serial device And never display in /dev, I think that usbcore or usbserial driver is missing.
