About SpiderSoM

The SpiderSoM is a programmable, non-volatile solution based on Intel® MAX®10 FPGA, which enables it to deliver full-featured FPGA capabilities: support for various soft-core CPUs, video-processing algorithms, etc. The SpiderSoM promotes the free and open design concept: all resources, like i.e. design files, gerber, source code, etc. are available under certain open licenses. The SpiderSoM is available as a low cost and extremely flexible platform which enables user to setup a running system according to the required specification in a very short time.

This module can be considered as a cost-optimized alternative to the MX10 module.

Software

MX10 and SpiderSoM modules provide a USB device interface implemented with a Microchip PIC16F1454 microcontroller (MCU).
On the host side Linux is supported as Operating System, currently Ubuntu 16.04 LTS is marked as a reference base.
On the SoM side the MCU is connected to three interfaces:

  • UART - Accessible as standard serial device ( /dev/ttyACMx ).
Connected to the FPGA.
  • I2C - Accessible as standard i2c device ( /dev/i2c-x ). Requires driver.
Connected to module PMIC, charge controller, RTC and FPGA.

Currently Windows is not fully supported. One can use the serial interface by manually installing the USB Serial driver.

  • Open device manager and select "Other devices" > "Unknown Device". Open its properties and verify that under the details tab the property "Device install path" reads "USB\VID_04D8&PID_EFD0&MI_02\..." Then in the general tab, select "Update driver". Here select "Browse my computer..." and "Let me pick from a list...". Select "Ports (COM & LPT)" then select manufacturer "Microsoft" and model "USB Serial Device". A new COMx device will then be created which can be used with serial tools.
  • Alternative way is to use Zadig (https://zadig.akeo.ie/). With this tool you can overwrite the Composite-Device-driver with a USB Serial driver. Make sure that in the Options tab "List All devices" is checked and "Ignore Hubs or Composite Parents" is unchecked. Then select "MX10/Spider MCU (Composite Parent)" and USB Serial (CDC) and click "Replace Driver".
