Devices on SOM

QSPI Flash

  • Size : 512MB
    Storage for boot firmware which file name is BOOT.BIN.

eMMC

  • Size : 16GB
    Storage for Images, there should be two partition boot and root in eMMC.

DDR4

  • Size : 4GB
  • Speed : DDR4_2400R

TPM2.0 Security Module

  • Vendor :　infineon

SOC

  • Part Name : xck26-sfvc784-2lv-c
  • Zynq UltraScale+
    This series FPGA are also called as zynqmp. It contain two main part:
  • Processing System (PS)
    • CPU CortexA53 * 4
    • GPU Mali400
    • IO (MIO)
  • Programmable Logic (PL)
    • Video codec (VCU)
    • Logic gates
    • IO (EMIO)

Carrier Board Overview

  • Following shows the overview of A4 version of carrier board, double check the IO or switch location if not the same version, there might have some rotation or shifting.

IO on Carrier Board

There are two types of IO PS & PL on carrier board, IO which from PS will be always avalible, but IO which from PL will be only avalible when FPGA with firmware include this IO.

Processing System (PS)

  • LAN
  • USB
  • HDMI
  • SD Card
  • eMMC
  • UART0
  • M.2 EKEY PCIE Gen2x1

Programmable Logic (PL)

  • M.2 MKEY PCIE Gen3x4
  • CAN0
  • CAN1
  • GPIO
  • I2C

Switchs on Carrier Board

SW5

SW5-1

  • Function : HDB IO voltage Level switch, default off to 1.8V, switch on to 3.3V.
  • HDB including GPIO0, GPIO1, GPIO2
  • Suggest using 1.8V.

SW5-2

  • Function : HDC IO voltage Level switch, default off to 1.8V, switch on to 3.3V.
  • HDC including GPIO3, GPIO4
  • Suggest using 1.8V.

SW5-3

  • Function : Power button on switch, default off for auto power on.

SW5-4

  • Function : I2C voltage Level switch for different IO bank, default off to 1.8V, switch on to 3.3V.
  • Suggest using 1.8V.

Debug board

debug_board.png Debug Board include three main function:

  • Debug UART
  • JTAG
  • HDMI UART

Debug UART

  • Baud rate : 115200
  • Function : Main interactive interface for developer, it could be access by serial port utilities like minicom, putty, mobaxterm.

JTAG

JTAG won't work if EEPROM on debug board didn't contain correct info.

  • Function : JTAG for xilinx IDE.

HDMI UART

Direct connect into HDMI splitter which on carrier board.

  • Baud rate : 115200
  • Function : Flash firmware for HDMI splitter.
