Port Description


Level shifting/MUX

In this Firmware Version CRUVI Low Speed connector CA has four signals configured as input and another four as output. Depending on the connectors and signals used/needed this can be changed by customizing and updateing the firmware. Also the 3.3V signals on the three CRUVI High Speed connectors can be utilized in that way. See TEB0707 CPLD Firmware.

X0 <= M_G1_01 ;
X2 <= M_G1_02 ;
X4 <= M_G1_03 ;
X6 <= M_G1_04 ;

M_G1_05 <= X1;
M_G1_06 <= X3;
M_G1_07 <= X5;
M_G1_08 <= X7;

JTAG/ UART forward to 4x5 module

JTAG

Switch with hard wired JTAGEN Dip4 between user mode of pins, which corresponds due to the lines below to SoM JTAG ("OFF", open, 'low') and Max10 CPLD ("ON", closed, 'high')

TDO <= M_TDO;
M_TMS <= TMS;
M_TCK <= TCK;
M_TDI <= TDI;

UART

M_G6_01 <= F_UART_TX; --TX UART to SoM
F_UART_RX <= M_G6_02; --RX UART from SoM

Module control pins

RESIN <= BUTTON0; -- reset SoM
NOSEQ <= net_gnd; -- powermanagement by CPLD is NOT disabled
PROGMODE <= not(DIP3); -- select between CPLD (low, closed, on) on SoM or FPGA/SoC (high, open, off )
EN1 <= net_vcc; --module power always enabled
MODE <= SD_CD ; -- select SD boot mode when card installed ('low'), else QSPI ('high')

Button and Dips

User Button

User button on PL is debounced:
M_G1_20 <= Button1_db;

User Dips:

Dip1 is directly forwarded to a PL IO:
M_G1_16 <= not(DIP1);

Dip2 is used for IO Voltage selection, see IO Voltage selection.
Dip3 is used for JTAG selection, see Module control pins.


LEDs

Status LEDs

The LED D7 and D8 are utilized for board status and power information in the following way:

Sequenz
Description D7 (red)Description D8 (green)
OFFLED OFFPower OKcurrently not used
*ooooooo1 times blinking with a breakSoM Power error (PGOOD 'low' or M3_3VOUT  'low')currently not used
**oooooo to ****oo2, 3, 4 times blinking with a breakcurrently not usedcurrently not used
*****ooo5 times blinking with a breakUSB power errror (USB_OC 'low)SoM CPLD JTAG enabled
******oo to ********6, 7, 8 times blinking with a breakcurrently not usedcurrently not used
ONLED ONcurrently not usedSystem OK
Status LEDs description
USR LEDs

User LEDs D1, D2, D3 (green) are connected to PL IOs:

LED3 <= M_G1_19;
LED2 <= M_G1_18;
LED1 <= M_G1_17;


User LEDs D4, D5, D6 (red) are connected to IOs which are located at PL or PS  depending on SoM.

LED4 <= M_G6_04;
LED5 <= M_G6_07;
LED6 <= M_G6_08;

ETH LEDs

Ethernet Jack LEDs are not used in this firmware and are therefore tied to GND.

ETH_LED2 <= net_gnd;
ETH_LED1 <= net_gnd;

Power sequenzing

The M3.3VOUT signal of the SoM is used to Enable  CRUVI power rails  and the SOM IO Voltage:

EN_C5VIN <= M3_3VOUT;
EN_C3_3V <= M3_3VOUT;
EN_IOV <= M3_3VOUT;

IO Voltage selection

Select IOV Voltage of DCDC U3:

VS0 <= not(DIP2);
VS1 <= DIP2;
VS2 <= net_gnd;

"010" selects 1.8V (Dip2 open, "OFF", 'high'). 
"001" selects 2.5V (Dip2 closed, "ON", 'low').

WEEE

Information for users within the European Union in accordance with Directive 2002/96/EC of the European Parliament and of the Council of 27 January 2003 on waste electrical and electronic equipment (WEEE).

Users of electrical and electronic equipment in private households are required not to dispose of waste electrical and electronic equipment as unsorted municipal waste and to collect such waste electrical and electronic equipment separately. By the 13 August 2005, Member States shall have ensured that systems are set up allowing final holders and distributors to return waste electrical and electronic equipment at least free of charge. Member States shall ensure the availability and accessibility of the necessary collection facilities. Separate collection is the precondition to ensure specific treatment and recycling of waste electrical and electronic equipment and is necessary to achieve the chosen level of protection of human health and the environment in the European Union. Consumers have to actively contribute to the success of such collection and the return of waste electrical and electronic equipment. Presence of hazardous substances in electrical and electronic equipment results in potential effects on the environment and human health. The symbol consisting of the crossed-out wheeled bin indicates separate collection for waste electrical and electronic equipment.
