Flylead

This MIB allow to connect and test any DUT as the MIB expose every connectors available.

Header pinout

The flylead header pinout is defined as below:

	A	B
1	SIB_UART4_RX	GND
2	SIB_UART4_TX	GND
3	DDT_GPIO_6	DDT_GPIO_8
4	DDT_GPIO_7	DDT_GPIO_9
5	SIB_UART1_RX	SIB_UART3_TX
6	SIB_UART1_TX	SIB_UART3_RX
7	SIB_UART1_RTS	GND
8	SIB_UART1_CTS	GND
9	I2C_MIB_VIO_SDA	I2C_SIB_3V3_SDA
10	I2C_MIB_VIO_SCL	I2C_SIB_3V3_SCL
12	DDT_MOSI	DDT_MISO
12	DDT_SCK	GND
13	DDT_CS	DDT_GPIO_2
14	GND	GND
15	DDT_GPIO_1	DUT_OPTO_2E
16	GND	DUT_OPTO_2C
17	DDT_GPIO_3	DUT_OPTO_1E
18	GND	DUT_OPTO_1C
19	DDT_GPIO_4	DUT_PWR
20	DDT_GPIO_5	DUT_RST

USB ports

USB ports

The two USB ports on the flylead MIB are always ON and cannot be controlled from the software.

If you need a switchable USB port, use one of the 4 ports on the SIB.

Software usage

CAN

The CAN bus is available as can0 network interface. Use any CAN aware tools like can-utils to interact on the bus.

GPIOs

Two gpios are available to toggle buttons. They can be controlled with:

laam laacli button reset on
laam laacli button reset off

The available GPIOs are:

DUT_RST: reset button
DUT_PWR: power button

I²C

The header provides 2 I²C:

I2C_SIB_3V3_SCL and I2C_SIB_3V3_SDA at 3v3
I2C_MIB_VIO_SCL and I2C_MIB_VIO_SDA at MIB_VIO reference voltage (from 0V to 5V).

Optocouplers

Two optocouplers are available to toggle on and off virtual buttons. The buttons can be controlled with:

laam laacli button 1 on
laam laacli button 1 off

The available optocouplers are:

DUT_OPTO_1C and DUT_OPTO_1E: virtual button 1
DUT_OPTO_2C and DUT_OPTO_2E: virtual button 2

Power rails

Each power rail is available via screw terminal and can be controlled by laam:

laam laacli power 12v on
laam laacli power 12v off
laam laacli power 12v reset

The MIB provides access to the 4 power rails: 1v8, 3v3, 5v and 12v.

Delivered power

The power rail maximum power are listed in this table:

Power rail	Max Amp (A)	Max Power (W)
1v8	1A	1.8W
3v3	2A	6.6W
5v	3A	15W
12v	3A	36W

Power rails power

The instant power consumption of each power rail is monitored and can be queried by laam:

laam laacli watt 12v
laam laacli watt 3v3

Serials

The header provides 3 set of serials:

SIB_UART1 as /dev/ttycmx0: DUT serial with hardware flow control
SIB_UART3 as /dev/ttycmx2: LAA serial
SIB_UART4 as /dev/ttycmx3: DUT serial

SIB_UART4 is also available via laam or telnet:

laam serials connect ttymxc3
telnet localhost 2000

SPI

The header provides one SPI: DDT_CS, DDT_SCK, DDT_MISO and DDT_MISO.
