Description

TI BoosterPack GPIO header

GPIO pins exposed as BoosterPack headers on TI LaunchPads.

BoosterPack plug-in modules are available in 20 and 40 pin variants. The
20 pin variant has two 10 x 1 pin headers and the 40 pin variant has two
10 x 2 pin headers. Both variants are compatible and stackable.

The pins of the 20 pin variant and the outer row of the 40 pin variant are
numbered 1 through 20. The inner rows of the 40 pin variant are numbered 21
through 40. The BoosterPack pinout is depicted below:

1  3.3V     21 5V                    40 GPIO 20 GND
2  Analog   22 GND                   39 GPIO 19 GPIO / SPI CS
3  UART RXD 23 Analog                38 GPIO 18 GPIO
4  UART TXD 24 Analog                37 GPIO 17 GPIO
5  GPIO     25 Analog                36 GPIO 16 RESET
6  Analog   26 Analog                35 GPIO 15 SPI MOSI
7  SPI CLK  27 Analog                34 GPIO 14 SPI MISO
8  GPIO     28 Analog                33 GPIO 13 GPIO / SPI CS
9  I2C SCL  29                       32 GPIO 12 GPIO / SPI CS
10 I2C SDA  30                       31 GPIO 11 GPIO

status

string

 
indicates the operational status of a device

Legal values: 'ok', 'okay', 'disabled', 'reserved', 'fail', 'fail-sss'

See Important properties for more information.

string-array

 
name of each register space

interrupts

array

 
interrupts for device

See Important properties for more information.

wakeup-source

boolean

 
Property to identify that a device can be used as wake up source.

When this property is provided a specific flag is set into the
device that tells the system that the device is capable of
wake up the system.

Wake up capable devices are disabled (interruptions will not wake up
the system) by default but they can be enabled at runtime if necessary.

power-domain

phandle

 
Power domain the device belongs to.

The device will be notified when the power domain it belongs to is either
suspended or resumed.
