Xilinx SmartLynq Plus User Manual

The <direcon> is an 8-bit hexadecimal value. Bits set to 1 in the <direcon> eld are set as
outputs. Otherwise the pin is used as an input. The second oponal value argument is used for
specifying how to drive the pins that are set as outputs. Note that seng the direcon to 0x
makes all pins outputs. The following is an example of how to use this command when logged in
over ssh:
sudo /opt/xilinx/bin/update_hw_gpio 0x3f 0xe7
This does the following:
•
<direcon> 0x3f sets pin 0 to 5 as outputs; 6 and 7 as inputs
•
<value> 0xef sets the output values: pin 0 = 1, pin 1 = 1, pin 2 = 1, pin 3 = 0, pin 4 = 0, pin 5 =
1
