2 First Steps

This chapter provides instructions for getting the PX30-uQ7 EVK running after opening the box.

Insert the PX30-uQ7 module at a 30-degree angle into the connector in the base board. Once fully inserted, push it down until

it rests on the standoffs and check alignment of the mounting holes.

Note: The module springs back into the 30-degree angle once released. This is expected, and alignment will be kept. The

module will be secured into place.

The fan is only necessary in exceptionally high ambient temperatures. Under normal conditions, the PX30 operates passively

cooled.

For bootloader configuration and Linux console, the serial interface can be used. Connect either a Micro-USB or RS-232

cable to the corresponding port. Select the correct UART with UART selector slider (1). For Micro-USB, the slider has to be

in the right position to route the default console (UART0) to the USB-UART bridge. For RS-232, the slider has to be in the left

position and the protocol slider (2) has to be in the RS-232 position (see Fig. 2.2 Serial console and boot configuration ).

Connect the power supply and verify the sliders are in the position Normal Boot (3) and Normally Off (4). Press the Power

Button (5) to power the board. You will see the boot progress and later on a login prompt on the serial interface. If the display

is connected, video output will follow shortly after.
