OSM-IMX93

Enablement

LAVA by default is configured to work with this DUT + LAA setup. If you opt for a different setup you’ll have to change your DUT + LAA device configuration on LAVA.

For our OSM-IMX93 setup we make use of the I-Pi OSM-IMX93, which can be automated using the Flylead boards MIB.

Components

The following components are required to fully automate the board:

  • Flylead boards MIB

  • Short RJ45 network cable

  • USB-A male to MicroUSB male cable

  • USB-A male to USB-C male cable

  • Micro SD Card

  • 2.5/5.5mm barrel jack to MIB 2-pin connector, wired centre positive

  • 4x jumper wires

Hardware modification

In order to automate recovery, the DUT hardware should be modified.

Hardware modification

The DUT will not be automatizable without this modification.

Boot Select switches

A 2x jumper wires cable has to be soldered around SW7 and connected on the Flylead to V Button 1. Another 2x jumper wires cable has to be soldered around SW8 and connected on the Flylead to V Button 2. The polarity for both jumper wires cables doesn’t matter. This will be used to short circuit the ends of the switches and change the boot mode as we want.

Recovery

Connect the recovery SW7 wires cable to the Flylead MIB header labeled V Button 1. Connect the recovery SW8 wires cable to the Flylead MIB header labeled V Button 2.

Network

Connect the OSM-IMX93 network interface to the LAA private network interface as indicated above.

Power

The OSM-IMX93 gets power from the 2.5/5.5mm barrel jack connected to the board and the 12V header on the MIB.

Serial

Connect a USB cable from the carrier board USB-C port to USB Port 3 on the LAA as shown above.

Flashing

Connect a cable from the USB-A LAA USB Port 2 (facing upward) to the OSM-IMX93 MicroUSB Port shown in the picture above.

USB

Connect the LAA USB OTG port (front facing) to the OSM-IMX93 USB-A Port shown in the picture above.

SD Card

Please take an SD Card of at least 16Gb and format it. Then insert it in the SD card slot on the OSM-IMX93 board.
