Using Android Debug Bridge (adb) for Remote Access and File Transfers¶
Android Debug Bridge (adb) is the default recommend way to transfer files to the MitySOM-QC6490.
Development Board Configuration¶
Ensure that Switch S7 is set properly.- Switch 1 should be set to enable the USBC, which is a top level enable to send 1.8 V for USB-C
- Switch 2 can be either set or not set
- If Switch 2 is not set the 1.8V comes from the DC supply on the Development Kit
- If Switch 2 is set the 1.8V comes from the SOM

Prerequisites¶
To use adb with the QC SOM, first ensure you have adb installed on the host PC. This can be achieved via:- Your host PC's package repository, if applicable.
- For example, on Ubuntu (tested on 18.04 and 24.04) you can run
sudo apt install adb android-sdk-platform-tools-common
- For example, on Ubuntu (tested on 18.04 and 24.04) you can run
- Android's downloads page (not tested)
- Additionally, on Linux platforms, determine whether you need to create additional udev rules.
Setup¶
- Plug in a USB cable (either USB-A to USB-C or USB-C to USB-C) between the host PC and dev kit's USB-C port (J6). Note: Ensure the SOM is NOT booted prior to plugging in the USB.
- Boot the SOM and then, from the host PC, run
adb devices. This should start adb and detect any available devices automatically.- Example of successful connection:
$ adb devices * daemon not running; starting now at tcp:5037 * daemon started successfully List of devices attached f4b115d2 device
- Example of successful connection:
- Note that all transfers and access are requested from the host PC
- To send data the host PC to the MitySOM-QC6490 try the following:
adb push <source> <destination>
- Note:
sourceis the path on the host PC of the file to be transferred to the MitySOM-QC6490. - Note:
destinationis the path on the MitySOM-QC6490 where the file is to be written.
- Note:
- To send data the MitySOM-QC6490 to the host PC to try the following:
adb pull <source> <destination>
- Note:
sourceis the path on the MitySOM-QC6490 of the file to be transferred to the host PC. - Note:
destinationis the path on the host PC where the file is to be written.
- Note:
- To achieve remote console access to the MitySOM-QC6490 try the following:
adb shell
- To send data the host PC to the MitySOM-QC6490 try the following:
- Note: Once the SOM is booted, do not disconnect the USB-C connection. If you do, you may need to power off the SOM and repeat this procedure to reconnect.
Debug¶
If you have any issues with connecting adb, try the following:- Disconnect the USB-C, power cycle the SOM, reconnect the USB, and boot the SOM again.
- Try different ports on the host PC and/or try different USB cables.
