Run benchmark on any attached storage device (e.g. eMMC, microSD, NVMe, SATA) and add results under an additional heading. Download the script with curl -o disk-benchmark.sh [URL_HERE] and run sudo DEVICE_UNDER_TEST=/dev/sda DEVICE_MOUNT_PATH=/mnt/sda1 ./disk-benchmark.sh (assuming the device is sda).

Also consider running PiBenchmarks.com script.

One fun issue I've run into: I can't detect events like rising or falling edge (so gpiomon won't work) with the default Raspbian OS image. I can't seem to get it working with Armbian either, even though Libre computer says there should be a patch there for gpio_to_irq to make it work (you can only do up to 8 devices).

I also had trouble using the i2c bus with a relay HAT, but found from this forum thread that I needed to manually grab and compile the overlay for the i2c bus from Libre Computer's own wiring project:

wget https://raw.githubusercontent.com/libre-computer-project/libretech-wiring-tool/master/libre-computer/aml-s905x-cc/dt/i2c-ao.dts
sudo armbian-add-overlay i2c-a.dts  # this compiles the overlay into /boot/overlay-user/i2c-a.dtbo
sudo reboot

And after that, I see the bus with i2cdetect:

pi@lepotato:~$ i2cdetect -l
i2c-0   i2c         Meson I2C adapter                   I2C adapter
i2c-1   i2c         DesignWare HDMI                     I2C adapter

To shutdown the board, you can't just run sudo shutdown now or sudo poweroff, you have to run sudo shutdown -H now to really halt it (otherwise it'll just reboot).

Not too stale.

Hi @geerlingguy

The IRQ stuff has been fixed on the latest 6.1.57 kernel on our images.
Shutdown auto-restart was disabled a few months ago.
We added support low power suspend state and resume.
Wake from shutdown/suspend by UART RX activity, Magic Packet, IR (code not configurable yet but we might do it in the future), or by pulling GPIOH_6 to ground.

Thanks for bring up the issues. Let us know if you run into any other issues.

@dsx724 - That's awesome, thank you so much!
