- Some eMMC modules might not work well.
- Recent batch (since mid-2022) seem to have shipped with a different bootloader configuration, some times preventing booting from SD card and/or eMMC. Until a proper fix can be implemented, the recommended workaround is to install a bootloader to SPI. Further details and instructions can be found in this forum thread.
- USB3 sometimes doesn’t detect high-speed devices properly
- UART is accessible on pin 6 (GND),8 (TX) and 10 (RX) and with unusual speed: 1500000
- flash the 128M SPI memory to also boot from USB or PXE (it if goes wrong, follow these instructions)
- short-pressing (~1s) the power button turns the board on, long-pressing it (~3s) turns it off. If it gets stuck while halting, press the reset button. If it does not boot (ie the white led does not come up), reset, then power on.
- if you experience USB3 storage lack of reliability (error messages followed by filesystem corruption), check your power supply, usb cable and connectors and disk/ssd. All these factors can lead to undervoltage issues (some ssd could produce power consumption spikes triggering undervoltage).
- Supported 720 and 1080p model,
- DVFS, battery and brightness control,
- MALI with opensource Lima drivers,
- Chromium web-dl enabled,
- not enabled or not tested: suspend/resume
- UART is accessible on pin 6 (GND),8 (TX) and 10 (RX) and with unusual speed: 1500000
- Video and 3D acceleration addon
- Clocking to maximum safe CPU speed (1.51Ghz) is possible this way:
sed -i "s/MAX_SPEED=.*/MAX_SPEED=1510000/" /etc/default/cpufrequtils service cpufrequtils restart
Make sure to install large heatsink!
