November 14, 2025Nov 14 Author Hi @djurny Just to inform you that, after cleaning out some mess I made, your overlay and armbianEnv.txt update to make the external RTC ds3231 to work, did the job. For my SBC's I use the Banana Pi M2 Zero and v25.5 rolling for Banana Pi M2 Zero running Armbian Linux 6.6.75-current-sunxi My application needs to work in the field as an Access Point with an RTC, the right date and time is important info in the diagnostics of my applications. A remark on the mentioned Armbian release: For using the GPIO pins of the SBC, python3-libgpiod works great. I use USB camera's (V4L2 camera). After any update or upgrade, my USB camera's won't work anymore. Not really a problem for me, because I'm happy as it works right now, no updates or upgrades needed. Thanks again for your great help. Met vriendelijke groet, Ed Edited November 14, 2025Nov 14 by Ed van den Enden
