gailu Posted February 14, 2017 Share Posted February 14, 2017 Hi Experts, I am using Armbian Ubuntu Xenial image on Orange Pi Zero. Board boots fine every time when serial console is connected without pressing any key. However booting stuck most of the time at (Loading, please wait...) when no serial console is connected. We have to connect serial console and press enter every time it gets stuck and then booting proceeds further as usual. Any idea what might be wrong. Logs when serial console is connected and not key is pressed during boot U-Boot SPL 2017.01-armbian (Feb 02 2017 - 03:04:34) DRAM: 512 MiB Trying to boot from MMC1 U-Boot 2017.01-armbian (Feb 02 2017 - 03:04:34 +0100) Allwinner Technology CPU: Allwinner H3 (SUN8I 1680) Model: Xunlong Orange Pi Zero DRAM: 512 MiB MMC: SUNXI SD/MMC: 0 *** Warning - bad CRC, using default environment In: serial Out: serial Err: serial Net: phy interface0 eth0: ethernet@1c30000 Hit any key to stop autoboot: 0 6944 bytes read in 159 ms (42 KiB/s) switch to partitions #0, OK mmc0 is current device Scanning mmc 0:1...

gailu Posted February 14, 2017 Author Share Posted February 14, 2017 Our system in the field will not have console connected and it is impossible to release with this issue as it just keeps waiting any key to press. Looking for directions to resolve. Have no clue why it keeps waiting for key press to move forward. Link to comment Share on other sites More sharing options...
gailu Posted February 15, 2017 Author Share Posted February 15, 2017 Any directions what the kernel waits for before we get log "starting version 229"? and what are possible reasons that without console connected boot progress stop just before this print and moves ahead only when we connect console and press enter. FYI: I am using overlayroot on Ubuntu xenial where I see this behaviour Link to comment Share on other sites More sharing options...
gailu Posted February 15, 2017 Author Share Posted February 15, 2017 Made the progress so just to update/close this thread. It looks like some issue if the wires are connected to FTDI USB TTL and USB is plugged out from laptop. If console wires are detached altogether from OPI Zero, then it boots fine.

martinayotte Posted February 15, 2017 Share Posted February 15, 2017 This is because USB-TTL been un-powered, it acts like a Pull-Down on the RX signal, which is seen as BREAK condition. Never leave a USB-TTL on header when not in use. Link to comment Share on other sites More sharing options...
hajime Posted October 8, 2017 Share Posted October 8, 2017 This is very late reply. I faced almost same problem with OP Zero. Ubuntu, Debian both were same. I used compressed air and blow OP Zero, the problem is settled. I use heat conductive grease to install heat sink. it seems extra dried grease outside the sink dropped on the board.
