I suspect/fear that the answer might be, "your hardware died", but since the armv7 port is under heavy development, maybe this information will be of some value to the devs...
I've been running snapshots on my Wandboard Quad for the past few weeks without incident. Sometime yesterday or last night, the system went down (no response to pings or serial console) and wouldn't boot back up. I pulled the SD card and mounted it in a working machine, and found nothing in the logs indicating what might have gone wrong. Both bsd and bsd.rd hang during boot, with this as the last line of dmesg: simplebus5 at mainbus0: "regulators" >From previous successful boots, this should be followed by: scsibus1 at sdmmc2: 2 targets, initiator 0 sd0 at scsibus1 targ 1 lun 0: <SD/MMC, 00000, 0010> SCSI2 0/direct fixed sd0: 61056MB, 512 bytes/sector, 125042688 sectors vscsi0 at root scsibus2 at vscsi0: 256 targets softraid0 at root scsibus3 at softraid0: 256 targets boot device: sd0 root on sd0a (3c60000fd48d06a0.a) swap on sd0b dump on sd0b WARNING: CHECK AND RESET THE DATE! While I had the SD card out, I copied over the latest snapshot bsd.rd, which also hangs at the same point. As I said, I suspect bad hardware. The only reason why I suspect there *might* be a software issue is that the machine has had nothing but warm boots for the past few weeks. I pulled the power plug to reset the machine this morning, and that's the first time it's had a cold boot since the initial installation. Maybe something's not initializing properly from a cold boot? Is there anything worthwhile I can provide to the developers before pursuing warranty replacement? Following is the complete dmesg, up to the point of hanging: Connected to /dev/cuaU0 (speed 115200) U-Boot SPL 2016.07 (Aug 06 2016 - 00:03:39) Trying to boot from MMC1 U-Boot 2016.07 (Aug 06 2016 - 00:03:39 -0600) CPU: Freescale i.MX6Q rev1.5 at 792 MHz Reset cause: POR Board: Wandboard rev C1 I2C: ready DRAM: 2 GiB MMC: FSL_SDHC: 0, FSL_SDHC: 1 *** Warning - bad CRC, using default environment No panel detected: default to HDMI Display: HDMI (1024x768) In: serial Out: serial Err: serial Net: FEC [PRIME] Hit any key to stop autoboot: 0 switch to partitions #0, OK mmc0 is current device Scanning mmc 0:1... reading /imx6q-wandboard.dtb 32385 bytes read in 19 ms (1.6 MiB/s) Found EFI removable media binary efi/boot/bootarm.efi reading efi/boot/bootarm.efi 65276 bytes read in 27 ms (2.3 MiB/s) ## Starting EFI application at 0x12000000 ...
