A Pi2B v1.1 running FreeBSD www.zefox.com 13.0-CURRENT FreeBSD 13.0-CURRENT #1 main-c634-gd03fd8ede2: Wed Jan 6 00:37:38 PST 2021 bob@www.zefox.com:/usr/obj/usr/freebsd-src/arm.armv7/sys/GENERIC-MMCCAM arm generates a flurry of output seemingly related to mass storage. It seems indicative of some sort of communications problem, but the machine boots and runs when all is said and done. This isn't new behavior and is common to a Pi3 running arm64 in large part. Seeming errors, all of which eventually just go away, include Bus usb@7e980000: scanning bus usb@7e980000 for devices... unable to get device descriptor (error=-22) and a flurry of (da0:umass-sim0:0:0:0): daclose (da0:umass-sim0:0:0:0): daopen messages, which eventually just go away. There is also much chatter related to (mmcprobe0:sdhci_slot0:0:0:0): mmcprobe_start ..... but I believe that's correct and related to MMCCAM, present in the kernel but (I think) absent in the Pi2B (not +) hardware. MMCCAM was added in response to a request on the mailing list for testing. A complete transcript taken from the serial console is at http://www.zefox.net/~fbsd/rpi2/success/20210106/bootlog The system is a Pi2 V1.1 with its boot file system on an old USB2 hard disk connected via powered hub. The microSD carries an msdos partition containing drwxr-xr-x 1 root wheel 4096 Jul 2 2020 EFI -rwxr-xr-x 1 root wheel 25265 Nov 22 2019 bcm2709-rpi-2-b.dtb -rwxr-xr-x 1 root wheel 52304 Nov 22 2019 bootcode.bin -rwxr-xr-x 1 root wheel 89 Jul 2 2020 config.txt drwxr-xr-x 1 root wheel 8192 Jul 2 2020 dtb -rwxr-xr-x 1 root wheel 6744 Nov 22 2019 fixup.dat -rwxr-xr-x 1 root wheel 2655 Nov 22 2019 fixup_cd.dat -rwxr-xr-x 1 root wheel 9816 Nov 22 2019 fixup_db.dat -rwxr-xr-x 1 root wheel 9816 Nov 22 2019 fixup_x.dat drwxr-xr-x 1 root wheel 4096 Jul 2 2020 overlays -rwxr-xr-x 1 root wheel 2880356 Nov 22 2019 start.elf -rwxr-xr-x 1 root wheel 688068 Nov 22 2019 start_cd.elf -rwxr-xr-x 1 root wheel 4857160 Nov 22 2019 start_db.elf -rwxr-xr-x 1 root wheel 3794600 Nov 22 2019 start_x.elf -rwxr-xr-x 1 root wheel 457716 Jul 2 2020 u-boot.bin -r-xr-xr-x 1 root wheel 392216 Jul 2 2020 ubldr.bin The remainder of the microSD carries only a 1 GB swap partition. There is neither mouse nor keyboard. Thanks for reading, and any thoughts on the odd-looking messages. bob prohaska
