USB armory Mk II: Revision 31
This page describes pre-prelease version of usb armory, so if you are receiving release version, I had wrong expectations from this board: I was hoping to be able to use GPIO for serial or connecting sensors and that is not possible.

boot select switchSwitch near sdcard select booting from emmc or microsd (silkscreen is somewhat poor, but by default bafore removing sticker it will boot from sdcard) If it's closer to sdcard, it will boot from sdcard image delivered on devicePassword for image delivered with device is not usbarmory (?) In fact, it doesn't have usbarmory user in /etc/passwd, but has it in /etc/shadow, go figure! root@usbarmory:/# cat /etc/passwd root:x:0:0:root:/root:/bin/bash daemon:x:1:1:daemon:/usr/sbin:/usr/sbin/nologin bin:x:2:2:bin:/bin:/usr/sbin/nologin sys:x:3:3:sys:/dev:/usr/sbin/nologin sync:x:4:65534:sync:/bin:/bin/sync games:x:5:60:games:/usr/games:/usr/sbin/nologin man:x:6:12:man:/var/cache/man:/usr/sbin/nologin lp:x:7:7:lp:/var/spool/lpd:/usr/sbin/nologin mail:x:8:8:mail:/var/mail:/usr/sbin/nologin news:x:9:9:news:/var/spool/news:/usr/sbin/nologin uucp:x:10:10:uucp:/var/spool/uucp:/usr/sbin/nologin proxy:x:13:13:proxy:/bin:/usr/sbin/nologin www-data:x:33:33:www-data:/var/www:/usr/sbin/nologin backup:x:34:34:backup:/var/backups:/usr/sbin/nologin list:x:38:38:Mailing List Manager:/var/list:/usr/sbin/nologin irc:x:39:39:ircd:/var/run/ircd:/usr/sbin/nologin gnats:x:41:41:Gnats Bug-Reporting System (admin):/var/lib/gnats:/usr/sbin/nologin nobody:x:65534:65534:nobody:/nonexistent:/usr/sbin/nologin systemd-timesync:x:100:102:systemd Time Synchronization,,,:/run/systemd:/bin/false systemd-network:x:101:103:systemd Network Management,,,:/run/systemd/netif:/bin/false systemd-resolve:x:102:104:systemd Resolver,,,:/run/systemd/resolve:/bin/false systemd-bus-proxy:x:103:105:systemd Bus Proxy,,,:/run/systemd:/bin/false _apt:x:104:65534::/nonexistent:/bin/false messagebus:x:105:108::/var/run/dbus:/bin/false sshd:x:106:65534::/run/sshd:/usr/sbin/nologin interlock:x:1000:1000::/home/interlock:/bin/bash lcars:x:1001:1001::/home/lcars:/bin/bash root@usbarmory:/# cat /etc/shadow root:*:18068:0:99999:7::: daemon:*:18068:0:99999:7::: bin:*:18068:0:99999:7::: sys:*:18068:0:99999:7::: sync:*:18068:0:99999:7::: games:*:18068:0:99999:7::: man:*:18068:0:99999:7::: lp:*:18068:0:99999:7::: mail:*:18068:0:99999:7::: news:*:18068:0:99999:7::: uucp:*:18068:0:99999:7::: proxy:*:18068:0:99999:7::: www-data:*:18068:0:99999:7::: backup:*:18068:0:99999:7::: list:*:18068:0:99999:7::: irc:*:18068:0:99999:7::: gnats:*:18068:0:99999:7::: nobody:*:18068:0:99999:7::: systemd-timesync:*:18068:0:99999:7::: systemd-network:*:18068:0:99999:7::: systemd-resolve:*:18068:0:99999:7::: systemd-bus-proxy:*:18068:0:99999:7::: _apt:*:18068:0:99999:7::: messagebus:*:18068:0:99999:7::: sshd:*:18068:0:99999:7::: usbarmory:$6$rcyB4m4EPv$udqWloCZH/Av1IkJVuZHyWMhw/fYkhLGevlo17C3x6qMemSHUmPPAQrvc0SaY.yWVIIU0ADL0g54MZmidcxFn.:18068:0:99999:7::: lcars:$6$iFljmotV$gnK66oZpz7BD3BqlFpPWoY/Q1tey8in75868neosxypKswjSoNDQotiMBZ9hh.vQBDyltA08z2Vji/QjElv4g.:18072:0:99999:7::: interlock:!:18072:0:99999:7::: After adding usbarmory account, running apt upgrade (since image has old kernel) device isn't bootable any more (at least it's not detected by host in which it's plugged in). Let's try to rebuild image for emmc and flash it. Well, re-build fails with patches allready applied errors in linux source, so let's wipe it: root@813046ba7c77:/opt/armory# rm -Rf linux-* u-boot-2019.07* root@813046ba7c77:/opt/armory# make all V=mark-two IMX=imx6ull BOOT=eMMC -j 8 pads on boardthere is kicad project of production one which just removed pads https://github.com/f-secure-foundry/usbarmory/tree/master/hardware/mark-two
from changelog those pads might be jtag (since it's enabled in u-boot), but schematics confirms it. It seems that 8 gpio pins are available using additional board: https://github.com/inversepath/usbarmory/tree/master/hardware/mark-two-debug-accessory sdcard vs emmc speedroot@usbarmory:/mnt/klin/home/dpavlin/usb-armory/usbarmory-debian-base_image# hdparm -Tt /dev/mmcblk[01] /dev/mmcblk0: # -- sdcard Timing cached reads: 664 MB in 2.00 seconds = 331.99 MB/sec Timing buffered disk reads: 34 MB in 3.03 seconds = 11.21 MB/sec /dev/mmcblk1: # -- emmc Timing cached reads: 716 MB in 2.00 seconds = 357.40 MB/sec Timing buffered disk reads: 128 MB in 3.04 seconds = 42.17 MB/sec communityhttps://groups.google.com/forum/#!forum/usbarmory led heartbeat offhttps://photos.app.goo.gl/rRrzfbbs4GGjt3ePA very bright and annoying in dark room sbarmory@usbarmory:/sys/class/leds/LED_WHITE$ cat trigger none kbd-scrolllock kbd-numlock kbd-capslock kbd-kanalock kbd-shiftlock kbd-altgrlock kbd-ctrllock kbd-altlock kbd-shiftllock kbd-shiftrlock kbd-ctrlllock kbd-ctrlrlock mmc0 mmc1 cpu cpu0 [heartbeat] root@usbarmory:/sys/devices/soc0/leds/leds/LED_WHITE# echo none > trigger network speedroot@usbarmory:~# iperf3 -c 10.0.0.2 Connecting to host 10.0.0.2, port 5201 [ 4] local 10.0.0.1 port 33574 connected to 10.0.0.2 port 5201 [ ID] Interval Transfer Bandwidth Retr Cwnd [ 4] 0.00-1.03 sec 23.0 MBytes 188 Mbits/sec 0 174 KBytes [ 4] 1.03-2.00 sec 20.6 MBytes 178 Mbits/sec 0 272 KBytes [ 4] 2.00-3.01 sec 21.1 MBytes 176 Mbits/sec 0 286 KBytes [ 4] 3.01-4.01 sec 21.8 MBytes 182 Mbits/sec 0 297 KBytes [ 4] 4.01-5.00 sec 20.1 MBytes 171 Mbits/sec 0 297 KBytes [ 4] 5.00-6.00 sec 21.0 MBytes 176 Mbits/sec 0 329 KBytes [ 4] 6.00-7.00 sec 20.3 MBytes 171 Mbits/sec 0 329 KBytes [ 4] 7.00-8.00 sec 20.4 MBytes 171 Mbits/sec 0 329 KBytes [ 4] 8.00-9.00 sec 20.3 MBytes 171 Mbits/sec 0 329 KBytes [ 4] 9.00-10.00 sec 20.1 MBytes 169 Mbits/sec 0 329 KBytes - - - - - - - - - - - - - - - - - - - - - - - - - [ ID] Interval Transfer Bandwidth Retr [ 4] 0.00-10.00 sec 209 MBytes 175 Mbits/sec 0 sender [ 4] 0.00-10.00 sec 208 MBytes 174 Mbits/sec receiver iperf Done. network setup for desktopdpavlin@nuc:~$ grep usbarmory -A 5 /etc/network/interfaces # usbarmory allow-hotplug enx1a5589a26942 iface enx1a5589a26942 inet static address 10.0.0.2 netmask 255.255.255.0 post-up iptables -t nat -A POSTROUTING -s 10.0.0.0/24 -o eth0 -j MASQUERADE bluetoothhttps://github.com/inversepath/usbarmory/wiki/Bluetooth root@usbarmory:/home/usbarmory# microcom -p /dev/ttymxc0 AT+GMR "1.0.0-017" armoryctlno binary in package, requires 1.12 go (which isn't in debian buster as of now) Even worse, since device is on stretch it has go 1.7 which can't compile it. dpavlin@klin:~/usb-armory$ git clone https://github.com/inversepath/armoryctl dpavlin@klin:~/usb-armory/armoryctl$ make armoryctl GOARCH=arm github.com/inversepath/armoryctl/anna_b112 # github.com/inversepath/armoryctl/anna_b112 anna_b112/openocd.go:328:9: undefined: strings.ReplaceAll anna_b112/openocd.go:329:8: undefined: strings.ReplaceAll note: module requires Go 1.12make: *** [Makefile:27: armoryctl] Error 2 After compile:
