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" armoryctlusbarmory@usbarmory:~$ sudo apt install armoryctl 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:
