The firmware this smart plug (model number: F7C029de) runs doesn’t seem to be particularly stable and the software base seems very dated. Let’s try running our own firmware for fun and profit.

This article has been updated June 10, 2020 and June 21, 2020.

Hardware

The F7C029de smart plug contains three PCBs:

  1. The power board holds the relay, isolation and a power supply for the logic board.
  2. The power sensor board contains a chip similar (but not identical) to the 78M6610+PSU (datasheet) Energy Measurement Processor for Single-Phase Power-Supply Units and a few passive components. The board is soldered onto the power board.
  3. The logic board features a Ralink (Mediatek) RT5350F (datasheet) WiFi SoC with a 360 MHz MIPS24KEc CPU core and a IEEE 802.11n 1T1R peripheral. In addition, there is a MX25L12835F (datasheet) 16 MiB serial NOR flash and a W9825G6KH (datasheet) 32 MiB SDRAM as well as some LEDs, a tactile button, some voltage regulators and a USB micro AB receptacle.

J15 Connector pinout

  1. Relay signal (3.3V level output)
  2. GND
  3. 5V
  4. 5V
  5. GND
  6. ?
  7. UART from power sensor (3.3V level input)
  8. 3.3V

Pin 1 is marked with a little dot on the silk screen. It’s located on the right-hand side in the above photo of the board.

The logic board can be powered via the USB receptacle J11 (5V). The 3.3V rail is generated on the logic board.

Serial console

A serial console is available via test pads. It’s somewhat difficult to solder to the pads because they can be quite oxidized. I lifted a pad and decided to solder to the resistor pads instead. The voltage level is 3.3V and the default configuration is 57600 baud 8N1.

Bootloader

The board uses a modified u-boot version from the Ralink SDK v3.5.0.0. This is the u-boot console log:

The interactive shell can be entered by pressing and holding the 4 key while powering up the board. These are the available commands:

RT5350 # help
?       - alias for 'help'
bootm   - boot application image from memory
cp      - memory copy
erase   - erase SPI FLASH memory
flash_test - test flash status, argv => test_pattern_start test_pattern_end test_repeat
go      - start application at address 'addr'
help    - print online help
loadb   - load binary file over serial line (kermit mode)
md      - memory display
mdio   - Ralink PHY register R/W command !!
mm      - memory modify (auto-incrementing)
mw      - memory write (fill)
nm      - memory modify (constant address)
printenv- print environment variables
reset   - Perform RESET of the CPU
rf      - read/write rf register
saveenv - save environment variables to persistent storage
setenv  - set environment variables
tftpboot- boot image via network using TFTP protocol
version - print monitor version

The stock environment looks like this:

Environment size: 959/4092 bytes

The bootm command is modified and doesn’t behave like it does in upstream u-boot. It’s behaviour is dependent on the value of the bootstate environment variable. If bootstate=0, the bootm command behaves normally—at least if only one argument (the address) is passed to it.

Unfortunately, it doesn’t seem possible to change the baud rate to anything faster than 57600 baud. This means that serial downloads take a while.

Stock OS

This is the console log of the Linux OS after the settings had been restored to the factory defaults. After the device had been powered up, it was connected to a WiFi network.

The firmware version is WeMo_WW_2.00.10966.PVT-OWRT-Insight. There is a login prompt which doesn’t use a trivial password for the root user. I have been unable to crack the password using John The Ripper; here’s the salt and MD5 hash: $1$9CaSVCnb$y1c1i01eMl02W5pTmwehD1.

Partitions

The flash partition layout is as follows:

MX25L12805D(c2 2018c220) (16384 Kbytes)
mtd .name = raspi, .size = 0x01000000 (16M) .erasesize = 0x00010000 (64K) .numeraseregions = 0
Creating 12 MTD partitions on "raspi":
0x00000000-0x00050000 : "uboot"
0x00050000-0x00190000 : "Kernel_1"
0x00190000-0x007c0000 : "rootfs_1"
0x007c0000-0x00900000 : "Kernel_2"
0x00900000-0x00f30000 : "rootfs_2"
mtd: partition "rootfs_2" set to be root filesystem
mtd: partition "rootfs_data" created automatically, ofs=C90000, len=2A0000 
0x00c90000-0x00f30000 : "rootfs_data"
0x00fe0000-0x00ff0000 : "nvram"
0x00ff0000-0x01000000 : "User_Factory"
0x00040000-0x00050000 : "Factory"
0x00f30000-0x00fd0000 : "Belkin_settings"
0x00030000-0x00040000 : "Uboot_env"
0x00050000-0x007c0000 : "Firmware_1"
0x007c0000-0x00f30000 : "Firmware_2"

We know furthermore, that the root filesystem is a SquashFS 3.0 with a JFFS2 mini_fo overlay. There are two kernel partitions and two root filesystem partitions. This is used for firmware updates where the new firmware is written to the inactive partition set. The Factory partition seems to hold calibration data for the WiFi peripheral. Belkin_settings is a JFFS2 partition with some application data. nvram is a key-value store for configuration parameters. uboot and Uboot_env holds the u-boot program and its environment, respectively. User_Factory appears to hold static manufacturing data like serial number, region, country, model and MAC address.

Booting your own Kernel

I’m not sure whether it’s possible to specify kernel command line and device tree from u-boot, so the safest bet is to use a kernel with baked in command line and appended device tree. This type of image is built by default when building RT5350 images with OpenWrt. My initial plan was to mount one of the existing root filesystem partitions when booting the custom kernel. However, the device uses SquashFS 3.0 which is incompatible with the current version 4.0. In order to have a functional root filesystem, we boot an image with initial RAM disk. This type of image is also built automatically by OpenWrt. The OpenWrt target f7c027 is close enough to this hardware that it boots the kernel without problems. However, I have also created a f7c029 target which has the correct LED and button GPIO mapping.

In order to boot a custom image, run the following in an interactive u-boot shell:

setenv bootstate 0; loadb 0x80600000
# Send openwrt-ramips-rt305x-f7c029-initramfs-kernel.bin via kermit
bootm 0x80600000

This will take some time but it will get you a Linux shell. Depending on which packages you built, you can read and transfer (gkermit) the stock partitions. You will also be able to transfer the an image permanently to flash which allows you to boot much faster afterwards. I have written kernel and root filesystem to the inactive partitions, i.e. the one that doesn’t hold the currently active stock image. This target partition should be labelled firmware in the device tree while the other one should be called firmware2.

cd /tmp
gkermit -r
# Send openwrt-ramips-rt305x-f7c029-squashfs-sysupgrade.bin via kermit
sysupgrade -n /tmp/openwrt-ramips-rt305x-f7c029-squashfs-sysupgrade.bin

It makes sense to increase the serial baud rate to 230400 before these transfers in order to save some time:

stty -F /dev/ttyS0 230400

After a reboot, you’ll be able to boot your kernel and root filesystem by running the following in the u-boot shell (note, that these values depend on whether you write your stuff to Firmware_1 or Firmware_2:

setenv bootstate 0
bootm 0xBC050000

In order to make it permanent, run:

setenv bootstate 0
setenv bootpart 0
setenv check_boot 0
saveenv
reset

Excursion: kermit with minicom on Arch Linux

There seems to be a problem with some lock files that ckermit tries to write in Arch Linux. In order to fix this, modify your ~/.minirc.dfl to contain the following lines:

pu pname7           YUYNNkermit
pu pname8           NDYNNkermit
pu pprog7           /usr/bin/env LOCK_DIR=/tmp /usr/bin/ckermit -i -l %l -b %b -s
pu pprog8           /usr/bin/env LOCK_DIR=/tmp /usr/bin/ckermit -i -l %l -b %b -r

Additionally, I have found the following ~/.kermrc to work:

set carrier-watch off
set handshake none
set flow-control none
robust
set file type bin
set rec pack 1000

Controlling the relay

In order to control the relay via HTTP, add the following small CGI script to /www/cgi-bin/relay and make it executable:

#!/bin/sh

relay_file="/sys/class/leds/f7c029:device:relay/brightness"

bad_request() {
	echo "Status: 400 Bad Request"
	echo
	exit 1
}

set_state() {
	echo "$1" > "$relay_file"
	echo "$1" > "/sys/class/leds/f7c029:green:power/brightness"
}

if [ "$REQUEST_METHOD" == "GET" ]; then
	echo
	sed -e s/0/off/ -e s/1/on/ "$relay_file"
elif [ "$REQUEST_METHOD" == "POST" ]; then
	cmd="$(cat)"
	case "$cmd" in
	on)
		set_state 1
		;;
	off)
		set_state 0
		;;
	*)
		bad_request
		;;
	esac	

	echo
	echo "$cmd"
else
	bad_request
fi

Now the relay can be controlled e.g. via cURL:

curl -d {on,off} OpenWrt.local/cgi-bin/relay

Manual control via the touch button

Adding the following executable script to /etc/rc.button/BTN_1 allows to control the relay using the touch field:

#!/bin/sh

relay_file="/sys/class/leds/f7c029:device:relay/brightness"

set_state() {
	echo "$1" > "$relay_file"
	echo "$1" > "/sys/class/leds/f7c029:green:power/brightness"
}

if [ "$ACTION" != "pressed" ]; then
	exit
fi

case "$(cat "$relay_file")" in
0)
	set_state 1
	;;
1)
	set_state 0
	;;
esac

Issues

  • The RT5350 gets noticeably hotter (60°C vs. 50°C with stock firmware) with the new kernel. Update: This issue has at least been partially solved.
  • The WiFi throughput seems very low at ~160 kB/s. This shouldn’t be a big problem for this type of device.

Remaining work

  • Interface the power sensor
  • Crack the stock firmware password
