Hi-Link HLK-RM04

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.
DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details.

1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.
This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.

2) OpenWrt support for this device has ended in 2022.
19.07.10 was the last official build for 4/32 devices.

This is not a router product, but a router module designed by Hi-Link. HLK-RM04 is a low-cost embedded UART-ETH-WIFI module (serial port - Ethernet - Wireless network). This product is an embedded module based on the universal serial interface network standard, built-in TCP / IP protocol stack, enabling the user serial port, Ethernet, wireless network (wifi) interface between the conversions. Through the HLK-RM04 module, the traditional serial devices do not need to change any configuration; data can be transmitted through the Internet network. Provide a quick solution for the user’s serial devices to transfer data via Ethernet.

Compile

Get patch on github, follow the guide to compile Openwrt.

or use guide below which works better on later OpenWRT versions (tested on 18.06.xx)

Build your own OpenWRT image for Hi-link hlk-rm04 modules with 8MB flash and 32 MB RAM

Installation

So far, WEBUI upgrade firmware does not work for flash openwrt image. This installtion need two steps:

  • replace the HiLink official uboot
  • use the new uboot to flash Openwrt image

Prepare

  • USB2Serial or USB2TTL tool
  • One Network cable
  • serial concole(putty or similar)
  • tftp server, (Ubuntu tftp-hpa; Windows: Tftpd32.exe)

Step by Step

Replace the uboot

  1. set your PC ipadress to 192.168.16.100, Gateway 192.168.16.254, may be difference if you have changed it once.
  2. connect HLK-RM04 LAN port to your PC, power up HLK-RM04
  3. access http://192.168.16.254/adm/hlk_update_www_hlktech_com.asp (user: admin, password: admin if required), replace 192.168.16.254 with yours, if you've changed it once.
  4. find Update Bootloader option, click Choose File, then select uboot128.img or for 8MB flash and 32MB RAM modules use uboot256.img, click Apply then click OK to make sure.

Here, we have replaced the uboot of HLK-RM04 successfully. And now the hlk-rm04 works fine, only thing what we change is let Uboot 'talk' to us, so that we can use uboot to download the openwrt image.

Flash Openwrt with new Uboot

  1. configure a tftp server.
    • For Ubuntu, See more Install tftp info
      • sudo apt-get install tftpd-hpa 
sudo service tftpd-hpa start
cp bin/ramips/openwrt-ramips-rt305x-hlk-rm04-squashfs-sysupgrade.bin /var/lib/tftpboot/
    • An alternative method to tftpd-hpa is dnsmasq:
      • Install dnsmasq, for ex under ubuntu/debian:
        apt-get install dnsmasq
      • Create a directory where you will put the TFTP files:
        mkdir -p /var/lib/tftpboot
      • Copy the firmware upgrade file:
        cp openwrt-ramips-rt305x-hlk-rm04-squashfs-sysupgrade.bin /var/lib/tftpboot/
      • Create an /etc/dnsmasq.conf with 2 lines: 
        enable-tftp
tftp-root=/var/lib/tftpboot
      • Launch dnsmasq in debug mode: 
        $ dnsmasq -d
dnsmasq: started, version 2.71 cachesize 150
dnsmasq: compile time options: IPv6 GNU-getopt no-DBus i18n IDN DHCP DHCPv6 no-Lua TFTP conntrack ipset no-auth no-DNSSEC
dnsmasq-tftp: TFTP root is /var/lib/tftpboot 
dnsmasq: reading /etc/resolv.conf
dnsmasq: using nameserver 8.8.8.8#53
dnsmasq: read /etc/hosts - 8 addresses
    • For Windows, download Tftpd32.exe, place `openwrt-ramips-rt305x-hlk-rm04-squashfs-sysupgrade.bin' in the same directory with Tftpd32.exe, choose a right server ip.
  2. open serial use 57600,8,n,1, make sure you have connect the serial cable.
  3. Restart your HLK-RM04 module. Push '2' rapidly to enter the tftp write flash mode.
  4. Set device ip 192.168.16.1, Set server ip 192.168.16.100.
  5. input the file name openwrt-ramips-rt305x-hlk-rm04-squashfs-sysupgrade.bin
    • 2: System Load Linux Kernel then write to Flash via TFTP.
Warning!! Erase Linux in Flash then burn new one. Are you sure?(Y/N)
Please Input new ones /or Ctrl-C to discard
    Input device IP (10.10.10.123) ==:192.168.16.1
    Input server IP (10.10.10.3) ==:192.168.16.100
    Input Linux Kernel filename (tim_uImage) ==:openwrt-ramips-rt305x-hlk-rm04-squashfs-sysupgrade.bin

Wait flashing finished, then you can use Openwrt on HLK-RM04.

Outdated approach

There is not a simple way to run OpenWrt on this tiny module, because Hi-link disabled uboot. Therefor we can solve this by finding a Hi-Link compatible firmware for it.

For example of *Hame MPR-A1*:

  • Solder out the Hame MPR-A1's 4M flash, then just copy all 4M content.
  • Solder out the Hi-Link's 4M flash, write the MPR-A1's 4M firmware to it.
  • Solder back the flash, Now the Hi-Link HLK-RM04 performs like a MPR-A1, and more information here.

hlk-rm04-mem-config

By default, memory configuration of hlk-rm04 select 32M/32M*2, but it uses 16M SDRAM, so if you don't want to modify hardware, you must manually specify the memory size for openwrt. If you want openwrt to check the SDRAM size automatically, then you need to solder out R144 and solder back it to R146 and make R24 to R25. R144 and R146 are on the front side, R24 and R25 are on the back side.

If you want to expand the SDRAM to 32M, just exchange the SDRAM chip, and don't change the resister, because it select 32M SDRAM by default.

In fact R144/R146 are pull up/down resisters for pin EPHY_LED3_N, R24/R25 are pull up/down resisters for EPHY_LED2_N. 

R144	pull up resister for EPHY_LED3_N
R146	pull down resister for EPHY_LED3_N
R24	pull up resister for EPHY_LED2_N
R25	pull down resister for EPHY_LED2_N

Upgrade to 32M compatible SDRAM

You will need SDRAM that conforms to 4 Meg x 16 x 4 banks in a 54 pin TSOP II package

Original firmware

The U-Boot shell appears to be disabled by the OEM.

Holding down the WPS button during power-on forces TFTP loading. Depending on the duration of the time you held the WPS button, one of two TFTP modes run. At least one of these modes will write to flash. Please error on the side of caution, you can brick your device. Be prepared to desolder your SPI flash if you play here.

There are at least 3 ways to break into the stock firmware:

UART2 login

Hi-Link left a modified version of getty running on ttyS0, configured for 57600 8n1, which waits for the sequence “174317529705122” followed by a carriage return. After that, it will begin passsing characters to/from the login program. The “login:” prompt should already been issued and should be waiting for a username. You will not see the “login:” prompt unless you have a failed login attempt.

AT command

There is an undocumented “at+excxxx” command you can use in configuration mode. Command output is discarded; however you can redirect output to /dev/ttyS1 to see it.

Examples: 

at+excxxx=telnetd
at+excxxx=ls / > /dev/ttyS1

HTTP post

There is this: 

http://192.168.16.254/adm/hlk_1037283194.asp

However, commands are sent to the wrong URL. This Github Gist is the solution to that problem:

Commands only work when sent via HTTP POST. GET requests do not work.

Default login user: admin
Default password: admin

Boot Log

Default firmware output disabled by Hi-Link. No boot log.

Currently defined functions: [, [[, ash, basename, brctl, cat, chmod, chpasswd, cp, date, echo, expr, free, getty, grep, halt, hostname, ifconfig, init, init, insmod, kill, killall, klogd, logger, login, logread, ls, lsmod, mdev, mkdir, mknod, mount, ping, ping6, poweroff, printf, ps, pwd, reboot, rm, rmmod, route, sed, sh, sleep, syslogd, telnetd, test, tftp, top, touch, udhcpc, udhcpd, umount, uptime, vconfig, wc # ifconfig br0 Link encap:Ethernet HWaddr 44:33:4C:A4:05:02 inet addr:192.168.16.254 Bcast:192.168.16.255 Mask:255.255.255.0 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:4165 errors:0 dropped:0 overruns:0 frame:0 TX packets:3279 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:4947945 (4.7 MiB) TX bytes:535173 (522.6 KiB) eth2 Link encap:Ethernet HWaddr 44:33:4C:A4:05:02 UP BROADCAST RUNNING PROMISC MULTICAST MTU:1500 Metric:1 RX packets:4170 errors:0 dropped:0 overruns:0 frame:0 TX packets:3465 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:1000 RX bytes:5023682 (4.7 MiB) TX bytes:658881 (643.4 KiB) Interrupt:3 eth2.1 Link encap:Ethernet HWaddr 44:33:4C:A4:05:02 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:4170 errors:0 dropped:0 overruns:0 frame:0 TX packets:3279 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:4965302 (4.7 MiB) TX bytes:548289 (535.4 KiB) eth2.2 Link encap:Ethernet HWaddr 44:33:4C:A4:05:03 UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:186 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:110484 (107.8 KiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:14 errors:0 dropped:0 overruns:0 frame:0 TX packets:14 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:2255 (2.2 KiB) TX bytes:2255 (2.2 KiB) # [TAB][TAB] [ config-pppoe.sh hostname ls printf telnetd [[ config-pptp.sh ifconfig lsmod ps test accel-pptp.sh config-udhcpd.sh igmpproxy mdev pwd tftp ash config-vlan.sh igmpproxy.sh mii_mgr ralink_init top ated config.sh inadyn mkdir readme touch autoconn3G.sh cp init mknod reboot udhcpc automount.sh cpubusy.sh insmod mount reg udhcpc.sh basename date internet.sh mtd_write rm udhcpd brctl ddns.sh iptables nat.sh rmmod umount busybox dnsmasq ipv6_logo.sh ntp.sh route upnp_xml.sh cat echo iwconfig ntpclient rt2860apd upnpd chmod expr iwpriv nvram_daemon rtinicapd uptime chpasswd firewall.sh kill nvram_get sed vconfig chpasswd.sh free killall nvram_set ser2net vpn-passthru.sh config-dns.sh getty klogd ping sh wan.sh config-dslite.sh global.sh lan.sh ping6 sleep wc config-iTunes.sh goahead lld2d poweroff snmp.sh wifi_unload.sh config-igmpproxy.sh gpio logger pppd snort.sh wscd config-l2tp.sh grep login pppoe-relay switch config-powersave.sh halt logread pppoe.sh syslogd # free total used free shared buffers Mem: 13788 12744 1044 0 880 Swap: 0 0 0 Total: 13788 12744 1044
