NEC Aterm WG1800HP2 is a 2.4/5 GHz band 11ac (Wi-Fi 5) router, based on
QCA9558.
Specification:
- SoC : Qualcomm Atheros QCA9558
- RAM : DDR2 128 MiB (2x Nanya NT5TU32M16DG-AC)
- Flash : SPI-NOR 16 MiB (Macronix MX25L12845EMI-10G)
- WLAN : 2.4/5 GHz
- 2.4 GHz : 3T3R (Qualcomm Atheros QCA9558 (SoC))
- 5 GHz : 3T3R (Qualcomm Atheros QCA9880)
- Ethernet : 5x 10/100/1000 Mbps
- switch : Atheros AR8327
- LEDs/Keys (GPIO) : 12x/5x
- UART : through-hole on PCB
- assignment : 3.3V, GND, NC, TX, RX from tri-angle marking
- settings : 9600n8
- USB : 1x USB 2.0 Type-A
- hub (internal) : NEC uPD720114
- Power : 12 VDC, 1.5 A (Max. 17 W)
- Stock OS : NetBSD based
Flash instruction using initramfs-factory.bin image (StockFW WebUI):
1. Boot WG1800HP2 with router mode normally
2. Access to the WebUI ("http://aterm.me/" or "http://192.168.0.1/") on
the device and open firmware update page ("ファームウェア更新")
3. Select the OpenWrt initramfs-factory.bin image and click update
("更新") button
4. After updating, the device will be rebooted and booted with OpenWrt
initramfs image
5. On the initramfs image, upload (or download) uboot.bin and
sysupgrade.bin image to the device
6. Replace the bootloader with a uboot.bin image
mtd write <uboot.bin image> bootloader
7. Perform sysupgrade with a sysupgrade.bin image
sysupgrade <sysupgrade image>
8. Wait ~120 seconds to complete flashing
Flash instruction using initramfs-factory.bin image (bootloader CLI):
1. Connect and open serial console
2. Power on WG1800HP2 and interrupt bootloader by ESC key
3. Login to the bootloader CLI with a password "chiron"
4. Start TFTP server by "tftpd" command
5. Upload initramfs-factory.bin via tftp from your computer
example (Windows): tftp -i 192.168.0.1 PUT initramfs-factory.bin
6. Boot initramfs image by "boot" command
7. On the initramfs image, back up the stock bootloader and firmware if
needed
8. Upload (or download) uboot.bin and sysupgrade.bin image to the device
9. Replace the bootloader with a uboot.bin image
10. Perform sysupgrade with a sysupgrade.bin image
11. Wait ~120 seconds to complete flashing
Notes:
- All LEDs are connected to the TI TCA6416A (marking: PH416A) I2C
Expander chip.
- The stock bootloader requires an unknown filesystem on firmware area
in the flash. Booting of OpenWrt from that filesystem cannot be
handled, so the bootloader needs to be replaced to mainline U-Boot
before OpenWrt installation.

Enable access to uboot menu (needed in wvrtm-130acn):
- The access to uboot menu is blocked by `bootdelay = 0` set in ubootenv.
With stock firmware version 01.01.02.163 and previous, you can use CVE 2020-24365
command injection https://nvd.nist.gov/vuln/detail/CVE-2020-24365
python3 exploit.py -t 192.168.1.1 -c "fw_setenv bootdelay 3; fw_saveenv"
Backup the stock firmware:
- Connect via uart
- Connect via ethernet and assign your pc the address 192.168.15.x/24
- Power on the device; and start typing '4' to enter uboot menu
- Set factory mode and boot
MT7621 # setenv factory 2; saveenv
MT7621 # nand read 2800000 2000000 81000000; bootm
- Telnet and copy all mtd blocks
telnet 192.168.15.1
- Copy all mtd blocks and start webserver
for N in $(seq 0 6); do dd if=/dev/mtd$N of=/tmp/eeprom_mtd$N.bin; done
mount -o bind /tmp /www
lighttpd -f /etc/lighttpd.conf
- Backup stock rootfs_data (optional)
dd if=/dev/mtd7 of=/tmp/eeprom_mtd7.bin
dd if=/dev/mtd8 of=/tmp/eeprom_mtd8.bin
- Download to your pc from http://192.168.15.1/eeprom_mtd$N.bin
Installation:
- Connect via uart
- Connect via ethernet and assign your pc the address 10.10.10.3/24
- Start a tftp server and serve the image initramfs-kernel.bin
mkdir /tmp/ftpd;
cp initramfs-kernel.bin /tmp/ftpd/kernel.bin
dnsmasq --enable-tftp --tftp-root=/tmp/ftpd
- Power on the device; and start typing '4' to halt the bootloader
- Change the active mtd partition from mtd6 to mtd5 (needed by uboot)
MT7621 # setenv mtddevnum 5; saveenv
- Write the openwrt initramfs in ram via tftp and boot it
MT7621 # tftpboot 81000000 kernel.bin; bootm
- From the initramfs create the ubi device and install openwrt via sysupgrade
ubiformat /dev/mtd11 -y
sysupgrade -n -v /tmp/sysupgrade.bin
Recovery:
Restore the stock firmware from the backup of the mtd blocks
mtd write eeprom_mtd5.bin firmware
mtd write eeprom_mtd6.bin Kernel2
mtd write eeprom_mtd7.bin Storage1
mtd write eeprom_mtd8.bin Storage2

The swconfig-based b53 driver for the BCM53128 switch stopped working
after commits b2cfed48f6 (Revert "swconfig: fix Broadcom b53 support")
and e4e410733f (kernel: export switch_generic_set_link() symbol). This
rendered the 8 LAN ports of the EdgeSwitch 8XP non-functional, so the
image compilation for the device was disabled (5a1d7d8c1b).
This commit adds the kmod-dsa-b53-mdio and kmod-dsa-b53 packages
with the upstream B53 DSA driver, replacing the swconfig-based
kmod and kmod-switch-bcm53xx-mdio downstream ones that are not used by
any other device.
The 8 LAN ports of the EdgeSwitch 8XP are usable again. The 02_network
init script has been updated with the new DSA interfaces lan1 .. lan8.
Image building has been reenabled for the device, adding the usual DSA
incompatibility notice.
Tested on a Ubiquiti EdgeSwitch 8XP.

In #16396, crashes were reported on MT7620, which were introduced by enabling
CONFIG_LIST_HARDENED. The cause seems to be random memory corruption somewhere
in the kernel. Unfortunately the crash traces do not point to the real cause
of the crash in any way.
Since MT7620 is really ancient hardware that likely only has few users left,
I don't expect that anybody will invest a significant amount of time to track
down the real cause. Because of that, let's disable CONFIG_LIST_HARDENED on
this target only, and leave it enabled on all other platforms.
