The Xunison Exigo Hub D50 5G is a 5G/LTE router with Wi-Fi 6. It is also
sold as the Zearts D50 5G.
Specifications:
SoC: Qualcomm IPQ5018, dual-core Cortex-A53 @ 1.0 GHz
RAM: 512 MiB
Flash: 128 MiB SPI NAND (ESMT F50D1G41LB)
WLAN: IPQ5018 2.4 GHz, QCN9074 5 GHz (PCIe), both 802.11ax
Ethernet: 1x GbE WAN (IPQ5018 internal GE PHY, gmac0)
3x GbE LAN (QCA8337 switch, SGMII to gmac1)
WWAN: Quectel RM500Q-AE, 5G Sub-6 / LTE Cat 16, on USB 2.0 and
PCIe
Buttons: reset, WPS
LEDs: MESH (green/red), 5G (green/red), 4G, WiFi, Internet, WAN;
power is hardwired
Power: 12 V / 2 A DC
Serial: 115200 8N1, 4-pin header JP1 next to SW4 on the main board,
from pin 1: VCC, TX, RX, GND
Notes:
- WAN is gmac0 wired straight to the internal GE PHY, not a switch
port; its netdev is named wan by the label property.
- The console RX line (gpio20) is pulled up. Left floating with nothing
on the header it causes an interrupt storm and, on some units, a hang
at boot.
- USB is 2.0 only: the controller is limited to the HS PHY and clocks
its pipe from UTMI. The 5 V supply for the port and the modem is
switched by gpio24 (active low).
- MACs follow the stock firmware: LAN uses 0:art 0x0, WAN 0:art 0x6.
The label has no MAC printed, so there is no label-mac-device.
- Wi-Fi calibration data and MAC addresses come from 0:art through
nvmem cells on the Wi-Fi nodes (calibration: IPQ5018 at 0x1000,
QCN9074 at 0x26800). The caldata holds the Qualcomm placeholder MAC,
so the radios take the 0:art 0x0 MAC + 2 and + 3 instead.
- Board data for both radios is submitted separately to
firmware_qca-wireless under the calibration variant
Xunison-Exigo-Hub-D50-5G, both taken from the stock firmware:
bdwlan.b24-brax for the IPQ5018 and qcn9000/bdwlan.ba0 for the
QCN9074. The brax file is the vendor's board variant; on my unit it
outperformed the bdwlan.b24 that the stock firmware loads.
- The modem power line (gpio31) has no consumer and is kept high with a
GPIO hog.
- The Internet LED is lit while the modem's wwan0 is up. The WiFi LED
uses the network trigger in link mode, so it is lit while an AP is up
on either radio; the phyNradio triggers never light it with ath11k on
this board. The 4G and 5G LEDs have no trigger, as nothing in the
kernel reports the modem's access technology.
Modem:
The RM500Q-AE is wired to both USB and PCIe, and its data_interface
setting selects which one carries data. The stock firmware leaves it on
PCIe (data_interface 1,0) and this port uses it there, so no AT command
is needed after installing. It is driven by mhi-pci-generic with MBIM:
data on wwan0, control on /dev/wwan0mbim0 and AT commands on
/dev/wwan0at0. No modem interface is preconfigured; add one with the
"mbim" protocol on /dev/wwan0mbim0.
Installation:
The factory image is a raw UBI image for the U-Boot web recovery.
1. Power the router off, hold the reset button and power it on. Keep
holding until the Internet LED stays lit (about 10 seconds).
2. Set a computer on a LAN port to 192.168.1.2/24 and open
http://192.168.1.254
3. Upload openwrt-qualcommax-ipq50xx-xunison_exigo-hub-d50-5g-squashfs-factory.img
and wait for the router to reboot.
Later upgrades use the sysupgrade image.
The port started from George Moussalem's device support in the 4IceG
OpenWrt tree, with the device tree reworked by Lukasz Szczur (LS3434):
USB, the modem supply and the NAND/sysupgrade layout. Thanks to Hostle
for the flashing work on this board and to Rafał Wabik (4IceG) for the
tree it was developed in.
