Plasma Cloud PAX1800-Lite is a dual-band Wi-Fi 6 router, based on MediaTek
MT7621A + MT79x5D platform.
Specifications:
- SOC: MT7621AT (880 MHz)
- DRAM: DDR3 448 MiB (Nanya NT5CC256M16DP-DI)
- Flash: 2 MiB SPI NOR (S25FL016K) + 128 MB SPI NAND (W25N02KVZEIR)
- Ethernet: 1x 10/100/1000 Mbps (SOC's built-in switch, with PoE+)
- Wi-Fi: 2x2:2 2.4/5 GHz (MT7905DAN + MT7975DN)
(MT7905DAN doesn't support background DFS scan/BT)
- LED: tri-color LED for status (red, blue, green)
- Buttons: 1x (reset)
- Antenna: 4x internal, non-detachable omnidirectional
- UART: 1x 4-pin (2.54 mm pitch, marked as "3V3 G/RX GND W/TX")
- Power: 12 V DC/2 A (DC jack)
MAC addresses:
WAN: 54:9C:27:xx:xx:00 (factory 0x3fff4, device label)
2.4 GHz: 54:9C:27:xx:xx:02 (factory 0x4, device label +2)
5 GHz: 54:9C:27:xx:xx:08 (factory 0xa, device label +8)
Flashing instructions:
======================
Various methods can be used to install the actual image on the flash.
Two easy ones are:
ap51-flash
----------
The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be
used to transfer the image to the u-boot when the device boots up.
initramfs from TFTP
-------------------
The serial console (115200 8N1) must be used to access the u-boot shell
during bootup. It can then be used to first boot up the initramfs image
from a TFTP server (here with the IP 192.168.1.21):
setenv serverip 192.168.1.21
setenv ipaddr 192.168.1.1
tftpboot 0x83001000 <filename-of-initramfs-kernel>.bin && bootm $fileaddr
The actual sysupgrade image can then be transferred (on the LAN port) to the
device via
scp <filename-of-squashfs-sysupgrade>.bin root@192.168.1.1:/tmp/
On the device, the sysupgrade must then be started using
sysupgrade -n /tmp/<filename-of-squashfs-sysupgrade>.bin
