ramips: add support for Plasma Cloud PAX1800-Lite 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 Signed-off-by: Sven Eckelmann (Plasma Cloud) Link: https://github.com/openwrt/openwrt/pull/20152 Signed-off-by: Hauke Mehrtens
