From 5fc28ef47959c1256f2553d507224bb481b08494 Mon Sep 17 00:00:00 2001 From: Sven Eckelmann Date: Mon, 23 Nov 2020 13:41:34 +0100 Subject: ath79: Add support for Plasma Cloud PA300 Device specifications: * Qualcomm/Atheros QCA9533 v2 * 650/600/217 MHz (CPU/DDR/AHB) * 64 MB of RAM * 16 MB of SPI NOR flash (mx25l12805d) - 2x 7 MB available; but one of the 7 MB regions is the recovery image * 2x 10/100 Mbps Ethernet * 2T2R 2.4 GHz Wi-Fi * multi-color LED (controlled via red/green/blue GPIOs) * 1x GPIO-button (reset) * external h/w watchdog (enabled by default) * TTL pins are on board (arrow points to VCC, then follows: GND, TX, RX) * 2x fast ethernet - eth0 + Label: Ethernet 1 + 24V passive POE (mode B) + used as WAN interface - eth1 + Label: Ethernet 2 + 802.3af POE + builtin switch port 2 + used as LAN interface * 12-24V 1A DC * internal antennas Flashing instructions: The tool ap51-flash (https://github.com/ap51-flash/ap51-flash) should be used to transfer the factory image to the u-boot when the device boots up.
