From 12f52336d2b18951d883af07f398fc9697adba24 Mon Sep 17 00:00:00 2001 From: Martin Kennedy Date: Sun, 18 Sep 2022 12:15:57 -0400 Subject: ath79: Add Aruba AP-175 support This board is very similar to the Aruba AP-105, but is outdoor-first. It is very similar to the MSR2000 (though certain MSR2000 models have a different PHY[^1]). A U-Boot replacement is required to install OpenWrt on these devices[^2]. Specifications -------------- * Device: Aruba AP-175 * SoC: Atheros AR7161 680 MHz MIPS * RAM: 128MB - 2x Mira P3S12D40ETP * Flash: 16MB MXIC MX25L12845EMI-10G (SPI-NOR) * WiFi: 2 x DNMA-H92 Atheros AR9220-AC1A 802.11abgn * ETH: IC+ IP1001 Gigabit + PoE PHY * LED: 2x int., plus 12 ext. on TCA6416 GPIO expander * Console: CP210X linking USB-A Port to CPU console @ 115200 * RTC: DS1374C, with internal battery * Temp: LM75 temperature sensor Factory installation: - Needs a u-boot replacement. The process is almost identical to that of the AP105, except that the case is easier to open, and that you need to compile u-boot from a slightly different branch: https://github.com/Hurricos/u-boot-ap105/tree/ap175 The instructions for performing an in-circuit reflash with an SPI-Flasher like a CH314A can be found on the OpenWrt Wiki (https://openwrt.org/toh/aruba/ap-105); in addition a detailed guide may be found on YouTube[^3]. - Once u-boot has been replaced, a USB-A-to-A cable may be used to connect your PC to the CP210X inside the AP at 115200 baud; at this point, the normal u-boot serial flashing procedure will work (set up networking; tftpboot and boot an OpenWrt initramfs; sysupgrade to OpenWrt proper.) - There is no built-in functionality to revert back to stock firmware, because the AP-175 has been declared by the vendor[^4] end-of-life as of 31 Jul 2020. If for some reason you wish to return to stock firmware, take a backup of the 16MiB flash before flashing u-boot.
