From 92fc0e6063e30ef7202c20e276a123bf8684214a Mon Sep 17 00:00:00 2001 From: Christian Lamparter Date: Wed, 23 Jun 2021 22:46:52 +0200 Subject: [PATCH] ath79: add Cisco Meraki Z1 Specifications: SOC: Atheros AR9344 @ 560MHz RAM: 2x Winbond W9751G6KB-25 (128 MiB) FLASH: Hynix H27U1G8F2BTR (128 MiB) WIFI1: Atheros AR9340 5.0GHz (SoC) WIFI2: Atheros AR9280 2.4GHz SWITCH: Atheros AR8236 (5x Gigabit (1x WAN, 4x LAN) LED: 1x Power-LED, 1 x RGB Tricolor-LED INPUT: One Reset Button USB: One USB 2.0 Port UART: JP1 on PCB (Labeled UART), 3.3v-Level, 115200n8 (GND, TX, RX, VCC - GND is next to the UART silk screen) Flashing Instructions: Since this device is brought over from an old AR71xx, there's already a wiki-page with detailed instructions: The gist: 1. Get a root-shell on the device (see wiki). (needs UART access) 2. make a backup (to a PC/safe location) of the existing Meraki firmware. 3. copy over the OpenWrt initramfs kernel for the Z1. This gets written into the kernel NAND partition. (Verify that written image is complete!) After the following reboot and successfull boot of the staging OpenWrt initramfs image: 4. copy over the sysupgrade.bin for the router and use sysupgrade to make the installation permanent.
