From d3c88811942a9dc9bbb01ca0443ae9cd790d1988 Mon Sep 17 00:00:00 2001 From: Stefan Schake Date: Fri, 2 Oct 2020 14:32:55 +0200 Subject: ipq40xx: add support for devolo Magic 2 WiFi next SOC: IPQ4018 / QCA Dakota CPU: Quad-Core ARMv7 Processor rev 5 (v71) Cortex-A7 DRAM: 256 MiB NOR: 32 MiB ETH: Qualcomm Atheros QCA8075 (2 ports) PLC: MaxLinear G.hn 88LX5152 WLAN1: Qualcomm Atheros QCA4018 2.4GHz 802.11bgn 2:2x2 WLAN2: Qualcomm Atheros QCA4018 5GHz 802.11a/n/ac 2:2x2 INPUT: RESET, WiFi, PLC Button LEDS: red/white home, white WiFi To modify a retail device to run OpenWRT firmware: 1) Setup a TFTP server on IP address 192.168.0.100 and copy the OpenWRT initramfs (initramfs-fit-uImage.itb) to the TFTP root as 'uploadfile'. 2) Power on the device while pressing the recessed reset button next to the Ethernet ports. This causes the bootloader to retrieve and start the initramfs. 3) Once the initramfs is booted, the device will come up with IP 192.168.1.1. You can then connect through SSH (allow some time for the first connection). 4) On the device shell, run 'fw_printenv' to show the U-boot environment. Backup this information since it contains device unique factory data. 5) Change the boot command to support booting OpenWRT: # fw_setenv bootcmd 'sf probe && sf read 0x84000000 0x180000 0x400000 && bootm' 6) Change directory to /tmp, download the sysupgrade (e.g. through wget) and install it with sysupgrade. The device will reboot into OpenWRT. Notice that there is currently no support for booting the G.hn chip. This requires userland software we lack the rights to share right now.
