They have 4x 1G LAN ports, a DSL/VDSL port up to 300Mb, and a USB 3.0 port. The FRITZ!Box 7520 is the same hardware platform as the 7530, but its OEM software reduces the speed of 2x LAN ports and the USB port. Those limits do not apply to OpenWRT.

Place it in the same directory as the eva_ramboot.py script. Assign yourself the IP address 192.168.178.10/24. Connect your Computer to one of the boxes LAN ports. Connect Power to the Box. As soon as the LAN port of your computer shows link, load the U-Boot to the box using following command. > ./eva_ramboot.py --offset 0x85000000 192.168.178.1 uboot-fritz7530.bin The U-Boot will now start. Now assign yourself the IP address 192.168.1.70/24. Copy the OpenWrt initramfs (!) image to a installed TFTP server root directory on our Computer and rename it to FRITZ7530.bin. The Box will now put the file (a pull request every 5 seconds) and boot OpenWrt into RAM. This can take up to two minutes. Copy the U-Boot and the OpenWrt sysupgrade (!) image to the Box using scp, like scp /tmp/uboot-fritz7530.bin root@192.168.1.1:/tmp/ scp /tmp/avm_fritzbox-7530-squashfs-sysupgrade.bin root@192.168.1.1:/tmp/ SSH into the Box and first write the Bootloader to both previous kernel partitions. mtd write /tmp/uboot-fritz7530.bin uboot0 mtd write /tmp/uboot-fritz7530.bin uboot1 Remove the AVM filesystem partitions to make room for our kernel + rootfs + overlayfs. ubirmvol /dev/ubi0 --name=avm_filesys_0 ubirmvol /dev/ubi0 --name=avm_filesys_1 Flash OpenWrt peristently using sysupgrade. sysupgrade -n /tmp/avm_fritzbox-7530-squashfs-sysupgrade.bin Flash Layout dev: size erasesize name mtd0: 00080000 00020000 "SBL1" mtd1: 00080000 00020000 "MIBIB" mtd2: 00080000 00020000 "QSEE" mtd3: 00040000 00020000 "CDT" mtd4: 00080000 00020000 "QSEE_B" mtd5: 00040000 00020000 "urlader0" mtd6: 00040000 00020000 "urlader1" mtd7: 00840000 00020000 "nand-tffs" mtd8: 00400000 00020000 "uboot0" mtd9: 00400000 00020000 "uboot1" mtd10: 06d00000 00020000 "ubi" OEM installation using the TFTP method See Installation Upgrading OpenWrt LuCI Web Upgrade Process Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL Upload image file for sysupgrade to LuCI Wait for reboot Terminal Upgrade Process sysupgrade Login as root via SSH on 192.168.1.1, then enter the following commands: cd /tmp wget https://downloads.openwrt.org/releases/21.02.0-rc2/targets/ipq40xx/generic/openwrt-21.02.0-rc2-ipq40xx-generic-avm_fritzbox-7530-squashfs-sysupgrade.bin sysupgrade /tmp/openwrt-21.02.0-rc2-ipq40xx-generic-avm_fritzbox-7530-squashfs-sysupgrade.bin WinScp If no Internet or WAN configured use WinScp''. and upload the file to /tmp 1st Login as root via WinScp on 192.168.1.1, then browse to /tmp and upload the openwrt-21.XX.XX-ipq40xx-generic-avm_fritzbox-7530-squashfs-sysupgrade.bin file 2nd Login as root via SSH on 192.168.1.1, then enter the following commands: cd /tmp sysupgrade /tmp/openwrt-21.02.0-rc2-ipq40xx-generic-avm_fritzbox-7530-squashfs-sysupgrade.bin Debricking For debrick and / or factory image recovery use the AVM Recovery Tool. Basic configuration Network interfaces The default network configuration as of 21.02.0-rc2 Interface Name Description Default configuration br-lan LAN & WiFi 192.168.1.1/24 eth0 Unknown port Unknown port eth1 LAN 1-4 LAN 1-4 wlan0 2.4GHz WiFi Disabled wlan1 5 GHz WiFi Disabled DSL Unsupported Unsupported VLAN Setup This device has one ethernet interface with 4 LAN ports. It does not have a fifth eth port for WAN like FB4040 eth0 is connected to the 4 LAN ports as well as the CPU. VLANs can be configured the standard OpenWrt way. The table below shows how they are displayed and numbered in LUCI. Switch Ports Port Switch port CPU (eth0) 0 LAN 1 1 LAN 2 2 LAN 3 3 LAN 4 4 A working VLAN setup is shown in the image below. This uses LAN 1 as a trunk port that receives tagged VLAN traffic from the network. LAN 2 and LAN 3 are members of VLAN 42 (used for the “Internal” network), LAN 4 is connected to VLAN 99 (used for a “Guest” network) When configuring the VLANs it is very important to bind the LUCI network interfaces to the correct physical interfaces before applying the settings. Otherwise you will be locked out of the device and need to reflash it! Go to LUCI→Network→Interfaces and check the “Physical Settings” for each one. Following the example above “Internal” would be connected to eth0.42 and “Guest” to eth0.99. When everything works as expected, corresponding WIFI networks can be added as a bridge here later on. It has been mentioned in the forums that with this SoC, VLAN IDs 1 and 2 are treated specially by the hardware driver (https://forum.openwrt.org/t/vlans-on-ipq40xx-alternative-config-for-fritzbox-4040/41832/6) so it is probably best to avoid VLAN ID 1 and 2 if possible. This may change with updated hardware drivers. Buttons → hardware.button on howto use and configure the hardware button(s). Here, we merely name the buttons, so we can use them in the above Howto.
