Installation (Safe)

[!CAUTION] This is a FIXED version of the instructions from the original commit message. The final rewrite of the default bootcmd variable was missing there.

Download the OpenWrt initramfs-image. Place it into a TFTP server root directory and rename it to 1401A8C0.img. Configure the TFTP server to listen at 192.168.1.66/24.
Connect the TFTP server to the access point.
Connect to the serial console of the access point. Attach power and interrupt the boot procedure when prompted (bootdelay is 1 second).

Configure the U-Boot environment for booting OpenWrt from Ram and flash:

setenv boot_openwrt 'setenv bootargs; bootm 0xbf080000'

setenv ramboot_openwrt 'setenv serverip 192.168.1.66; tftpboot; bootm'

saveenv

Load OpenWrt into memory:
```
run ramboot_openwrt
```
Wait for the image to boot.
Transfer the OpenWrt sysupgrade image to the device. Write the image to flash using sysupgrade:
```
sysupgrade -n /path/to/openwrt-sysuograde.bin
```

Installation without initramfs detour

You can install Gluon or OpenWrt also without detouring the initramfs. The initramfs method is described in the original PR, as it is a bit safer to human error as the following method.

However, the following method is quicker for bulk installation.

1. Download and Prepare image

Put the sysupgrade image at a tftp server at 192.168.1.66/24.

Name the file ap3610-sysupgrade.bin.

2. Prepare Access-Point

Execute the following command on the U-Boot shell.

setenv boot_openwrt 'setenv bootargs; bootm 0xbf080000'; setenv bootcmd 'run boot_openwrt'

setenv ramboot_openwrt 'setenv serverip 192.168.1.66; tftpboot; bootm';

setenv flashwrite_openwrt 'setenv serverip 192.168.1.66; tftpboot 0x84000000 ap3610-sysupgrade.bin; erase 0xbf080000 +0xe00000; cp.b 0x84000000 0xbf080000 0xe00000'; saveenv

3. Flash OpenWrt / Gluon

run flashwrite_openwrt

This results in:

You can now reboot the AP either by power-cycling or entering reset on the U-Boot CLI.

Autoinstallation

A Script for bulk.installation of the APs with initramfs method exists.
