From bf81a921715c12fa8e177aad3893ec915a630c01 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Mon, 17 Apr 2023 19:15:22 +0200 Subject: ath79: create Aruba AP-105 APBoot compatible image Alter the Aruba AP-105 image generation process so OpenWrt can be loaded with the vendor Aruba APBoot. This works by prepending the OpenWrt LZMA loader to the uImage and jumping directly to the loader. Aruba does not offer bootm on these boards. This approach keeps compatibility to devices which had their U-Boot replaced. Both bootloaders can boot the same image. The same modification is most likely also possible for the Aruba AP-175. With this patch, new installations do not require replacing the bootloader and can be performed from the serial console without opening the case. Installation ------------ 1. Attach to the serial console of the AP-105. Interrupt autoboot and change the U-Boot env. $ setenv apb_rb_openwrt "setenv ipaddr 192.168.1.1; setenv serverip 192.168.1.66; netget 0x84000000 ap105.bin; go 0x84000040" $ setenv apb_fb_openwrt "cp.b 0xbf040000 0x84000000 0x10000; go 0x84000040" $ setenv bootcmd "run apb_fb_openwrt" $ saveenv 2. Load the OpenWrt initramfs image on the device using TFTP. Place the initramfs image as "ap105.bin" in the TFTP server root directory, connect it to the AP and make the server reachable at 192.168.1.66/24. $ run apb_rb_openwrt 3. Once OpenWrt booted, transfer the sysupgrade image to the device using scp and use sysupgrade to install the firmware.
