Flash instruction using factory.bin image:
1. boot WSR-2533DHPL2 normally with "Router" mode
2. access to the WebI ("http://192.168.11.1/") on the device and open
firmware update page
("管理" -> "ファームウェア更新")
3. select the OpenWrt factory.bin image and click update ("更新実行")
button
Attention: do not use "factory-uboot.bin" image
4. Wait ~120 seconds to complete flashing
Flash instruction using initramfs image:
1. prepare the TFTP server with the initramfs image renamed to
"linux.trx-recovery" and IP address "192.168.11.2"
2. press the "AOSS" button while powering on the WSR-2533DHPL2
3. after 10 seconds, release the "AOSS" button, WSR-2533DHPL2 downloads
the initramfs image and boot with it automatically
4. on the initramfs image, download the factory-uboot.bin image to the
device and perform sysupgrade with it and "-F" option
5. wait ~120 seconds to complete flashing
Notes:
- There are 2x factory*.bin images for different purposes.
- factory.bin : for flashing on OEM WebUI
- factory-uboot.bin: for flashing on OEM bootloader or initramfs image
factory-uboot.bin is useful for recoverying the device, or refreshing
when the kernel partition is expanded in the future. sysupgrade on
this device accepts factory-uboot.bin with option "-F", but on that
situation, user configurations won't be kept, so it's not for normal
use.
