Buffalo WSR-2533DHPLS is a 2.4/5 GHz band 11ac router, based on MediaTek
MT7621A.
Very similar to Buffalo WSR-2533DHPL, but with NAND, different GPIO
and TRX partitions.
Specification:
- SoC : MediaTek MT7621AT
- RAM : DDR3 256 MiB (Samsung K4B2G1646F-BYMA)
- Flash : RAW-NAND 128 MiB
(Winbond W29N01HV or KIOXIA TC58BVG0S3HTAI0)
- WLAN : 2.4/5 GHz (2x MediaTek MT7615N)
- Ethernet : 10/100/1000 Mbps
- Switch : MediaTek MT7530 (SoC) 4 ports
- LED/keys : 8x/6x (2x buttons, 1x slide-switch)
- UART : through-hole on PCB (J4)
- arrangement : 3.3V, GND, TX, RX from triangle-mark
- settings : 115200n8
- Power : 12VDC 1.5A
Flash instruction using factory.bin image:
1. boot WSR-2533DHPLS 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-2533DHPLS
3. after 10 seconds, release the "AOSS" button, WSR-2533DHPLS 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:
- The embedded addresses in eeprom data in Factory partition have
Buffalo's OUI, but they don't match with the actual addresses
assigned to wlan devices. So fixup addresses by the user-space
script.
root@localhost:/# hexdump -C /dev/mtdblock3 | grep "^0000[08]000\s"
00000000 15 76 a0 00 88 57 ee bc 01 a8 15 76 c3 14 00 80 |.v...W.....v....|
00008000 15 76 a0 00 88 57 ee bc 01 f8 15 76 c3 14 00 80 |.v...W.....v....|
See "MAC addresses" below for actual addresses.
- 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.
