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. MAC addresses: LAN : 90:96:F3:xx:xx:30 (board_data, "mac" (text)) WAN : 90:96:F3:xx:xx:30 (board_data, "mac" (text)) 2.4 GHz: 90:96:F3:xx:xx:31 5 GHz : 90:96:F3:xx:xx:38 [original work] Signed-off-by: Audun-Marius Gangstø <audun@gangsto.org> [convert to ubi, fix/improve DT, add sysupgrade support] Signed-off-by: INAGAKI Hiroshi <musashino.open@gmail.com> |
