I can't find anywhere the OEM firmware. So if you want to restore the original firmware you must do a dump before the OpenWrt flash. According to the U-Boot, the board name is Iyunlink MINI_V2. Hardware -------- SoC: Qualcomm QCA9533 650/400/200/25/25 MHz (CPU/RAM/AHB/SPI/REF) RAM: 128 MB DDR2 16-bit CL3-4-4-10 (Nanya NT5TU64M16HG-AC) FLASH: 16 MB Winbond W25Q128 ETH: - 2x 100M LAN (QCA9533 internal AR8229 switch, eth0) - 1x 100M WAN (QCA9533 internal PHY, eth1) WIFI: - 2.4GHz: 1x QCA9533 2T2R (b/g/n) - 2 external non detachable antennas (near the power barrel side) LTE: - Quectel EC200T-EU (or -CN or -AU depending on markets) - 2 external non detachable antennas (near the sim slot side) BTN: - 1x Reset button LEDS: - 5x White leds (Power, Wifi, Wan, Lan1, Lan2) - 1x RGB led (Internet) UART: 115200-8-N-1 (Starting from lan ports in order: GND, RX, TX, VCC) Everything works correctly. MAC Addresses ------------- LAN XX:XX:XX:XX:XX:48 (art@0x1002) WAN XX:XX:XX:XX:XX:49 (art@0x1002 + 1) WIFI XX:XX:XX:XX:XX:48 LABEL XX:XX:XX:XX:XX:48 Installation ------------ Turn the router on while pressing the reset button for 4 seconds. You can simply count the flashes of the first lan led. (See notes) If done correctly you should see the first lan led glowing slowly and you should be able to enter the U-Boot web interface. Click on the second tab ("固件") and select the -factory.bin firmware then click "Update firmware". A screen "Update in progress" should appear. After few minutes the flash should be completed. This procedure can be used also to recover the router in case of soft brick. Backup the original firmware ---------------------------- The following steps are intended for a linux pc. However using the right software this guide should also work for Windows and MacOS. 1) Install a tftp server on your pc. For example tftpd-hpa. 2) Create two empty files in your tftp folder called: kuwfi_c910_all_nor.bin kuwfi_c910_firmware_only.bin 3) Give global write permissions to these files: chmod 666 kuwfi_c910_all_nor.bin chmod 666 kuwfi_c910_firmware_only.bin 4) Start a netcat session on your pc with this command: nc -u -p 6666 192.168.1.1 6666 5) Set the static address on your pc: 192.168.1.2. Connect the router to your pc. 6) Turn the router on while pressing the reset button for 8-9 seconds. You can simply count the flashes of the first lan led. If you press the reset button for too many seconds it will continue the normal boot, so you have to restart the router. (See notes) 7) If done correctly you should see the U-Boot network console and you should see the following lines on the netcat session: Version and build date: U-Boot 1.1.4-55f1bca8-dirty, 2020-05-07 Modification by: Piotr Dymacz https://github.com/pepe2k/u-boot_mod u-boot> 8) Start the transfer of the whole NOR: tftpput 0x9f000000 0x1000000 kuwfi_c910_all_nor.bin 9) The router should start the transfer and it should end with a message like this (pay attention to the bytes transferred): TFTP transfer complete! Bytes transferred: 16777216 (0x1000000) 10) Repeat the same transfer for the firmware: tftpput 0x9f050000 0xfa0000 kuwfi_c910_firmware_only.bin 11) The router should start the transfer and it should end with a message like this (pay attention to the bytes transferred): TFTP transfer complete! Bytes transferred: 16384000 (0xfa0000) 12) Now you have the backup for the whole nor and for the firmware partition. If you want to restore the OEM firmware from OpenWrt you have to flash the kuwfi_c910_firmware_only.bin from the U-Boot web interface. WARNING: Don't use the kuwfi_c910_all_nor.bin file. This file is only useful if you manage to hard brick the router or you damage the art partition (ask on the forum) Notes ----- This router (or at least my unit) has the pepe2k's U-Boot. It's a modded U-Boot version with a lot of cool features. You can read more here: https://github.com/pepe2k/u-boot_mod With this version of U-Boot, pushing the reset button while turning on the router starts different tools: - 3-5 seconds: U-Boot web interface that can be used to replace the firmware, the art or the U-Boot itself - 5-7 seconds: U-Boot uart console - 7-10 seconds: U-Boot network console - 11+ seconds: Normal boot The LTE modem can be used in cdc_ether (ECM) or RNDIS mode. The default mode is ECM and in this commit only the ECM software is included. In order to set RNDIS mode you must use this AT command: AT+QCFG="usbnet",3 In order to use again the ECM mode you must use this AT command: AT+QCFG="usbnet",1 Look for "Quectel_EC200T_Linux_USB_Driver_User_Guide_V1.0.pdf" for other AT commands Signed-off-by: Davide Fioravanti --- diff --git a/target/linux/ath79/dts/qca9533_kuwfi_c910.dts b/target/linux/ath79/dts/qca9533_kuwfi_c910.dts new file mode 100644 index 0000000000..a705aa8686 --- /dev/null +++ b/target/linux/ath79/dts/qca9533_kuwfi_c910.dts @@ -0,0 +1,194 @@ +// SPDX-License-Identifier: GPL-2.0-or-later OR MIT + +#include "qca953x.dtsi" + +#include +#include +#include + +/ { + compatible = "kuwfi,c910", "qca,qca9533";
