From b4086f44cd8a739458a0fd12cfaf684515507614 Mon Sep 17 00:00:00 2001 From: "Leon M. Busch-George" Date: Fri, 13 Oct 2023 12:44:11 +0200 Subject: [PATCH] mediatek: add support for YunCore AX835 MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Hardware specification: SoC: MediaTek MT7981B 2x A53 Flash: 16MB NOR RAM: 256MB Ethernet: 2x 10/100/1000 Mbps Switch: MediaTek MT7531AE WiFi: MediaTek MT7976C Button: Reset Power: DC 12V 1A, PoE 802.3af 48V Flash instructions: Option #1 - SSH I was able to SSH into the stock firmware of my device. 1. Attach the router to the network 2. Use scp (-O) to copy the sysupgrade image 3. Connect using SSH and run `sysupgrade -n` Option #2 - U-Boot One way to use the bootloader for flashing is using TFTP: 1. Connect to the router using an ethernet cable 2 Spin up a TFTP server serving the sysupgrade file 3. Open the case and attach a UART 4. Attach power to the router and interrupt the countdown by pressing any key 5. Select option #2 (Upgrade firmware) 6. Enter IP address information and image name 7.
