From: Sergio Paracuellos Date: Sun, 4 Apr 2021 06:50:26 +0000 (+0200) Subject: ramips: add support for HiLink HLK-7621A evaluation board X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=eb00fb8f7153535512b2dad365e76a2bc0dfb6c1;p=openwrt%2Fstaging%2Fxback.git ramips: add support for HiLink HLK-7621A evaluation board Specifications: - SoC: MediaTek MT7621AT - RAM: 256 MB (DDR3) - Flash: 32 MB SPI NOR 44MHz - Switch: 1 WAN, 4 LAN (Gigabit) - LEDs: 1 WAN, 4 LAN (controlled by PHY) - USB Ports: 1 x USB2, 1 x USB3 - WLAN: 1 x 2.4, 5 GHz 866Mbps (MT7612E) - Button: 1 button (reset) - UART Serial: UART1 as console : 57600 baud - Power: 12VDC, 1A Installation: Update openWRT firmware using internal GNUBEE uboot: https://github.com/gnubee-git/GnuBee-MT7621-uboot By HTTP: Initial uboot address is http://10.10.10.123, your address needs to be 10.10.10.x, and mask 255.255.255.0. By TFTP: Uboot is in client mode, the address of the firmware must be tftp://10.10.10.3/uboot.bin Recovery: Manufacturer provides MTK OpenWrt 14.07 source code, compile then flash it by uboot. HLK-7621A is a stamp hole package module for embedded development, users have to design IO boards to use it. MAC addresses: - u-boot-env contains a placeholder address: > mtd_get_mac_ascii u-boot-env ethaddr 03:17:73:ab:cd:ef - phy0 gets a valid-looking address: > cat /sys/class/ieee80211/phy0/macaddress f8:62:aa:**:**:a8 - Calibration data for &pcie2 contains a valid address, however the zeros in the right half look like it's not real: 8c:88:2b:00:00:1b - Since it's an evaluation board and there is no solid information about the MAC address assignment, the ethernet MAC address is left random.
