X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=a1deab0ec9ced8f1a2c997483efc1fc6e364ae34;p=openwrt%2Fstaging%2Fxback.git

ramips: add support for ipTIME T5004

ipTIME T5004 is a 5-port Gigabit Ethernet router, based on MediaTek MT7621A.

Specifications:
* SoC: MT7621AT
* RAM: 128 MiB
* Flash: NAND 128 MiB
* Ethernet: 5x 1GbE
  * Switch: SoC built-in
* UART: J4 (57600 baud)
  * Pinout: [3V3] (TXD) (RXD) (GND)

Installation via web interface:
1.  Flash **initramfs** image through the stock web interface.
2.  Boot into OpenWrt and perform sysupgrade with sysupgrade image.

Revert to stock firmware via recovery mode:
1.  Press reset button, power up the device, wait >15s for CPU LED
    to stop blinking.
2.  Upload stock image to TFTP server at 192.168.0.1.
