Opening the case

Note: This will void your warranty!

Remove rear sticker and the two screws under it. Pull and remove left side cover.

Serial

port.serial general information about the serial port, serial port cable, etc.

After opening the case, you will find jumper J14 near the cpu with the big heatsink. This is the console serial port, with pins assigned as:

Pin 1 Pin 2 Pin 3 Pin 4
VCC (3.3v) Gnd TX RX

Console serial port parameters

  • Speed (baud rate): 115200
  • Bits: 8
  • Parity: None
  • Stop Bits: 1
  • Flow Control: None (both hardware and software flow control)

Connect your serial adapter (a generic CH340 USB to TTL adapter set to 3.3v is known to work) to J14 with crossed RX/TX as follows:

J14 Pin 1 Pin 2 Pin 3 Pin 4
Serial Adapter Not Connected Gnd RX TX

After powering on the router, type Control-C to interrupt the boot sequence until you see a CFE> prompt, at which point you will be in the Broadcom Common Firmware Environment (CFE) firmware interface.

JTAG

port.jtag general information about the JTAG port, JTAG cable, etc.
