Overview

Asus RT-N53 is Broadcom-based board with:

  • BCM5358UB0 SoC, MIPS74K, 500MHz
  • 32MiB RAM
  • 8MiB flash (SPI-mx25l)
  • WiFi BGN chip
  • Ether Roboswitch 5x100M

How to build

  • Check out freebsd-HEAD to /path/to/src
  • clone the freebsd-wifi-build repo to /path/to/freebsd-wifi-build
$ cd /path/to/src
$ ../freebsd-wifi-build/bin/build bcm-trx

How to flash (using tftp)

  • Setup your host as 192.168.1.100
  • Plug into a LAN port
  • On host, start tftp session from /path/to/tftpboot:
$ cd /path/to/tftpboot
$ tftp 192.168.1.1
tftp> mode binary
tftp> put bcm-trx.trx
  • Power on router
  • TFTP establishes connection to router and start writing session
  • Wait for 2-3 minutes after TFTP session completion (flash is slow for writing, so it takes few minutes).
  • Reboot router

It's easier to verify this with the serial port wired up.
