General Outline for Bootstrapping using PMON

Preparing Target Hardware and Connections

    • Connections:
      • Host machine Ethernet to hub (I configured as 192.168.1.1)
      • T-Cube Ethernet to hub (I configured as 192.168.1.2)
      • Connect serial cable between T-Cube and host machine
        • Serial1 connector to interface module serial port
        • Other end of null-modem cable to first serial port (ttyS0) on the Linux host machine

Preparing Host Software

  • Download and place files in /tftpboot
  • Make sure tftpd is ready to run
  • Confirm minicom is configured to access /dev/ttyS0, at 115K N81

Using PMON to Boot the Kernel

  • Root filesystem is NFS

Building the Kernel

Here are some commands I used to build the kernel:

  • cd celinux-040503/
  • export PATH=/usr/local/bin:$PATH
  • cp arch/mips/defconfig-tcube .config
  • make ARCH=mips CROSS_COMPILE=mipsel-linux- menuconfig
    • disable XIP
  • make ARCH=mips CROSS_COMPILE=mipsel-linux- dep
  • make ARCH=mips CROSS_COMPILE=mipsel-linux-

Preparing the Kernel to Download

  • cp vmlinux /tftpboot/

Starting the NFS daemon

  • /etc/rc.d/init.d/nfs start

Setting Environment Variable and Write Environment Value on T-Cube

  • minicom (set to /dev/ttyS0)
  • Set environment variable
    • Set variable tty0 (I used "set tty0 115200")
    • Set variable netaddr (I used "set netaddr 192.168.1.2")
    • Set variable bootaddr (I used "set bootaddr 192.168.1.1")
    • Set variable bootfile (I used "set bootfile vmlinux")
  • Write environment value
    • Employed "write_env" command

Downloading the Kernel to T-Cube

  • minicom (set to /dev/ttyS0)
  • Download the kernel
    • Employ "boot" command
    • As "boot" command completes, "Entry-address" appears.

Booting the Kernel

  • Employ "go" command (I used "g -e Entry-address")
