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
- Connections:
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")
