Up to this point we've always booted the Beagle into Linux and worked from there. Now it's time to learn what has to happen before we can run Linux. To do this you need to look at the output of the serial port so see the boot sequence.

Booting Up

You need to attach a 3.3V FTDI cable to see the boot sequence.

Look for the black lead which is marked with a little triangle. This connects to the pin with the white dot next to it.

Boot up your bone and connect to the serial port using the screen command. Hit return and log in. You may need to make yourself owner of /dev/ttyUSB0 before running screen.

host$ sudo chown $USER:$USER /dev/ttyUSB0
host$ screen /dev/ttyUSB0 115200
Debian GNU/Linux 7 yoder-debian-bone ttyO0

default username:password is [debian:temppwd]

While in screen hit Ctrl-a ? to learn how to log data with screen. Turn on logging and capture the boot and shutdown data that is presented on this page. Keep it in a file where you can refer to it later.

Shutdown

Now shutdown and be ready to hit return when you get the u-boot prompt.

bone$ reboot

These first messages are from the kernel shutting down.

U-Boot Starting

The following messages are the boot sequence.

Discovering what boot does

Your goal is to discover what happens when the boot command is run.

U-Boot# help boot
boot - boot default, i.e., run 'bootcmd'

Usage:
boot 
U-Boot# print bootcmd
bootcmd=gpio set 53; i2c mw 0x24 1 0x3e; run findfdt; setenv mmcdev 0; setenv bootpart 0:1;
run mmcboot;gpio clear 56; gpio clear 55; gpio clear 54; setenv mmcdev 1; setenv bootpart 1:1;
run mmcboot;run nandboot;

Figure out what's happening above by 'pretty printing' bootcmd. That is, properly format the code so you can follow the flow.

gpio set 53;
i2c mw 0x24 1 0x3e;
run findfdt; 

setenv mmcdev 0;
setenv bootpart 0:1;
run mmcboot;

gpio clear 56;
gpio clear 55;
gpio clear 54;
setenv mmcdev 1;
setenv bootpart 1:1;
run mmcboot;
run nandboot;

You can dig further by printing the scripts being run. For example the findfdt script.

U-Boot# print findfdt
findfdt=
if test $board_name = A335BONE;
   then 
   setenv fdtfile am335x-bone.dtb;
   setenv fdtbase am335x-bone;
   fi;
if test $board_name = A335BNLT;
   then 
   setenv fdtfile am335x-boneblack.dtb;
   setenv fdtbase am335x-boneblack;
   fi;
if test $board_name = A33515BB;
   then 
   setenv fdtfile am335x-evm.dtb;
   fi;
if test $board_name = A335X_SK;
   then 
   setenv fdtfile am335x-evmsk.dtb;
   fi;
if test $fdtfile = undefined;
   then echo WARNING: Could not determine device tree to use;
   fi;

Or take a look at mmcboot

mmcboot=
mmc dev ${mmcdev};
if mmc rescan;
  then 
  gpio set 54;
  echo SD/MMC found on device ${mmcdev};
  setenv bootpart ${mmcdev}:1;
  echo Checking for: /uEnv.txt ...;
  if test -e mmc ${bootpart} /uEnv.txt;
     then 
     if run loadbootenv;
        then 
        gpio set 55;
        echo Loaded environment from ${bootenv};
        run importbootenv;
        fi;
     if test -n ${cape};
        then 
        if test -e mmc ${bootpart} ${fdtdir}/${fdtbase}-${cape}.dtb;
           then 
           setenv fdtfile ${fdtbase}-${cape}.dtb;
           fi;
        echo using: $fdtfile...;
        fi;
     echo Checking if uenvcmd is set ...;
     if test -n ${uenvcmd};
        then 
        gpio set 56;
        echo Running uenvcmd ...;
        run uenvcmd;
        fi;
     echo Checking if client_ip is set ...;
     if test -n ${client_ip};
        then 
        if test -n ${dtb};
           then 
           setenv fdtfile ${dtb};
           echo using ${fdtfile} ...;
           fi;
        gpio set 56;
        echo Running nfsboot ...;
        run nfsboot;
        fi;
     fi;
  echo Checking for: /${script} ...;
  if test -e mmc ${bootpart} /${script};
     then 
     gpio set 55;
     setenv scriptfile ${script};
     run loadbootscript;
     echo Loaded script from ${scriptfile};
     gpio set 56;
     run bootscript;
     fi;
  echo Checking for: /boot/${script} ...;
  if test -e mmc ${bootpart} /boot/${script};
     then 
     gpio set 55;
     setenv scriptfile /boot/${script};
     run loadbootscript;
     echo Loaded script from ${scriptfile};
     gpio set 56;
     run bootscript;
     fi;
  echo Checking for: /boot/uEnv.txt ...;
  for i in 1 2 3 4 5 6 7 ;
     do setenv mmcpart ${i};
     setenv bootpart ${mmcdev}:${mmcpart};
     if test -e mmc ${bootpart} /boot/uEnv.txt;
        then 
        gpio set 55;
        load mmc ${bootpart} ${loadaddr} /boot/uEnv.txt;
        env import -t ${loadaddr} ${filesize};
        echo Loaded environment from /boot/uEnv.txt;
        if test -n ${dtb};
           then 
           setenv fdtfile ${dtb};
           echo Using: dtb=${fdtfile} ...;
           fi;
        echo Checking if uname_r is set in /boot/uEnv.txt...;
        if test -n ${uname_r};
           then 
           gpio set 56;
           echo Running uname_boot ...;
           setenv mmcroot /dev/mmcblk${mmcdev}p${mmcpart} ro;
           run uname_boot;
           fi;
        fi;
     done;
  fi;

U-Boot print

It might be helpful to print the contents of all the variables and save it for future reference.

Looking on the FAT partition

The SD card you have been using has 2 partitions on it. Partition 1 is a small FAT partition. These are the files you see appear when you first boot the bone. This used to contain the boot loaders.

The second partition is ext4 and contains the root file system. These are all the other files.

You can see the FAT partition with:

bone$ mkdir /mnt/fat
bone$ ls /mnt/fat    # Hmm....  nothing there
bone$ mount /dev/mmcblk0p1 /mnt/fat
bone$ ls /mnt/fat    # and now there is
App          Docs     ID.txt       nfs-uEnv.txt  README.md  START.htm
autorun.inf  Drivers  LICENSE.txt  README.htm    scripts    uEnv.txt

If you look in /boot you'll see the files used to boot.

bone# cd /boot
bone# ls -F
config-3.8.13-bone64      SOC.sh                    uEnv.txt
dtbs/                     System.map-3.8.13-bone64  vmlinuz-3.8.13-bone64*
initrd.img-3.8.13-bone64  uboot/

vmlinuz-3.8.13-bone64 is the kernel.

Look in uEnv.txt

beagle$ cat uEnv.txt

These are the arguments that are passed to the kernel when it boots. Try editing the file and removing quiet, then reboot. You should see many more boot messages.

Kernel boot messages

Here's what I got with quiet removed.
