Step 5: Tell the E10 to use the newly programmed-in firmware image.
Do a
printenv
command. You should see output like the following:
U-Boot> printenv
bootargs=console=ttyS0,115200 root=/dev/mtdblock1
mtdparts=atmel_nand:16M(kernel)ro,120M(rootfs),-(other) rw
rootfstype=jffs2
bootdelay=3
baudrate=115200
autostart=yes
ethact=macb0
bootcmd=nboot 0x21000000 0 a0000
ethaddr=00:1c:2c:ff:b5:eb
stdin=serial
stdout=serial
stderr=serial
Environment size: 281/131067 bytes
U-Boot>
Enter the following command and press the
<Enter>
key:
set bootcmd nboot 0x21000000 0 a0000
Step 6: Correct the E10's MAC address if needed.
Look at the output of the
printenv
command and see what the E10's MAC address is
currently set to.
In the output of the
printenv
command, this field is labeled
ethaddr
.
If it matches the label on the bottom of the E10, no action is needed.
If instead it shows something like
00:1c:2c:ff:ff:ff
, then the correct Ethernet MAC
address still needs to be set.
Note:
Type carefully during this step! The E10 only allows the MAC address to be changed
ONCE. If you make a mistake and set your Ethernet address incorrectly, refer to the
chapter
Recovery Procedure
on page 40 for help.
If your E10 does in fact need its MAC address set, use a command of the form:
set ethaddr 00:1c:2c:xx:yy:zz
Where
xx:yy:zz
should be replaced with the correct three hexadecimal bytes from the
label on the bottom of your E10.
Step 7: Save your changes.
Use the command
saveenv.
Step 8: Exit U-Boot and startup Linux.
Use the U-Boot command
reset.
