1. Download the firmware and place it in your TFTP server's repository
2. Remove the top cover from the IP0x and install the small RS232 daughter board that
was included in the package on J8 as shown below (if there's a jumper here remove
it temporarily, and be sure to place it back once done or the unit might not boot).
3. Configure your client application to use 115,200 baud, 8 data bits and no parity.
Also make sure Hardware Flow Control is turned off, and that you're using the
correct port (minicom might be set to use /dev/tty0 by default instead of
/dev/ttyS0)
4. Connect the cable between the RS232 daughter board and your PC
5. Power on the IP0x
6. Press Enter when you get the prompt 'Hit any key to stop autoboot'
7. Enter the following commands ("ip04>" and "root:~>" signify the prompt and are
not part of the command itself, and you may replace the IP addresses with ones
suitable for your network. Do not copy/paste the commands.):
ip04>setenv autostart
ip04>setenv ipaddr 192.168.1.100
ip04>setenv netmask 255.255.255.0
ip04>setenv gatewayip 192.168.1.1
ip04>setenv serverip 192.168.1.200
(Notes: "serverip" refers to your TFTP server. The addresses that you specify here
are only used during the flashing process - when booting the new firmware it will
attempt to use the IP address 192.168.1.100 and if that fails it will attempt DHCP
instead. You may review your settings using the 'print' command.)
ip04>save
ip04>tftp 0x1000000 uImage.ext2
