BCM93349DCM Manual Upgrade Fireware Guide

I. Preset conditions

1, the PC has been installed TFTP Server, such as TFTPD32;

2, the PC has been installed USB to serial port drive, can communicate with CM through the serial port;

3, the PC has a compiled cm Fireware.

Second, the hardware connection

PC and CM are connected via serial port and network Port respectively.

Third, serious attention

Both cm and PC IP are manually configured at the time of upgrade!
CM ip = Board IP
PC IP = Board TFTP Server IP
Because CM starts by pressing p to enter upgrade mode, the DHCP module is no longer started, so CM does not assign IP addresses to the PC via DHCP.

Iv.. Upgrade process

Through the serial port operation, there are three steps: Setting up IP to establish communication--using TFTP upload fireware--reboot.

The bold Blue Word is the information you want to enter, and you do not need to modify the direct carriage to continue.

Enter ' 1 ', ' 2 ', or ' P ' within 2 seconds or take default ...
