Firmware Upgrade
6.1 Upgrade Procedure
6.1.1 Host Setup
Host setup is very critical in upgrading the firmware. The following instructions are generic,
and have been tested at RHEL 4.6 and RHEL 5.3 - 32 bit. Your system may be different
and the commands should be adjusted accordingly.
1. Turn off the firewall for tftp to work. Type iptables -F or setup at the command line.
2. All the operators on the host side should be ordinary users which have "sudo" privilege
with NO password. To obtain "sudo" privilege, the operator should login as root, and
run "visudo" and add the below line at the end.
Example:
ec7987 ALL=(ALL) NOPASSWD: ALL
3. Setting up the tftp service:

Create the /local/tftpboot/COMX-P2020/current directory at host, and copy the
release file: COMX-P2020.bsp.tar.gz to the directory:
/local/tftpboot/COMX-P2020/current
[percy@localhost current]$ sudo chmod 777
/local/tftpboot/COMX-P2020/current
[percy@localhost current]$ ls -al COMX-P2020.bsp.tar.gz
-rwxr--r-- 1 percy percy 462501957 Dec 9 14:57 COMX-
P2020.bsp.tar.gz
[percy@localhost current]$

Extract all the BSP targets from the COMX-P2020.bsp.tar.gz:
[percy@localhost current]$ tar zxvf COMX-P2020.bsp.tar.gz
[percy@localhost current]$ ls -al
total 910224
