5.3 Firmware Update Procedure
The aTCA-6250 supports firmware update (IPMC FW, BIOS, FRU) over various interfaces
(LAN, KCS, serial interface or IPMB). Please follow the procedures listed below to update
the IPMC firmware.
Note: IPMB-0 will be disabled during the process of upgrading IPMC firmware. This is a
limitation of the IPMC controller (SmartFusion A2F500)
5.3.1 Update Over Serial Interface
The following IPMItool command line parameters are used for communicating with the carrier
IPMC via a serial interface:
 -I serial-terminal
This parameter instructs the IPMItool utility to use the serial interface for communications
with the carrier IPMC.
 -D <dev[:baudrate]>
This parameter specifies the serial device and baud rate settings to use. For Linux hosts, the
serial device is the system path to the device node (e.g. /dev/ttyS0).
Perform the following steps to update the IPMC firmware:
Step 1: Prepare an external host PC with Linux OS and connect it to the serial port on the
aTCA-6250 via the COM port (USB Mini-B on the front panel). Put the IPMItool utility and
new firmware image on the host PC. Enter the following command:
Step 2: Enter “y” when prompted and wait until the string “firmware update procedure
successful” is displayed.
