EEPROM and Firmware Upgrade
The MXH832 design uses a microcontroller to implement the PCIe CMI protocol and other maintenance functions. Dolphin may
from time to time publish updated firmware for the microcontroller or EEPROM data for the card. Please contact Dolphin for
instructions on how to upgrade the MXH832. Please note that standard Microsemi firmware tools cannot be used to upgrade the
firmware.
Identifying the Card
The card has a label-
sticker with the serial number in the format ‘
MXH832-YY-
ZZZZZZ’, where YY de
notes the card revision (e.g. BB)
and ZZZZZZ denotes the serialized production number (e.g. 012345)
–
this whole string makes up the serial number of the card (i.e.
MXH832-BB-012345).
You can also get this information using lspci in Linux:
First, identify the devices for the Dolphin Host card:
Than run lspci, and identify the card. It will show up as something like
# lspci | grep “Device 8532”
01:00.0 PCI bridge: PMC-Sierra Inc. Device 8532
01:00.1 Memory controller: PMC-Sierra Inc. Device 8532
02:00.0 PCI bridge: PMC-Sierra Inc. Device 8532
