EEPROM and Firmware Upgrade
The PXH822 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 PXH822. Please note that standard PLX 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 ‘PXH8
22-YY-
ZZZZZZ’, where YY denotes 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.
PXH822-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
Second, do
This shows the card as revision 0x4242
(hexadecimal values of the ‘
BB
’ letters in the ASCII table), with the production number
0x0000000A (0000010 in decimal).
