CPLD Upgrade
The CPLD offers the capability to reprogram its configuration data under host software control.
The procedure is not FAIL-SAFE status. This means, if a reprogramming procedure fails, the
whole card becomes unusable and needs to be reprogrammed via hardware (download cable).
CPLD can be upgraded by using the following procedure:
1. Boot the OS with PCIE8120 drivers installed and new CPLD image available.
2. Initialize the card by using the command
"/opt/bladeservices/bin/pcie8120-
init"
3. Erase the old CPLD image by using the command.
"/opt/bladeservices/bin/pcie8120-tool --dev=cpldx --
flasherase=cfg"
4. Program the CPLD with new firmware image
.
"/opt/bladeservices/bin/pcie8120-tool --dev=cpldx --
flashwrite=cfg 0 <file_new_cpld_fw_image>"
5. Powercycle the board.
