POST | BMM | BBR | Boot code | Recovery code | LCA (Xilinx)

POST

Power On Self Test code for the MCE board. Runs between BOOT and the Main Firmware when the machine is powered on.

BMM

The BMM programming card is used to load the Boot Block Recovery (BBR) code. The *bmm.bin files contain both the BBR code and the Boot code.

BBR

Boot Block Recovery Code. This code runs from the protected flash boot-block sector and is only re-programmable by using the BMM card. See BMM programmable card for downloads.

Boot code

Runs from a field erasable flash sector. Allows downloading of the main firmware using the diagnostic or workstation serial ports. 

Recovery code

This firmware is downloaded over the MCE diagnostic serial port, when the BBR is running. Use Bload.Exe utility v1.09 or newer. Normally this will never be required, unless the BBR could not find valid Boot code.

LCA (Xilinx)

This LCA or FPGA image is downloaded over the diagnostic serial port using the download command in Service Shell.  'Xilinx' is the name of the FPGA chip used on the MCE board and is the term often used to describe the image that is loaded into the FPGA chip.  If you can't find the LCA/XILINX file you think you need or if you have any questions please contact Greg Hall.
