TNT firmware mainly consist of the several bitstreams necessary to the FPGA operation.
The bitstreams can be formatted differently, depending on the way they are downloaded to the FPGA.
.bit format, to be downloaded directly to the FPGA via the JTAG port ; hence, this way of programming is volatile and the configuration is lost when the power is off
.bin format (only Virtex II), to be downloaded to a non volatile on board FLASH EPROM. From here, the bitstream can be charged to the FPGA. This opperation must be done each time the board is booted. Refer to TNT documentation for details on how this works.
.mcs format, to be stored in non volatile EEPROM’s memories via the JTAG port. At boot time, the FPGA’s recover the contents of its corresponding EEPROM’s. No special manipulation is necessary to configure.
For VHDL upgrading instructions.

Some firmware is also stored in the FX2 USB chip which has in charge all the low level USB communication and act as some gateway to both FPGA. This firmware (which contain the card number) is stored in some IIC EEPROM.
