FPGA
The FPGA (Field Programmable Gate Array) is a Xilinx Virtex-II device.
It implements the following communication resources:
• Six comport interfaces
• Two 32-bit Sundance digital bus interfaces
• One global bus interface
Version control
Revision numbers for both the boot code and FPGA firmware are stored in the Flash
ROM during programming as zero-terminated ASCII strings.
The SMT6001 utility can be used to display the version numbers of the bootloader
and the FPGA data.
Firmware versions
The SMT6001 utility includes the latest version of the bootloader and the latest
version of the FPGA data that implements the FPGA architecture described in the
SMT6500 help file .
Note that the new firmware does not support the DSPA_SWITCH: only two 32-bit
SDB interfaces are presented on the TIM connectors and their configuration is fixed.
The configuration of the six internal comports is also fixed.
Customers whom wish to use the old firmware that supported the 16-bit options and
the DSPA_SWITCH can obtain it
from our support web forum .
Reprogramming the firmware and boot code
The contents of the flash ROM are managed using the SMT6001 utility. This includes
the latest firmware and bootloader along with complete documentation on how to
reprogram the ROM. The utility assumes that you have Code Composer Studio
installed and that it has been configured correctly for the installed TIMs. The
Sundance Wizard can help you with this.
