Sundance Multiprocessor Technology SMT702 + SMT712 FPGA Configuration

Sundance Multiprocessor Technology CPLD + Flash Configuration  The FPGA in both the SMT702 and SMT712 are configured at power up from a selectable address in on-board flash  A CPLD manages accessing the flash chip for configuration, and reading/writing from the Host – transparent from user  Flash size for both systems = 256Mbit

Sundance Multiprocessor Technology SMT6002  The SMT6002 is the provided Host application used to access the flash chip for loading and deleting bitstreams via a connection block in the FPGA to the CPLD.  The tool will automatically detect the type of board and read the contents of the flash when launched.  The default firmware (at address 0x0) is read-only and so protected from deletion. This is so that even after custom bitstream booting, there is always a recoverable link to the flash for correction.

Sundance Multiprocessor Technology Changing the Flash Contents  Deleting Select the bitstream to remove and press ‘Delete’. There is a ‘Safe-erase’ option which will remove every bitstream in flash except for the default bitstream at address 0x0. There is an option to remove the entire flash, but requires a modification to the Windows Registry.  Adding After a bitstream path has been chosen, select a position in flash to load the bitstream. With the ‘Basic’ addressing mode chosen, the offset address will be adjusted automatically for the board accessed. Comments and Version information may be optionally loaded as well if desired.

Sundance Multiprocessor Technology Bitstream Configuration  The position offset address in flash can be chosen by switch selection (SW1). SW1 has four, on/off switches integrated, but only toggle 1 and 2 are used.  The address to be booted can be counted in binary.  Position 0, (offset 0x0 default) is SW1(1 = off, 2 = off).  Position 1, (offset 0x800000) is SW1(1 = off, 2 = on).  Etc.  The FPGA can also be reconfigured after power up by selecting the bitstream, then ticking ‘Reconfigure FPGA from Flash’. Press ‘Commit’.  The approximate time to configure the FPGA from flash and be ‘alive’ to the Host is approximately 140ms.
