Resolve a possible Spartan6 MultiBoot Field Upgrade dead lock. Spartan 6 MultiBoot boots to Normal bit normally. If normal bit has CRC errors or it has time out errors for not found the bit header, Spartan 6 falls back to Golden bit automatically. To solve this issue, we can use the IPROG feature of Spartan6 without using MultiBoot. In UG380, Chapter Reboot Using ICAP SPARTAN6 , it describes a method to control start address of the bitstream. The boot sequence can be:. Click here to cancel reply. On How ...

The latest Xilinx demo boards all use SiliconLab CP210x USB2UART chip to communicate to PC because the modern PC all removed the 9 pin serial port. Using USB to transfer UART protocol can also save board space and make the power design of the demo board easier. SiliconLab provides driver for Windows, Linux and Mac. .
