We are using FPGA Xilinx Spartan-6 P/N XC6SLX150-2CSG484I. We have identified two labeling configurations on the components. One with the additional labeling "NNBC9-00" (under the word TAIWAN), and the second without this additional labeling. What is the difference between them?
The problem is that on the component with the additional labeling NNBC9-00 we are unable to load software to the component (there is no communication during the loading protocol! Or maybe it has different "speed grade"!). On the component without the additional labeling, we are able to load software, and we see that there is communication with the component.
