4.4 Reserved Factory Programming Jumpers
The CDB5366 Evaluation Board has two reserved headers, J15 and J8, that are used to factory program
the Cygnal^® 8051 microprocessor and the Xilinx® FPGA so that the FlexGUI interface operates correctly.
Caution! Do not apply power or shorts to these two jumpers as device damage could occur.
