I use XCF128X on my board to support virtex6 FPGA XC6VLX240T, but I cannot program this flash probably.
I read ug438 and check my schematic to the correct pin connections in the data sheet. I use slave selectmap mode .
the m[2:0] = 110 and the frequency of cclk is 40MHz
I use iMPACT 11.5 and the log is attached as following:
Boundary-scan chain validated successfully.
