The JTAG-chain: JTAG<->ХС3S1400АN<->XСF04S<-> XСF02S<->JТАG.
iMPACT can configure any device.
xc3sprog can configure first (ХC3S1400АN) and last (ХCF02S) devices.
When I try to configure middle PROM by using command: xc3sprog -c pp -v -p 1 01xcf04_0.mcs:w::MCS
I see error message:
"incorrect record checksum found in MCS fileRequested operation (offset 0, length
737354 bytes) exceeds PROM space (4194304 bits)
Total bytes sent: 17"
Where is my error?
Thanks!
P.S.: two PROMs are required for one bitstream for FPGA XС3S1400АN.
