JTAG chains
I think the JTAG chains in blue are essential:
- Programming of the nanoFIP ProASIC3 from the JTAG header on the FMC-nanoFIP board
- Programming of the SB FPGA from the nanoFIP JTAG controller (NF-JC) with a bitstream coming through the WorldFIP bus (this passes from GPIOs on the FMC connector, not the dedicated JTAG ones)
The JTAG chain in pink though, is it really essential?:
- Programming the SB FPGA through the FMC-nanoFIP JTAG header or programming the nanoFIP FPGA from a header on the SB
- Would other boards, other than the DI/OT SB, need this chain?
