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?
