Buffered IDE is mostly a niche thing. It is for long IDE cables, most people use short CF adapters, so there is no real need for the extra expense and time to install the chips.Hanzu wrote: ↑Mon Oct 05, 2020 12:43 pmHi
I thought buffered IDE is always better than unbuffered, so why so many wants unbuffered?
Adding some 74VHC245PW to IC4, IC5 and IC6 and removing some SMD resistor networks is no problem, but it would be nice to know the benefits of each option (Buffered and Ubuffered) before ordering other parts. Almost all pictures of Googled TF536 are are Unbuffered (no IC4, IC5 and IC6). Only one found as buffered.
Also half of the Googled TF536 pictures are without JTAG1 connector and that makes me wonder how do those people program Xilinx?
You can program the board using pins inserted into the JTAG holes on the board, again, no real need to add something that isn't used.
