SubjectRe: [PATCH 0/3] FPGA Manager support for FPP via FT232H FT245-FIFO
Hello Alan,

many thanks for your response.
Well, I am following the whole discussion from the very start and for my
taste it is too superficial - don't know whether this is the right
wording. Please get me right. We need some kind of implementation
specification or a sample way on how to implement stuff. At some point I
honestly lost track, thus I was asking for a summary so in the end the
result is what we want. If it is clear to everyone what shall be done it
should not be kind of a big deal to quickly sum it up which I/we would
highly appreciate.

Many thanks
Eric
