You don't need any tpdd device, you just need any modern pc and a usb serial cable and some free software.
If you are even in the market a rex at all in the first place, then automatically a usb serial adapter and a serial cable is hardly a special unreasonable extra burden. It's like complaining about the price of a car wash for your Ferrari The only problem would be if the cpld programming is not the same for 100 vs 200. If not, then it would probably not be possible to take a 100 rex and re-flash it to a 200 rex using only a 200. Someone could just try it, or Stephen could probably just say. I have a 200, but I don't remember if Stephen has made the 200 version firmware available yet. Then again, even if you do need a xilinx programmer to reflash the cpld, that is only $30. The software is large to download, and a pain to activate and get working, but completely free. I have a hard time working up much sympathy over simply not wanting to spend the time and effort to follow some recipe directions, after all the stuff the builder had to do to get an M100 version built and working. It's not totally unreasonable if M200 users have to re-flash. -- bkw On Oct 5, 2017 6:24 PM, "Jim Anderson" <jim.ander...@kpu.ca> wrote: > > -----Original Message----- > > > > Apparently, the only difference btwn the 100/102 REX and the 200 REX > > is the software load.
