andyfive Posted July 25, 2014 Report Share Posted July 25, 2014 hello everyone,i am building my own papilio pro. ive got 10 boards on the way and enough parts to populate two. my question is thiis:there is an eeprom connected to the ftdi chip. what information needs to be placed on this eeprom, and will i have to use an external programmer before soldering on the board, or can i use the ftdi to program the eeprom? thanks in advance! -Andy Link to comment Share on other sites More sharing options...

TomKeddie Posted July 25, 2014 Report Share Posted July 25, 2014 Andy,We built a few papilio pros last year in a workshop. Had some issues with flash programming that a few ground wires fixed. Yes, as above blank eeprom is fine.Jack posted the bom for me somewhere in the forums.Cheers,Tom Link to comment Share on other sites More sharing options...
Jack Gassett Posted July 28, 2014 Report Share Posted July 28, 2014 Hey Andy, Everything will still work even if you do not solder on the EEPROM chip. The only bad thing you can do is to solder it on the wrong way, which I've seen before, which will cause the FTDI chip to not respond. Blank or not populated at all is fine, the Papilio Pro does not use the eeprom chip for default usage. Jack. Link to comment Share on other sites More sharing options...
