Board 1.1 wont upload to 1.8, 1.6 is OK.

[Mongo]

First off, great product! Thanks for the amount of time and effort you put in!

I bought the board for a 1.1 because I wanted to mess with the RTC option ( I didnt realize 1.4 was coming out a couple days after I ordered). Also, I seem to want to make things harder than they should be. Anyway, I can get the board running with 1.6 and all is well. When I try to upload 1.8.1 with TinyUSB programmer, it says complete, but I cant login to the board. Doesn't list as an attached device in the router menu. If I roll back to 1.6, all is well. I even tried brand new Atmega's with and without optiboot...

Any ideas what i may be doing wrong? Thanks!

I am not sure. I just tried it on my 1.1 board and everything is working fine. Make sure you are uploading the hex file from the compiled/v1.1 folder, not v1.2 or other folders.

Note that since you are using TingUSB programmer to upload, the bootloader (e.g. optiboot) does not matter because it will be overwritten by the programmer.

Thanks for answering Ray! Much appreciated!
Worked with it a few hours tonight, flashing 1.8 or rolling back to 1.6. Upgraded router to latest software, tried to ISP load a new blank chip in a regular Arduino board, still nothing with 1.8. Does 1.8 default to a static IP? I even tried running AngryIP to see everything that pings on the router. Totally stumped here...

[Ray]

The only thing I could think of is perhaps you have accidentally changed the fuse bits. The pre-programmed mcus are all set to use 8MHz clock. Maybe you have changed it to 16MHz by accident. To change the fuse bits back, use:

avrdude -c usbtiny -p m328p -B 250 -F -U lfuse:w:0xe2:m -U hfuse:w:0xd1:m -U efuse:w:0x06:m

then

avrdude -c usbtiny -p m328p -B 1 -F -U flash:w:firmware1.8.1.hex

to flash the firmware again.

Well you did mention that firmware 1.6 works, so I am not sure why 1.8 doesn't work. Do you see anything displayed on the LCD?

[Mongo]

Ran those commands like you suggested and same thing. No display- I think I smoked it by putting it in backwards when I first built it, I should have looked at the pictures better. New one is on the way, hopefully shows up today... Thanks again.

Got it!
Once I got a display on it ( had to wire it up with a breadboard, pins didnt match the one I got off Ebay), I was able to see that even with 1.8.1 it was not getting an IP from the router. I manually set an IP and all is well!
Now I just have to figure out if I want to keep the display ( and how to rewire it and make it fit the case) or pull it. I like it, its green letters on black...

Thanks again for your help and the great product!

OK, that's good to know. Thanks for the update.
