Hi Steve,

Have you been able to get any help on this? If not I can help, depending on what you're after. I've worked on several projects with that exact combination of components.

Hi, Sorry this post is not specific to FT products, but I noticed you guys are using KiCAD and I'm in the process of transitioning away from Protel 99. I just can't justify maintaining a Windows XP machine any longer just for this. I've tried Eagle but don't like the workflow of having to predefine ...

sorry for post without due diligence. turns out it was a firewall problem. Now all seems to be working ok

- can ping device
- can download new bin file over network using tftp client

Ok, 1 step forward, 1 step back. I can now ping device on the network, however having trouble opening tftp connection. When I look at connection on wireshark the Etherten is responding to the tftp request with destination unreachable (port unreachable) I'm using windows 7 tftp client, which is tryin...

Yes it does appear to be the power. Using a 7V plugpack solved the problem. Can't believe I went round in circles for days. When I tested with a normal ethernet sketch it must have been a different USB port, or maybe it was just borderline.

Thanks for the replies and advice

Hi, I've rechecked everything and all seems ok. If I reload the Uno bootloader and an ethernet sketch, I'm able to ping the device ok. I'm now using AVRDUDESS to load bootloaders in case I haven't setup the Arduino IDE correctly. I totally erase flash and eeprom, then load the tftpboot bootloader (a...

Alright, things are getting weird now. All following is on etherten with USBasp from freetronics. I have direct network cable between my PC and etherten with static IP settings on PC. I've tried many different combinations of tftp/network bootloader trying to get it to work, in all cases bootloader ...

Hi, Thanks for reply. I'm in the process of testing this out but am having lots of trouble getting bootloader to work. Would you be able to do an updated tutorial covering the changes required for latest IDE 1.6.1 (or even 1.5 or later). I'm using Etherten board with freetronics USBasp programmer. I...

Hi All, I'm about to try getting the tftp bootloader working on my system (EtherTen), but was wondering if I can program the network settings to EEPROM from within my application. - What are the EEPROM addresses used by the bootloader and what is the format of the data? I want to know if the followi...

Found the problem/s 1. after stopping client with client.stop, it was necessary to restart server with server.begin } // end while (connected) client.stop(); server.begin(); } // end if(client) 2. I was using D13 as a GPIO to indicate when client was connected, however I forgot that 13 is used by SP...
