I had to reset to factory settings because I cannot change the state of gpio2.
Now, I dont have access to Netzer, and I dont know how I can download the firmware.
In this link
http://www.mobacon.de/wiki/doku.php/en/netzer/resettofactory show that If the release is older that 1.5, I have to solder a 1K resistor. I dont know what my version is, I only know that the Netzer was bought 6 month ago, so I supose it has to have a newest version.
So, I think I have to upload the firmware via TFTP, is all right?
Thank you so much.
