Firmware loaded without change

[Lothar]

Hi,
I changes some variable in my firmware.
This is not the first time, but startig after I reinstall my windows 7 I have a strange beahiour.
Arduino 1.0.6 told me that firmware is loaded but when I search the change into the control section of LCD I didn't see any change.
It seems that instead of what Ardiono software told me firmware is not loaded.
Someone can help me?

I have a geeetech prusa I3 pro W with GT2560 rev A+
I tryed to reinstal USB Driver...divverent version od arduino software...nothing.
Device manage see my board like a CH340...

I'm in a nightmare

try doing the initialize eeprom from the LCD after you have uploaded your changes. this worked for me when i was trying to change my z steps.

I can store Values from the control panel.
What is wrong is the loading phase from PC.
Probably my GT2560 rev A+ is broke

Have you tried to enable the EEPROM?

Sorry I really Junior

I checked into the configuration.h end eeepron apear enabled.

What I have is this beahviour....it is an example
If I change the Z offset from the printer and store it in memory....the values remain.
When I compile Marlin and load it to the printer...z offset value doesn't change.

is this related to the EEPRON?

Ok Wiliam
You are right. With the eepron enalbed the values arrive from it.
Disabling it all works.
Thanks to solve my question
