When I selecct Config - Firmware I get a pane showing Marlin Firmware EEPROM Settings. But everything is zeroed. Nothing I do seems to matter, it comes up all zeroes. ? ? ?
Could it be that you compiled marlin without eeprom support?
How do you compile Marlin with eeprom support? I keep getting no start signal detected- forcing start and eeprom is greyed out in the config drop down in RH.
"no start signal detected- forcing start" is often a sign that baud rate is wrong (except printers that can not reset over usb). Can you do other operations except eeprom?
For marlin related questions, please ask marlin experts, I'm not familiar with it.
