first time using this service. i'm not sure if i'm missing something or it's an issue with tonight's build or what.
i have formatted and reflashed with two different sd cards, one 512mb and one 8gb. both have the same issue and formatted as fat32. both have worked for this printer in the past, storing eeprom appropriately.
m503 shows it reads the flashed defaults. m502 respond ok P15B3. m500 is a deluge of "echo:Error writing to EEPROM!".
i've initialized the eeprom through the lcd, restored and saved that way and rebooted and still no. i unplugged my sd card extender and slotted the card directly because that was a new part and i thought it might be the culprit; nope. both cards, same firmware (options off the builder; bltouch, ubl, baby stepping, sd card supported was checked, nothing extravagant).
the lcd menu chirps like it stores it. no error. it doesn't save anything though, one reboot clears any changes.
did i miss an option to emulate eeprom on the sd card? i figured that's what "sd card support" was partially for. i did not see a specific option for this.
please help, i wanted to pay you all to take firmware problems off my hands. ?
It could well be because of this fix: https://github.com/MarlinFirmware/Marlin/commit/cc3e878f90b38bcd9116c1b4e8ff31a4209299e9
Are you able to build again and see if the issues are resolved?
Hi,
I might not be the right person to help you but I think if you explained the routine you used to flash the eeprom might help. I personally just learned the way it works for my setup
Most people say use a 2 gig card flashed to fat32. Turn your power off
insert the flash card in the unit and then power on. The screen should boot but have no content for a short period of time. That is when I believe it’s flashing the firmware. It should boot up with the changed firmware.
I confirm the problem with writing to EEPROM.
Ender 3, SKR mini E3 V2.
Software downloaded from "https://marlin.crc.id.au/" both ".bin" and "custo firmware builder" files.
Defective software is date: 16/03/2021, 17/03/2021.
Returning to the software from 15/03/2021 restores full functionality.
The self-built firmware (Visual Studio Code, Marlin-bugfix-2.0.x) today also does not save the settings to EEPROM, both from the terminal and the LCD menu.
Returning to the software on 15/03/2021 returns to full functionality.
I just flashed the SKR-Mini-E3-v2-BLTouch-20210303.bin I haven't found an eeprom fault yet. I did notice that the BLTouch doesn't work or bed leveling both do nothing but that is an old build. I will look for a new fresh build tomorrow. Thanks
