Access the Marlin menu

After some tries with reboots and some tests I finally managed to get a connection so I could reset the EEPROM over the web interface.

But the rotary knob isn't working as intended, pressing the knob dosn't work with the new version.

Is there another way to test whether the press on the rotary button is getting detectet on the board?

Tested the new Version and got this:

With the rotary knob I can switch between 'Ignore' and 'Reset' but pressing the knob dosn't work.

I testet it additionally with a differnent RepRap Display and also with different cables, but it isn't working as intended.

Is it possible that I received a defective board? The only solution for the problem with sensorless homing was not to use it, now the problem with the display/rotary knob and then the EEPROM message with the new image.

EDIT: I forget to mention: I booted the older image and there is no EEPROM error.

could you try to use the newer img? PandaPi4_20210320.img or PandaPi3_20210320.img

I have checked the lcd12864 works with this img after disable the "DGUS_LCD_UI_PANDAPI",click compile-->and run

Hello Mark,

I have disabled the DGUS_LCD_UI_PANDAPI:

// PANDAPI

//#define DGUS_LCD_UI_PANDAPI

#if DISABLED(DGUS_LCD_UI_PANDAPI)

//#define ULTRA_LCD

#define REPRAP_DISCOUNT_FULL_GRAPHIC_SMART_CONTROLLER

#endif

Also this is both are disabled:

//#define NO_LCD_MENUS

//#define SLIM_LCD_MENUS

Are there any other options I should check?

I also tried it with another display, but with the same result.

Hi, have you disabled the "DGUS_LCD_UI_PANDAPI" in the Configuration.h? the default is for serial screen.
