You need set SERIAL_PORT 1 when you use the latest version marlin firmware.
OK. And SERIAL_PORT_2 ? Should it be commented?
You need disable SERIAL_PORT_2. I will update our Wiki.
I will close this issues temporarily
Mismo problema con marlín 2.0.8.2. Err0r con serial port -1. Cambio a serial port 1 y baudrate 250000 y compila pero la tft35 no se comunica con la impresora.
Hi, I downloaded Marlin bugfix-2.0.x from official site. I used example Configuration.h and Configuration_adv.h and set up parameters for my Ender-3, BLTouch, etc. I configured #define SERIAL_PORT -1 as indicated on this site's Wiki. I also set #define MOTHERBOARD BOARD_MKS_ROBIN_E3D_V1_1. When I compiled I got error "SERIAL_PORT is set to -1, but the MOTHERBOARD has no native USB support" . As it turned out this error is generated by this directive on the board definition in standard Marlin #define BOARD_NO_NATIVE_USB. So in new Marlin you cannot set serial port to -1 for Robin E3 boards. What should I do to compile Marlin and to have the USB communications working correctly?
