Non-standard UART on MKS-DLC32

[bullestock]

Hi,

I am using the ESP32 driver on a Makerbase DLC32. Compiling with default options works fine and lets me communicate with the board via the USB port.
Now I would like to instead use two pins on the extension connector as UART pins. I tried this in my_machine.h - and it works to the extent that I can no longer communicate via USB, but I cannot get it to work on the UART pins either:

#define SERIAL1_PORT
#define SERIAL_STREAM 1
#define UART1_RX_PIN            GPIO_NUM_33
#define UART1_TX_PIN            GPIO_NUM_26

What am I doing wrong?

What am I doing wrong?

Using pins that are also assigned to auxiliary ports?

Thank you, that was indeed the problem.

I have now #undef'ed the aux port definitions in mks_dlc32_2_0_map.h - AFAICT it cannot be done in my_machine.h.
