Customer:

I’m getting a linker error when trying to create a WiFi server on my Inkplate 10. The compiler reports:

This worked last week. The error occurs at this line:

WiFiServer server(80);

My sketch includes:

#if !defined(ARDUINO_INKPLATE10) && !defined(ARDUINO_INKPLATE10V2)
#error "Wrong board selection for this example, please select e-radionica Inkplate10 or Soldered Inkplate10 in the boards menu."
#endif

#include "Inkplate.h"
#include
#include

#define ssid "Inkplate 10"
#define pass "Soldered"

Inkplate display(INKPLATE_3BIT);
WiFiServer server(80);

#define MAX_IMAGE_SIZE

IPAddress serverIP;
char ;
int inputPos = 0;
char breakChar = '|';
SdFile file;
char *fileName = "image.png";

Soldered Support:

Did you change anything in your sketch since last week? The library was last updated three weeks ago, so there shouldn’t be any difference in the main example. Try running the WiFi server example straight from the library without any code modifications - see if that works and what the differences are between your sketch and that one.

Do you have any large data structures like images or large arrays in your sketch? I have seen this error happen with the Google Calendar example - where the ‘entries’ array ends up being too large for the DRAM.

If you have any large data structures like images - I would suggest moving them to PSRAM using ps_malloc.

You were right. I had defined an array that was too large.
