I'm using 2.0.4 with Win 11 and a Teensy 4.1. I'm am beating my head against the wall over this compiler error message:
c:/users/user/appdata/local/arduino15/packages/teensy/tools/teensy-compile/5.4.1/arm/bin/../lib/gcc/arm-none-eabi/5.4.1/../../../../arm-none-eabi/lib/armv7e-m/fpu/fpv5-d16\libc.a(lib_a-openr.o): In function `_open_r':
openr.c.text._open_r+0x12): undefined reference to `_open'
collect2.exe: error: ld returned 1 exit status
exit status 1
Compilation error: exit status 1
I'm trying to access the onboard SD card and I know it's good as the Card Info program works. I have also run some other example programs that read a BMP file from the SD card, and those work. I can read the bmp image with one of the examples sketches on a 2.8" ILI9431 display (SPI), but I can't "manipulate" it. I'm trying to read that same BMP image for display/manipulation using the ILI9431_t3 library.
Any ideas would be greatly appreciated.
