+// Reference implementation of the DebugLog() function that's required for a
+// platform to support the TensorFlow Lite for Microcontrollers library. This is
+// the only function that's absolutely required to be available on a target
+// device, since it's used for communicating test results back to the host so
+// that we can verify the implementation is working correctly.
+// It's designed to be as easy as possible to supply an implementation though.
+// On platforms that have a POSIX stack or C library, it can be written as a
+// single call to `fprintf(stderr, "%s", s)` to output a string to the error
+// stream of the console, but if there's no OS or C library available, there's
+// almost always an equivalent way to write out a string to some serial
+// interface that can be used instead. For example on Arm M-series MCUs, calling
+// the `bkpt #0xAB` assembler instruction will output the string in r1 to
+// whatever debug serial connection is available. If you're running mbed, you
+// can do the same by creating `Serial pc(USBTX, USBRX)` and then calling
+// `pc.printf("%s", s)`.
+// To add an equivalent function for your own platform, create your own
+// implementation file, and place it in a subfolder with named after the OS
+// you're targeting. For example, see the Cortex M bare metal version in
+// tensorflow/lite/micro/bluepill/debug_log.cc or the mbed one on
+// tensorflow/lite/micro/mbed/debug_log.cc.
