We disable Thread-Safe Initialisation by setting "-fno-threadsafe-statics" ... This fixes the Missing Functions "__cxa_guard_acquire" and "__cxa_guard_release" in #BL602 TensorFlow

https://github.com/lupyuen/bl_iot_sdk/blob/tflite/customer_app/sdk_app_tflite/sdk_app_tflite/bouffalo.mk#L37-L41

Aha "CPPFLAGS" should be defined in #BL602 "bouffalo.mk" ... Not "Makefile" 🙄

https://github.com/lupyuen/bl_iot_sdk/blob/tflite/customer_app/sdk_app_tflite/sdk_app_tflite/bouffalo.mk#L28-L41

Just realised that "CPPFLAGS" works for building #BL602 C++ Libraries, but not for BL602 C++ Apps ... Dang

https://github.com/lupyuen/bl_iot_sdk/blob/tflite/customer_app/sdk_app_tflite/Makefile#L12-L20

This #BL604 LCD looks complicated 🤔

Final few Missing Functions for TensorFlow Lite on #BL602 ... Let's find out what they are

https://github.com/lupyuen/bl_iot_sdk/tree/tflite/customer_app/sdk_app_tflite

Setting this flag will tell TensorFlow Lite to use Static Memory (instead of Heap Memory) on #BL602 ... Neat!

https://github.com/lupyuen/tflite-bl602/blob/main/bouffalo.mk#L46-L49

Our #BL602 Build of TensorFlow Lite calls "new" and "delete" to Allocate and Deallocate C++ Objects in Heap Memory ... But it's supposed to use Static Memory, not Heap Memory ... Let's find out why

https://github.com/lupyuen/bl_iot_sdk/tree/tflite/customer_app/sdk_app_tflite

Source Folders for TensorFlow Lite are defined in the #BL602 Makefiles "bouffalo.mk" and "component.mk"

Our #BL602 Build of TensorFlow Lite ... Fixing a few more missing C++ Functions

https://github.com/lupyuen/bl_iot_sdk/tree/tflite/customer_app/sdk_app_tflite

#BL602 TensorFlow Lite also needs the "ruy" library ... For matrix multiplication

https://github.com/lupyuen/tflite-bl602/blob/main/bouffalo.mk#L71-L82

#BL602 Makefile for TensorFlow Lite needs this ... To fix the Math build errors

https://github.com/lupyuen/tflite-bl602/blob/main/bouffalo.mk#L21-L27

Our #BL602 TensorFlow Build hitting some Math errors ... Let's fix them

https://github.com/lupyuen/bl_iot_sdk/tree/tflite/customer_app/sdk_app_tflite

TensorFlow Lite Makefile looks complicated ... Let's download "gemmlowp" the simple way on #BL602

https://github.com/lupyuen/tflite-bl602/blob/main/bouffalo.mk#L52-L69

TensorFlow Lite downloads dependencies in an unusual way ... Let's so the same in our #BL602 Makefile

https://github.com/lupyuen/tflite-bl602/blob/main/tensorflow/lite/micro/tools/make/Makefile#L514-L517

Our #BL602 TensorFlow Build has lotsa missing functions ... Let's fix the build

TensorFlow Lite app exports the functions "setup" and "loop" (So cute!) ... Let's add them to #BL602 Command-Line Interface

https://github.com/lupyuen/bl_iot_sdk/blob/tflite/customer_app/sdk_app_tflite/sdk_app_tflite/demo.c

Fixed the #BL602 Makefile to install FlatBuffers ... For compiling TensorFlow Lite

https://github.com/lupyuen/tflite-bl602/blob/main/bouffalo.mk#L16-L56

Missing FlatBuffers when building TensorFlow Lite for #BL602 ... Let's fix this
