#Pine64 June update: new hardware and more on the way

We have a #TensorFlow Lite Model that generates a Sine Wave ... Let's use it to light up the #BL602 LED ... In a fun and interesting way!

#BL602 runs #TensorFlow Lite Model that infers "y = sin(x)" ... Output looks reasonably accurate!

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

#TensorFlow Lite runs OK on #BL602 yay! 🎉 This pre-trained TensorFlow Model is supposed to infer "y = sin(x)" ... Let's verify the output! 🥧

#TensorFlow Lite builds OK on #BL602 yay! Let's flash and run the firmware! 🤩

We set the #BL602 Global Destructor "__dso_handle" to null ... Since we're not destroying the Static TensorFlow Variables

https://github.com/lupyuen/bl_iot_sdk/blob/tflite/customer_app/sdk_app_tflite/sdk_app_tflite/demo.c#L20-L22

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" 🙄
