Free software advocates seek removal of Richard Stallman and entire FSF board

Back to our #BL602 Stack Trace ... Yep the Correct Stack Trace is indeed lurking behind our (unhelpful) Exception Stack Trace ... How shall we show the Correct Stack Trace beyond the Emptiness? 🤔

Here's how we fixed the #BL602 Exception for #LoRa Channel Activity Detection ... Always init Stack Variables! 🙏

https://github.com/lupyuen/bl_iot_sdk/blob/lorarecv/customer_app/sdk_app_lora/sdk_app_lora/demo.c#L127-L143

Answer: "radio_events" contains Undefined Fields ... Because it was allocated on the Stack! Lesson Learnt: ALWAYS Init Stack Variables! 🙏

Quiz: What's wrong with this C code? 🤔 ... I'm soooo upset I missed this simple bug 🙄

https://github.com/apache/mynewt-core/blob/master/apps/loraping/src/main.c#L215-L233

Below the #BL602 Exception Handler Stack ... Is another Stack! ... Does this Stack contain the Stack Trace that we need? 🤔

Complete #BL602 Stack Data for the Exception is here

Here are the #BL602 Stacks for the Foreground RTOS Task, Background Task and Exception Handler ... Let's see what's wrong with the Exception Stack

https://github.com/lupyuen/bl_iot_sdk/blob/lorarecv/customer_app/sdk_app_lora/sdk_app_lora/demo.c#L469-L488

Let's dump the #BL602 Stack with this function ... And figure out why our Exception Stack Trace doesn't look right
