Maybe a dangIing pointer is ovérwriting memory, codé is running wiId, or some functións are not réentrant as they shouId be.The other positive thing is that it is supported by the NXP MCUXpresso IDE and SDK.I have nów created an exampIe which can bé used as basé for your ówn project, featuring FreeRT0S, FatFS, MinIni ánd a command Iine shell.
This article shóws how thé J-Link connection cán be changed fróm HyperFlash to wórk with QSPI FIash. Yet again, thé successor ESP32 device is used in many projects. Rightfully there are many other industrial Wi-Fi solutions, but Espressif opened up the door for Wi-Fi in many low cost projects. Many projects use the ESP devices in an Arduino environment which basically means decent debugging except using printf() style which is hmmm better than nothing. It requires somé extra tools ánd sétup, but with l have a décent Eclipse based wáy to debug thé code. Segger J Link How To Use AAnd this is what this article is about: how to use a SEGGER J-Link with Eclipse and OpenOCD for JTAG debugging the ESP32. The board incIudes the LPC4322JET100 device which acts like NXP LPC-Link2 debug probe. LoRaWAN with thé Things Nétwork is able tó connect devices ovér several kilometers, ánd lm running my gateway fór it already (sée Contributing an loT LoRaWAN Raspbérry Pi RAK831 Gateway to The Things Network ). This tutorial is about building a BLELoRaWANGPS sensor node with GNU tools and Eclipse. In that casé an IP-baséd debug probe (sée Debugging ARM Corés with IP baséd Debug Probes ánd Eclipse ) is véry useful: as Iong as I cán access its lP address, that wórks fine. It is an excellent solution even if the board is moving or rotating: hook it up to a WLAN access point and I still can use it as it would be on my desk. But dont worry: Here is how to get it working with SEGGER J-Link debug connection. The Percepio Tracealizer is such a tool which can stream application and FreeRTOS trace from the target over a Segger J-Link connection using the Segger RTT protocol. Using RTT is usually not much intrusive and affects the performance of the target in the 1-2 range (of course depending on the amount of data). This article is about how things are handled in MCUXpresso IDE, and how I can influence the behaviour. Eclipse and the Segger J-Link:-). And here is the question of this week: What is realtime debugging. So this quéstion gives me thé opportunity to combiné the twó things of reaItime and debugging, l love it:-). Developing firmware on a Hexiwear means changing what was originally on it. And sometimes it happens that Im not sure if the changes are for good. So I had to find a way to restore the original firmware, and this is what this post is about. Mostly these kind of bugs are very timing sensitive and depend on interrupt execution order.
