quick tips to help you with RA MCUs, its software, tools, and boards.  If you have any tips, please let us know and we will include them here.  

RA Tips and Tricks

Here are a few tips and tricks for you to help with your development.  We also have the frequently asked RA questions and answers to them.  Each topic is provided in their own page for easy navigation and maintenance.  Below is a list of available items.  

Multiple Pin Configurations

FSP allows a user to create multiple pin configurations in the same project.  This tip shows you how to do it. 

Multiple Pin Configurations

Debugger Connectivity with ID Code Protection

ID code protection allows or prohibits programming and on-chip debugging. The device checks the ID code provided by the debugger against an ID code stored in a special flash memory.  This article describes where this special flash memory is, how to set it using FSP configurator, big or little endian considerations, and may other aspects of ID code protection for non-TrustZone RA devices.

Debugger Connectivity with TrustZone Devices

TrustZone RA devices require specific hardware connections for debugging.  Further, these devices must be in a correct Device Lifecycle Management (DLM) state to access Secure (S) Non-Secure (NS) and Non-Secure Callable (NSC) memory regions at different stages of a development process.  Read more about it at below link.

An Easy Way to Download EP and AP Projects

There are several RA Example Projects (EPs) and Application Projects (APs)  distributed from GitHub.  They are distributed based on the officially supported RA boards.  However, if you are only interested in EP for RA8D1 ADC module, you do not need to download all EPs for that board.  Here is how.
