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  distributed from GitHub at https://github.com/renesas/ra-fsp-examples. 

EPs are simple projects that show how a given RA peripheral can be setup and used.  EPs are listed based on officially available Renesas HW kits.  Some of these are  Evaluation Kits (EKs), Fast Prototyping Boards (FPBs), and Motor Control Kits (MCKs).   

APs are more involved projects that may utilize several peripheral to provide a solution.  For example, cloud connectivity or low power applications for specific Renesas HW kits.    

You can download EP and AP bundes in zip form from the GitHub site in Releases page.  This will allow you to get all EPs and APs.  However, this is a very large file and you may be interested in a one EP on a given kit.  How do you downlaod only the EP or AP you want or need?

You do with GitZip Web extension.  With GitZip extension:

1. Select the files or the folders you want
2. Click on Download
3. Your selections will be in a zip file

  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.
