NXP i.MX RT register definitions

[tm123]

Hi,

So I got a J-Link recently, managed to follow this tutorial;

https://visualgdb.com/tutorials/arm/imxrt/

and it all worked fine. However I am trying to look at registers and tried to give VisualGDB the .XML file that NXP ships that describes all the register but it doesn’t like it.

Then I saw this tutorial;

https://visualgdb.com/documentation/hwregs/

And it seems the NXP layout doesn’t match the one VisualGDB wants, is there any way to convert over or a definition file anywhere? Or are my only chances to manually create the definitions myself?

Thanks for confirming your license, we have linked it to your account.

Indeed, VisualGDB internally uses its own format to define the registers. However, it also supports the SVD file format used for modern ARM devices. Normally, if the register file was not automatically imported, you can click the “locate” link in the Hardware Registers window and point VisualGDB to the SVD file, and it will get automatically converted into the VisualGDB format.

The logic for importing the SVD files is open-source and is available here: https://github.com/sysprogs/BSPTools/blob/master/libraries/BSPGenerationTools/SVDParser.cs

If this doesn’t help, please upload the SDK that did not get properly imported to a file sharing service (e.g. DropBox) and post a link there so that we can investigate it further.

The file originally ships as a .xml extension and it seems renaming the file to the .svd extension fixed it. It loaded in properly after feeding it in. Awesome, glad it’s supported.

Good to know it works. BTW, if the file uses the SVD format, it should have been imported automatically together with the rest of the SDK. Feel free to share a link to the SDK and we will make sure it gets handled fully automatically next time.

The file was under devices>MIMXRT1021, it’s just labelled “MIMXRT1021.xml”

If it’s any help this is the actual error;

Thanks, we have updated VisualGDB to fix the issue: VisualGDB-5.5.8.3753.msi
