IMXRT105x hardware register defs

[mmilo]

NXP already provides a .xml with the hardware register definitions with their BSP. The format is not the same as required by VisualGDB (http://visualgdb.com/documentation/hwregs).

Is there any chance that I could get some help converting the file? Maybe you already have some in-house tools that could ease the process?
I’m guessing it’s the same for all NXP products? It would really be awesome if we could use those hardware register definitions, just like you already added support for their BSP’s.

Hi,

This looks like a regular SVD file that should be already supported by VisualGDB. Simply select it when clicking on the “Locate SVD file” link in the Hardware Registers window and VisualGDB will automatically convert it to its format.

Alternatively, you can use the converter from our BSPTools repository that is equivalent to the converter used by VisualGDB.

Unfortunately visualGDB fails when I try to import the .xml with the hardware definitions from NXP.

Thanks for letting us know, however unfortunately it’s hard to suggest anything specific without knowing more details. If you could describe exactly how you were importing them and what you observed (and ideally, share the entire file you tried importing), we should be able to suggest a workaround or release a hotfix for it.

I’ve attached the hardware definition file generated by the newest version of the NXP SDK for the IMXRT1052 (zipped because it’s 8MB).

I get the following error when I open the Hardware Registers windows and try to “Import register from an SVD file or a VisualGDB resiger definition file”

VisualGDB version: 5.4.112.3242

When I try to add the file in the VisualGDB project properties -> Embedded Project -> Peripheral register definitions, then the Hardware registers windows says they are still missing when trying to open it while debugging.

I assume that the registers definitions .xml generated by NXP is just too different from the VisualGDB standard for it to work. Hopefully you guys can make a fix, as I guess it would make it work for all NXP devices, not just the IMXRT1052.

Thanks for the update. Looks like VisualGDB tries to load it as a VisualGDB-specific XML file instead of using the SVD loading logic.

Please try changing the file extension to .svd and importing it again.

Works perfectly, thanks a lot!
