How to show the peripheral registers at debug in MCUXpresso for VSC

KNagai-Private — Wed, 11 Mar 2026 06:31:56 GMT

Hello team,

I'm using MCUXpresso for VSC and FRDM-MCXA153.

SDK is SDK_25_12_00_FRDM-MCXA153 and using the sample code "hello_world".

Could you tell me how to show the peripheral registers at debug session, please?

MCUXpresso IDE can show the peripheral registers as below.

I want to do same thing on the MCUXpresso for VSC.

Best regards,

Toshi

Hello @KNagai-Private ,

Thanks for your post. It seems a known issue.

Please try the method in Solved: How use SVD file in MCUXpresso for VSCode - NXP Community.

You can add the MCXA153.xml path into the launch.json.

And then debug it again and open the "PERIPHERALS" view of the bottom panel.

Hope it helps.

Celeste

Hi @Celeste_Liu ,

Thank you for your advice.

I understand, but I could not find the MCXA153_cm33_core0.xml in my SDK.

Could you show me where the MCXA153_cm33_core0.xml located, please?

Best regards,

Toshi

Hello @KNagai-Private ,

Sorry, not MCXA153_cm33_core0.xml.

Please refer to the attached MCXA153.xml instead.

In addition, you can find MCU product SVD file via GitHub - nxp-mcuxpresso/mcux-soc-svd: MCUXpresso SDK SoC SVDs · GitHub

I have tested the attached MCXA153.xml, and it works properly.
Please see the attached screenshot.
