S32K312-SECUREDEBUG cannot view the SCB register

LZY — Fri, 13 Mar 2026 03:58:58 GMT

When I use S32K312-SECUREDEBUG, I am unable to use the default svd file. So I chose S32K312_M7.svd, but I was unable to view the SCB register. However, when I switch back to S32K312, it will automatically use the default SVD file, namely S32K312_M7.svd, and it can also locate the SCB register.

How to view the SCB register when using S32K312-SECUREDEBUG?

Hi @LZY

First, it is important to clarify that the S32K3 SVD files only contain register definitions for the NXP peripherals. They do not include the standard ARM Cortex‑M core registers. These core registers are provided separately in the ARMCM7.svd file.

Selecting S32K312_M7.svd does not affect Cortex‑M7 core register visibility, especially when the debugger option “Support ARM Core Registers” is disabled. In that configuration, the debugger will rely solely on the peripheral SVD file and will not try to load the ARM core register definitions, regardless of which S32K3 SVD file you select.

Hello, thank you very much for your answer. I have also found a reading method, which you can refer to.
