S32G QSPI issue

Hi NXP,

The chip I am currently using is S32G274ARDB2. I'm using both the A-core and M-core of this chip. I want them to have access to use QSPI Nor-flash.

With reference to the AN13750, I have implemented starting both A and M cores at the same time. But on this basis, I wanted M-core applications to access QSPI and ran into some problems. The current phenomenon is as follows:

Refer to AN13750, I only start M-core, and using bootloader + M-app, the QSPI driver can work normally in the M-core APP. Once the A-core is started on this basis, the QSPI Nor-flash of the M-core APP cannot be initialized normally. The M-APP QSPI Nor-flash init function crashed in the following function:

At the same time, I also checked the code of A-core, and when the ATF of A-core ran this function, it caused the M-core QSPI Nor-flash initialization failed.
