Whether the qspi of s32g254a supports the following usage scenarios, whether the A core and the M core can reuse the qspi in time-sharing, for example, when the M core is in use, the A core reads the busy state from the qspi status register and waits for the M core to use it. Continue to operate after finishing qspi. When core A is in use, core M detects that the qspi register is busy, and waits for core A to continue operating after using qspi.
