Hi,all
i use S32K312 MCU, when code run calculate double data, trigger exception, not always occur.
when exception occured,
BFSR register Value: 04: indicate it is a IMPRECISERR BUS error
ABSFR register Value: 0x0208: indicate it is AXIM bus error, error type is SLVERR
because IMPRECISERR BUS error is async error, so when exception occur, the current PC not equal to trigger issue PC. S32K312 use Cortex-M7 which not provide interface to close write buffer to let IMPRECISERR BUS error change to PRECISERR BUS error.
could you pls Provide some analytical directions， thanks
