Product:S32K144 EVB

IDE:IAR for ARM 7.60.2


①:Where the hart fault occurred。The variable flashAddress=0x78400

②:Based on CFSR and HFSR,I found that MCU accessed a invalid address。

③:Then I watched memory range 0x78400--0x7840f,  the result was "-- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --"。So it indicated that the memory is not accessible。

Can someone tell me why the memory is not  accessible please?

Best regards!
