Hi @qimao-marvin,

Can you specify the RTD revision and the S32K3xx part number?

Or can you share the whole project?

Thank you,

BR, Daniel

Because the address i try to erase and prohran in at the bank of the functiob, the 0x400000 - 0x500000 is the one bank, but even i put the code in the ram ,it caused the hardfault too,however ,if i erase at the 0x500000,the function runs well

Hi @qimao-marvin,

Can you specify the S32K3xx part number and the sector you program?

Can you share the project?

Regarding the hardfault, can you find more information about the fault?
