Hello Kui Wu,

Do you mean the internal flash and RAM? If this is the case you can change to this moving the VTOR register to the starting point in flash or RAM. Also, the S32DS always configures two debug sessions, one for RAM and the other for flash.

Hello 814420552@qq.com‌,

Only switching between debug session is enough to change between SRAM and flash, you don't need to change any hardware to do this. You can confirm this if you use the SRAM debug session and power-on the board.
