Hi, Daniel

According to your reply, I uncheck "Set breakpoint at" in the "Runtime options" subsection. But S32DS still indicates an error.

Before S32DS reported the issue "Can not access memory...", I modified the memory section of the application's linker file according to AN12218, S32K1xx Bootloader.

Applicaton's memory section is shown below.

The application, downloaded by bootloader using UART, didn't work. So, I recovered the memory section, downloaded again by OpenSDA, and then, the issue "Can not access memory..." occured.

Hi dony,

Hard to say. There could a problem in the bootloader.

Where is the bootloader located in the flash and how do you jump at the application?

What do you see in the debugger's console before the error message?

Have you tried loading an S32K144 example instead?

Do you have another debugger besides OpenSDA?

Thanks,

BR, Daniel

Hi, Daniel

Today, I reinstall the S32DS, and now everything is OK.

Anyway, thanks for your help.
