On SPI operation, What is different for connecting S32DS and not connecting S32DS?

[kbj]

Hello,

I develop MCU with S32K144 and S32DS(SDK3.0.0).

On SPI operation, S32K144 is SPI slave.

After Power up, Master transfer the message. But S32K144 do not work .

But After Started by S32DS(S32DS debug mode), Master transfer the meaange. S32K144 receive the message.

What is different for with S32DS and without S32DS?

Why this situation is occred?

What did I do wrong?

Please let me know.

Best regards,

Byungju.

Hello,

You could try to attach the debugger to the running MCU without reset, halt the execution and check all the SPI registers, clock configuration etc.
