Hello, we develop a project with tms570ls3137 Hercules MCU, this MCU is dual core, but we use only one core. Is it possible to use a single core, and if it possible, is this situation affects my system?

I want to know this information for aviation standard that is DO 178-C, so I need a document for this to prove the answer. Are there any mention on userguide or reference manual?

Hi,

That is not possible. Both cores are permanently in lockstep by design with a compare module constantly comparing between them as a critical safety mechanism for this processor architecture.

Thank you Charles,

Then I have to use both CPU that you said. What if one CPU malfunctions, at that time on the other CPU doesn't work, am I right ?

The other thing is are there any document that has the answer this question?

When one CPU fails, the CCM (CPU Compare Module) will detect and asserts a compare error. Please refer to the CCM module in the TRM for details.
