STM32F0 series CRC - Default Polynomial State "Disable" not available.

[yadavpr]

Hello,

I am working with STM32F030RCTx controller. The CubeMx software is not supporting Default Polynomial State: "Disable". 

I wanted to use a custom CRC polynomial and need help initiating the same. Here is a screenshot for reference:

Thanks.

The STM32F030 does not have the capability of using a custom CRC polynomial.

Other chips in the STM32F0 family do, but not this one.

 

If you want a polynomial other than that, you'll need to do it in software.
