[S9KEAZN8] MCU sometimes fails to boot up.

Hello,

Has anyone encountered an issue where an MCU is powered with 3.3V but fails to operate?

I am using the Components Library in KDS to create a program that pulls GPIO high upon boot-up, but sometimes the GPIO does not get pulled high during power-up.

Does anyone know why this might be happening?

 

Did I make any mistakes in the circuit design?

Hi @johns_chuang 

We recommend to use Design studio for arm instead of the kinetis design studio to avoid the old IDE reability.

Best Regards, Miguel.

Hi Miguel

Where can I find the SDK for KEA8?

Can Components Library be used to design KEA8 in S32 Design Studio (S32DS)?
