Hello, encrypted Auric CPUs are used in car ECUs. Is it possible to reprogram these CPUs using a Cyclone device?

Hi there,

Can you please provide the complete part number of the microcontroller that you want to reprogram?

Hi,

We support flashing programming of the Infineon AURIX TC29x. By encryption, are you referring to the debug password protection in the UCB. Please clarify. I don't have any experience with how the UCB and debug protection works on this family of devices so I will forward your question to my colleague who is more knowledgeable on that.

Regards,

Yes, the UCB partition is encrypted and we don't know the password. I want to delete the UCB partition, restore it to its raw state, and reprogram it.
