Debug Authentication on STM32U585 with RDP1 and TZEN Enabled

Hello,

I am using an STM32U585 (evaluation board B-U585I-IOT02A), and I would like to enable debugging via Debug Authentication while the device is in RDP Level 1 and with TrustZone (TZEN) activated.

I have looked for documentation or examples but have not found any resources specifically covering this configuration.

Do you have any references or guides that explain the necessary steps (e.g., STM32_Programmer_CLI commands) to set up Debug Authentication in this context?

Thank you in advance for your help.

Best regards,
Paul Goulpié

Hello @paulgoulpie ,

This Debug Authentication is a recent mechanism on STM32 and is only available on STM32H5 and STM32H7RS.

The STM32U5 supports regression with password only.

Best regards
