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
