OpenOCD Fails to Identify STM32U3 Device

[vijayrakesh13]

Hi team,

I'm currently trying to debug an STM32U3 series microcontroller using OpenOCD. Since OpenOCD does not yet include an official configuration file for the STM32U3 family, I used the config file generated by STM32CubeMX.

However, when I attempt to connect to the target, I receive the following errors:

CPU in Non-Secure state [stm32u3.cpu] halted due to debug-request, current mode: Thread xPSR: 0x69000000 pc: 0x0800066c msp: 0x2002fff8 Error: Failed to read memory at 0x40015800 Warn : Cannot identify target as an STM32C0/G0/G4/L4/L4+/L5/U0/U5/WB/WL family device. Error: auto_probe failed

Details:
MCU: NUCLEO STM32U385RG-Q
Config: Using the .cfg file auto-generated by STM32CubeMX

It seems the STM32U3 series is not recognised. Is there any ongoing work or guidance on adding support for the STM32U3 series to OpenOCD?

Thanks in advance!
