STM32U545 External Loader "Init Function Fail"

GiBi_01

I have an External Loader Project made for STM32G0/G4/L4.

I ported it to STM32U5: all the functions work fine when debugged from STM32CubeIDE (so the connections are ok). With the STM32CubeProgrammer the .stldr file is recognized but the Read/Write/SectoreErase operations fails due to "Init Function fail". 

Any suggestion will be appreciated!

Hello @GiBi_01 ,

Which CubeProgrammer version used ?

Make sure to use the latest STM32CubeProgrammer release v2.17.0.

If the problem persists, please attach your option bytes configuration.
