Hi,

I am using the ST-LINK_CLI.exe utility with the ST-LINK/V2 in a production test fixture to program a STM32F107.  Everything seems to work fine but if I issue ''ST-LINK_CLI.exe -ME'' to mass erase it it reports succesfull but then the next time I try and reprogram it with:

ST-LINK_CLI.exe -c SWD -p ''\filename.bin'' -Rst -Run

 

I get this message:

''

The Core is locked up!

''

If I then use the  STM32 ST-LINK Utility.exe it programs fine.

How do I unlock the core?

How do I erase without locking the core?

Thanks

Mat
