STM32L4 OTP flash programming via STLINK

Hi,

I am trying to program the OTP flash on a L4 via STLink V2, however, it gives the error: 

The elf loader file is not accessible.
Writing 0x00000006 at 0x1FFF73F8...Error!

I have tried using the CLI with the command   ST-LINK_CLI.exe -w32 0x1fff73f8 6  , and by using the ST-LINK GUI, which gives the same error.

Any ideas on how to fix this issue?

Thanks, Matt
