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

Several people have complained about similar issues recently.

I'd have my firmware write it's own OTP area as its use tends to be device specific.
