STM32 Cube Programmer Custom Loader Not Found causing error

J.Christ
Associate III

We have a custom loader from one of our boards.  It is working in STM32 Cube MX Prog V2.16 but when I launch V2.19 and try to connect to a unrelated boards I get this error:

The error is understandable because the path to the loaders is incorrect.  The issue is I never told V2.19 to use this external loader and it doesn't even show up in the list of available loaders.  It some how figured out that I have used this loader in the past (but it didn't quite figure out the correct location of the loader) and for some reason it is trying to access it.  I mess with loaders so infrequently I have no idea how to fix this issue.

The custom loader does show up in V2.16 and doesn't produce this error:

Suggestions?

Hello @J.Christ ,

What is your hardware board ? Is it a Nucleo or custom board? 

Does have any protections enabled? If yes, try disable the read protection.

Maybe you have the same issue as this thread: Solved: STM32CubeProgrammer cannot connect to MCU
