Solved: I'm unable to get work my nucleo-L053R08 anymore. Flash operation stops at 93%. What can I do to resume operation.

Only a couple of days ago, I startet to work with STM32cubeIDE. I'm new with STM32 and also new with the cubeIDE, but I do need this in future for product development. I'm using a nucleo-L053R8 board.

After starting a very simple test script to let blink a LED, I downloaded this a few times onto the board, using F11(Debug), which worked fine a few times.

At any time, cubeIDE crashed an had to be killed by using task-manager. From that time, I'm stepping from one problem into the next, not being able to get anything work again.

Currently, the status bar stops at 93% when downloading the software:

Probably after some timeout I get the following error message:

Using google, did not show any usefull result to. There a lot of hits, but everything seems not to be applicable to my configuration.

Currently I'm realy frustrated with the IDE, as it is too complex for a beginner to understand where to start searching for a solution.

BTW: What I did so far: Uninstalling and reinstalling cubeIDE with no result. Starting a new project, which just resulted in differen error messages. Upgrading the ST-Link firmware on the board, with also no result.

Any idea, what I can do to get things work as intended?

Try to dowload and install ST Link Utility, and yry to connect to the target from there, maybe also setting "Connect under reset" there.

Thanks a lot! That worked immediately and is a good work around.

However ist getting even more weird! There was one small project I was able to upload from stm32cubeIDE, but only until I changed the code in main.c, forcing a new built of the project. From that time, I was no longer able to upload the code, it also stops at 93% now. Maybe anyone has an idea, what could be misconfigured?

To me it looks like, that stm32cubeIDE ist anything else than mature and very buggy. I do not have any big projects yet, I just started my first blinking-LED-hello-world programs, facing one problem after another ... >:(

Problem is solved by updating to the latest Java 64bit JRE!
