I’ve been using it without any issues until recently, but suddenly, I can no longer write the image.
The USB connection is confirmed to be working, and the DIP switch is set to Serial Download Mode.
What could be the reason it’s not working anymore?
What's even more strange is that I couldn’t figure out what was wrong, so I tested with another board — and the write was successful.
Then I reconnected the original problematic board, and this time the writing succeeded as well.
What could be the cause of this behavior?
Is there something unstable in the current software?
If it fails intermittently like this, what should I do to recover from the failure?
Below is the Log from the Tool window.
