Qflash - GetDAInfo failed Errcode 1

Technical Subjects Upgrade/Debug

I’m trying to flash/upgrade a BC66 Chip via Qflash. Unfortunately, I receive the error message:

GETDAINFO failed Errcode 1

Any pointers to what’s going on?

I upgraded ch340 drivers. Changed USB cables.
No change.

Would be great if someone solved this.
