After pulling GPIO0 to ground, pushing the res key and releasing GPIO0 again, the download of code is perfectly working. But just a few minutes ago i found i very interesting problem: After loading the Code the screen stays dark, i can see the connect/disconnect in my syslog. Yesterday evening i stopped working with this board and today, just before, i connected the board to a USB power Supply ... and the code was running perfectly. I disconnected again and reconnected to my PC, it was working again. Then I disconnected once more and reconnected again, and now nothing happens anymore? Must i wait until tomorrow to have the code running again? Has anybody seen this problem also?
Does anybody know exactly which board to select and/or build flags to use in platformio for the WT32 SC01 plus?

@sukesh-ak

Thanks for the link, but i do not have an upload problem, as i fixed it as described in my last comment in the same manner as in the discussion in your link.
My problem is that the sketch does not start after uploading, even after powering down and up again. I must wait ~10 minutes (maybe a little bit less ) before the sketch can run.

That does not sound like a hardware issue :)

I didn't experienced this using pio

This worked great. I was about to send board back. Thank you.
