TTGO T-Display S3 won't automatically load bin file (Read 1650 times)

	I used to be able to just hit F5 in VS2022 and it would compile and upload to the TTGO. Now it fails and I have to press the boot and reset buttons in order to upload the new code. I thought it was just one chip, but I have tried several of my TTGO's and they all do the same thing. Oddly though, they work once, the first time, and after that require the boot buttons. I'm at a loss, does anybody have any ideas?

	Thanks for the report, can you let us know the answers to the below questions to help us understand the issue further: 1) Does this happen even if you use the vMicro > Uploader > Upload Last Build button? 2) Have you updated the board package since it used to work reliably? 3) When you say it works the first time, is this with a "fresh from the factory" board?

	1 - yes 2 - may have... 3 - yes I'm going to do a fresh install today and see what happens.

	I tested some more of the TTGO S3 boards that I have. It appears that I have two of them with the loading problem and others work just fine. Maybe there is something a bit off on the board. Perhaps it is time to hook up a 'scope and look at the serial signals. I also found some posts where others have had similar problems.
