Unable to flash ESP32S3 prototype board #323

Hi!

Hi!
I used both
I'm pretty new to hardware, but I assume yes. For me to flash the board I have to hold down 1 button while pressing and releasing the other. Then it enters boot mode (It tells me so through UART).
Yes If I use |

I am also seeing this on the ESP32-S3-DevKitM-1 (using the idf-rust docker image, So I modified espflash and was able to connect without having to put the board in boot mode manually. diff --git a/espflash/src/connection.rs b/espflash/src/connection.rs

Ok(())Post flash/command reset still doesn't work; so requires a manual reset, either using the button or |

I just tried flashing with version So issue must be in my M1 Macbook air or Espflash version. Will test it |

Observing the same behavior with Lilygo T-QT Pro (ESP32-S3) on Ubuntu 22.10. Patch provided by @Andrew-Collins worked on 2.0.0-rc.3 (Thank you very much!) |

I see this with |

I should have a PR soon implementing the various reset strategies now used in |
|
I've implemented the retry strategies from I have not tested this much so it's possible there are still issues with it, but seems to be working on my end (not that I ever seem to have issues flashing 😁 ). If anybody here could test out this branch and let me know if it helps that'd be appreciated! |

Just bumping this. @reinismu @Andrew-Collins @senior-cpp-developer if any of you are able to confirm that #344 does or does not resolve your issues that would be very helpful. If I don't hear anything back in a couple weeks, I will likely close this issue and assume that the PR resolves the issues (as I did not experience flashing issues previously, so I'm unable to tell if this helps or not). |
|
Just realised that I wasn't passing through The ESP32-S3 uses a USB JTAG/serial controller, @senior-cpp-developer it would be interesting to see if this was your problem too. If there is no additional info, then for some reason the os/container/espflash is unable to access udev information. |

Can anyone affected by this issue check if #487 fixes the issue? |
Recently I got my hands on prototype board that uses ESP32S3 chip. It requires entering flash mode pressing buttons.
I can't manage to flash it using
espflashTho it works perfectly fine using
idf.pyHas anyone else stumbled on this?
Thanks!
p.s. It works fine when I try to flash dev board
