Unable to flash my ESP32

OSchell · May 13, 2024, 5:43pm

Heyo !
I have to admit, it’s my first time with HA. I have a RPI 4B with the HA OS and a ESP32 that I will use to connect an ENS160 through ESPHome.
Tried all afternoon and I’m hitting a roadblock with this error message always appearing whatever I do… (the […] are for the sake of shortening the error message.

Notes:

I’ve already tried removing build files and remove/reinstalling ESPHome (at some point, it helped)

Do you have any idea or hints has to what I can do to progress ?

You should show the code you are trying to use in esphome.

peterxian · May 14, 2024, 7:05am

Have you attempted to “Clean build files”? Esphome is failing to compile your firmware image, and cleaning the build files often helps.

OSchell · May 14, 2024, 11:09am

Updated the post in this regard, thanks for the suggestion !

OSchell · May 14, 2024, 11:18am

I did but to not results… Updated the post to include this information

Have you tried just flashing with the minimal code to see it that working?
I see esp32c3 is mentioned in the log. Is it a C3?

Well, I resolved the issue, but not the way I wanted:
When I left yesterday, I shuft the power and stored it. When, this afternoon, I powered it on and started looking, everything went well except for loose connector that kept the ESP32 from seing the sensor. After a short correction of the problem, It installed correctly and I let the ESN160 warm up (1h). After some time, I realized that HA OS had crash yet again(Error 500 on the brower) so I shut it off. After rebboting, I started seeing an other strange error (again) with some files. And that’s when it hit me: “Maybe files are getting corrupt… They would go well with me shutting it off be shutting down the power… Does it exist a way to shut it of cleanly, via the interface ?” After a quick google search, it seems like yeah, it does ^^.
A clean install of HA OS (the corruption broke the installation of ESPHome) later, everything is going well* !

I don’t know if the error 500 has anything to do with that (we will see)

TL;DR: I had problem with corrupt files because I was cutting the power source to power it power it off…

* I’m struggling to get Home Assistant to “accept the sensor” but I don’t kown if it’s because of the warm-up time of one hour of the sensor…
