I tried that before, same result. tried it today and see picture for result
it looks that the SHA-256 comparison is failing
RE: KinCony ESP32-S3 Core Board ESPHome yaml for home assistant - admin - 03-01-2025
it showed finished. it work well.
RE: KinCony ESP32-S3 Core Board ESPHome yaml for home assistant - Hendrik - 03-01-2025
its not working, see the serial log after rebooting. after rebooting, and attaching a network cable, it never comes up, even i don't see it apearing in my router
even when i powered the unit, the green led on the ethernet port is on, and when i attach a network cable to it, its goiing off. then the orange one is blinking, but nothing happens
i received another kincony board yesterday, flashed it, and it works directly.
but hat one has a LAN8720 ethernet module while this one has a W5500

2: power on for your KinCony S3 board.
3: remove your finger
then board will enter bootloader, you can download now.

right step is:
1. power off S3 board.
2. hold on S2 button (not release your finger)
3. power on S3 board.
4. release your finger.
5. connect USB-C cable to your computer.
Yes, I am using the correct button.
I have many similar devices. The boards are faulty.
The spec says 9-24V not 12V specifically. 9-24V See screenshot.
my means , you can test with DC12v power . if you have tried different usb-c cable also can't work.
tell us your order number, where you buy from, we will check then feedback to you. maybe need replace ESP32-S chip.

I'm sorry to say that I can't connect to these either.
I have checked the voltages at R6 and R4 and also the S1 and S2 switches and all seem to be OK as per the schematic.
This is really frustrating. I am flash ESP32 dev board every day without issue.
What else can we check to get some firmware onto your boards. They are just not going into DFU mode.

do you have a BIN file want to download to S3 board, if YES, you can post at here, i can have a test. your board we have tested then re send to you. i don't know why you can't download by USB-C.
RE: KinCony ESP32-S3 Core Board ESPHome yaml for home assistant - Hendrik - 03-09-2025
This is my Bin file generated by esphome and flashed with esphome flasher and download tool.
compiled with esphome 2025.2
a minimal setup, only modbus is activated and a binairy sensor for the status
not able to upload a bin file, so compressed it to a zip file

There's no point in testing my bin file.
I still cannot get any of the four boards to connect to even try a bin file.
I upload to ESP32s every day without issue.
I have tried 3 different USB-C cables (all of which work with ESP32) and they do not work with your board.
I have tried every combination and sequence of power up, S1 press, S2 press, USB C connection sequence and nothing gets the boards connected.
