Dead Board? - grs56 - 09-22-2023
Hi,
I have a KC868-A8.
I Flashed it fine four days ago using ESP Home on windows 11. The board is connected to a regulated switched-mode 12v supply. I had started to program up a script to use as an aquaponics controller. I had the following connected:
One dry contact on the first input
One TDS sensor on A1 (+4v)
One DS18B20 on S1
All was working well. I left the board running overnight.
Came back this morning and noticed that it wasn't showing up in Home Assistant or responding to its IP address.
Power was still OK everywhere.
I have attempted to reflash using esphome webtools and using ESP flasher and your own
tool from here: ESP Module Flash Download Tools - Smart Home Automation | KinCony
I have rebooted and reinstalled the com port.
I have tried from my mac.
The Serial port is showing up on USB connection on both the mac and PC.
I have tried with a different USB cable.
I have confirmed I am able to flash other esp32 chips from the PC with no problem.
I have tried using the s1 and s1 as boot buttons.
My assumption is that the board is dead unless you have other advice?
----
config for reference:
I had yet to attach the Ph probe as I was building a voltage divider this morning. Also the Ultrasonic sensor requires some extra files for the build and i had yet to but those in the right place.

RE: Dead Board? - admin - 09-22-2023
what problem now? can't download firmware? what power supply you have used? dc12v xxA?
RE: Dead Board? - grs56 - 09-22-2023
the esp32 appears to be 'dead'
it was running fine using esphome. Now it is not responding and I am not able to flash / download any firmware.
The power supply is 150w PC power supply so 12v ~ 10A. I have a bench supply also 12v 6a.
The board shows power but I cannot flash.
The device shows up as a valid COM port but the flashing software is not able to make a connection to initialise the device

can you change another USB-C cable? not use USB hub. or change another USB port of your computer.

please read my original message
i have tried:
different USB cables
different ports
different computers
reinstalling the com port
I have verified that the cable and PC works by programming a different esp32 and and esp8266
If it worked and now it doesn't. Unless you have another suggestion to force reset / enable Flash i have to assume this is broken?
I received the board two days ago and it's been worked on on an antistatic workbench. I think there must be a defect for it to fail so soon?
I can post a video if helpful?
