Uploading to KC868-A6 - Vulcan - 12-21-2022
I am embarrassed to ask this and have flashed many ESP32s with far more complicated code but I am just trying to load one of the demo sketches provided by KinCony just to test my 868-A6.
I get this:

I am using "cu.usbserial 14620" drivers and they work with my ESP32's. Can anyone tell me what might be wrong?
The script is:

because of convid-19, we all stay at home, next week go to company, after tested, feedback to you.

i have tested with your code, no problem. make sure you have set correct SDA and SCL pin in your pins_arduino.h

I changed the "nodemcu-32s pins_arduino file as you instructed but still getting the same errors.
Please note that in your directory structure it's "packages/esp32/hardware/esp32/1.0.6/variants/nodemcu-32s". This is different from mine which is "packages/esp32/hardware/esp32/"2.0.6/variants/nodemcu-32s". If that helps. I am running IDE version 2.0.3. I assume I don't need to hold the flash button down when loading the sketch? Any ideas of what I am still doing wrong?
Outside of this issue......
I will admit to being confused about the many chip numbers in Espressif's products. I see that the chip onboard the HC868-A6 iS A "ESP32-WROOM-32E" and you refer to it as a "Nodemcu-32S". I have many of your processors of different models and am not always sure which one to use in IDE or platformio. By way of example, I have many "esp-wroom-32" but can never find a board manager on IDE that lists that one so I use "esp32-wroom-da". Would that be correct? I have "esp32-wroom-32" chips, which is a 38pins processor and assume different pinouts, is there also referred to as a Nodemcu?
I have previously loaded Tasmota on the HC868-A6 with an I2C display and noticed that while the relays were working from the main display, there are 7 buttons displayed (1-7) not 6. Toggling position 1 causes the I2C display to shut down. The template I am using is the HC868-A6 template. I am still learning Tasmota and am not yet sure what is happening. I check the configuration menu and it's set for GPIO 4,15 SDA on 4 and SCL on 15 and the display does work. Not sure why it's 1-7 buttons instead of 1-6, the number of relays onboard. IS that normal?
Sorry for asking more questions, just trying to learn as much as possible

hold the flash button down when loading the sketch？
--> not need, KC868-A6 have added auto download circuit on the PCB. just click "upload" button on arduino IDE.
if you really can't work , if you have "anydesk" software, we can use it remote control your pc have a look.
Nodemcu-32S is a development board name, It is completely compatible with our circuit board. sure, if you are using esp32-wroom-32, 32E, 32UE, you can all chose "Nodemcu-32S".
if you want use 6 buttons tasmota UI for KC868-A6, here we have made the tasmota firmware, deleted one button. that firmware have enabled IIC SSD1306 displayer. here is details: https://www.kincony.com/forum/showthread.php?tid=2405
