NodeMCU ESP-32s USB Firmware Upload for LUA: Serial Port Not Detected, ESP8266 Log

Good day,
I have the above mentioned board. The only info I have found for uploading software is a schematic for connecting via 5V/3V3 converter + using NodeMCU Firmware programmer(using batch(nodemcu_integrer from github).

Can't this be done via the USB port on the board?
I set it in download mode(reset+enable buttons from the board) - it works, because I can see the status in the serial port monitor in ArduinoIDE.
Settings: 16MB, 115200, 40MHz, DIO.

In the log there is info:
Note:Serial port connected.
Note:Begin find ESP8266.

Trying again to set in download mode does not help.

Anyone, anything?

Perhaps the article Uploading firmware to the ESP8266 will prove somewhat helpful....

Using python and esptool, I cleaned and uploaded nodemcu_integer_0.9.6-dev_20150704.bin.

Using netbean I tried to build Esplorer .
Instruction .
In netbean
1)I select jdk 1.8,
2) I point to rsyntaxtextarea 2.5.6.jar
3) and add the library jSSC . Although I don't know if I'm doing it right(I create a new one called jssc and point to the jssc.jar file

The esplorer.jar file builds, I find it on disk and fire it up(run in netbean doesn't work). I refresh the ports, open com4(my board) and the program closes . Some error files are created. Upload?
The same happens for the finished esplorer(esplorer.zip) from this page .
Isn't there some other programme that works?
It looks like the one from your tutorial only works under Linux(no instructions on how to run on windows).
