Hello, I recently bought two ESP8266 ESP-12Es, bought adapters for them and they came. I didn't buy a programmer because I have a Tiny and I've read some tutorials on various forums that it can handle it. But the problem is that in my little one in the file "/boot/cmdline.txt" there was no line with "ttyAMA0". The contents of the file /boot/cmdline.txt:
 .
So, just to be sure, I removed "console=serial0,115200", later I found out that you have to deactivate some services with commands:
 .
  .
 .
I have connected (Pi->ESP):
1->VCC and CH_PC
9->GND and GPIO0
8->RXD
10->TXD
I wanted to upload the latest version of nodeMCU via "esptool.py" and I only get "Connecting..." all the time anyway.
Command:
 .
When connecting the ESP to the power supply the blue light flashes for a while, I don't know what I'm doing wrong, let me know if I've accidentally damaged something and I'd appreciate your help
Best regards and happy holidays,
Tom
