• bricked ESP8266 ? any command errors with "Failed to write to target RAM (result was 0107)"

  Thank You for Your good answer and advices, Hungryforcodes!

  Here in Finland we have (AFAIK) only one word which starts as "Esp" -string, it is "Espanja" which means Spain. So, my brains are not used to handle words which starts with "Esp" -string! That is the reason why I used my Kahneman´s system one when I saw google search result page , where was all these strings: "ESP2866", "Esp*" -project and "Failed to write to target RAM (result was 0107)". So I thought very quickly that "This is the right search result to click!"

  Espruino seems to be very interesting project too, I should find time to study Espruino project too!

  Sorry for inconvenience! :-)

  No wifi AP after first successfull (Hash of data verified.) flash installation and boot.

  I did erase again and flashed again with -fm dout -option No led light, no Wifi access point (tried double click and long time button press, no access point after them).

  It seems to me that espurna-1.13.2-itead-sonoff-th.bin is incompatible with my new TH16 device. PCB text is: "Ver 2.1 2017-6-8"

  I changed my programming device to cheap clone FT232BL based USB to UART device and succeeded to erase and write a new image. These settings works for me:
  root@raspberry:/home/pi/espurna# stty</dev/ttyUSB0
  speed 38400 baud; line = 0;
  min = 0; time = 0;
  -brkint -icrnl -imaxbel
  -opost -onlcr
  -isig -icanon -iexten -echo -echoe -echok -echoctl -echoke

  I am satisfied! :-)

  I got the same problem:

  I am using Raspberry Pi GPIO TXD0, RXD0 and GND. Sonoff is powered by its own power supply (240VAC, I am a professional electrician).

  Any quesses what can cause this ?
