The problem for example here I can see 3.3V output of the raspberry is used, but this pin can just out a little current.
Edit: Also I try to use Arduino IDE to program the esp8266 from the raspberry, or it is possible to use arduino for only compiling the firmware and then upload the .hex file with esptool for example ? Or will the Arduino IDE recognize the serial port maybe ?
It is possible to flash the ESP8266 12-F with the raspberry UART pins ? Has anyone ever done this?
I’ve used the USB ports for this with
esptool.py --port /dev/ttyUSB0 erase_flash esptool.py --port /dev/ttyUSB0 write_flash -fm dio 0x00000 nodemcu.bin
I use “nodeMCU” style boards that have a micro USB jack (so using a normal micro USB cable). I also thought hardware flow control, which the Pi UART conventionally lacks, was necessary, but looking around this is not be the case, you just have to hold CH_PD and/or some other line high. So it should be possible.
I’ve found the serial interface on the ESP a bit fussy — as in good ol’
minicom is not reliable with it, the best thing seems to be
miniterm.py, which is part of the
