I can select 'Generic ESP8266 Board', and I have the right serial port selected, but I don't see esptool in the list of programmers.
When I try to upload, I see this :
Sketch uses 207,036 bytes (39%) of program storage space. Maximum is 524,288 bytes.
warning: espcomm cmd: wrong direction/command: 0x01 0x02, expected 0x01 0x08
Uploading 36912 bytes from /var/folders/71/9gbg1bj16jjg0h_7r49pbfv00000gn/T/build7059410809240356286.tmp/WiFiWebServerRPS.cpp_00000.bin to flash at 0x00000000
warning: espcomm cmd: didn't receive command response
warning: espcomm_send_command(FLASH_DOWNLOAD_BEGIN) failed
I'm sure I've just missed a little step somewhere, but I clearly have no idea what I'm doing. Am I meant to install esptool from somewhere else ?
Thanks!
