There is indeed a different firmware that needs to be flashed. You can check out my tutorial series on Hackaday which goes into that. Refer to step 5 in this tutorial: https://hackaday.io/project/160006/instructions You need to erase the flash, and then flash the ESP8266_NONOS_SDK-2.1.0-18-g61248df/bin/esp_init_data_default.bin file.
That's not a project error rather than esp itself When I'm connection ESP-01S to 3.3V I get
load 0x40100000, len 1856, room 16

And if I connect it to 5V (4.8) I see

But nevertheless it's not working
Hello,
I'm new to the esp8266, although not entirely unfamiliar with computers in general, but please don't hesitate to dismiss this issue if there is something fundamental I haven't understood.
I'm using an esp-01 module, the blink sketch from the Arduino 2 IDE works as expected after flashing and resetting, so my hw-setup appears to be working.
I've built esp-open-sdk under MacOS 10.12.6.
After make && make flash in the examples/blinky directory the following happens on the serial console after I disconnect GPIO0 from gnd and reset.
I have kept the
static const int pin = 2;
definition in blinky.c and connected GPIO2 to a led/resistor. When I'm usingpinMode(2, OUTPUT);
in setup() and usingdigitalWrite(2, LOW/HIGH);
in the arduino code the led blinks as expected.I've also manually ran an esptool.py erase_flash before make flash which didn't make any difference.
Is there any special boot-firmware or similar that I need to flash before I can use the esp-open-sdk toolchain?
