ESP-01 looks like it's not running any flashed program
Posted: Tue Jan 16, 2018 7:03 amHi!
Totally newbie here, I bought an ESP-01 with some components to start learning about ESP8266:
My setup is the following:
For building the toolchain in Unix I followed this tutorial:
https://primalcortex.wordpress.com/2015/01/09/esp8266-setting-up-native-sdks-on-linux-and-exploring-some-applications/
And I tried to execute the blinky example https://github.com/esp8266/source-code-examples/tree/master/blinky (I had to change the Makefile to set ESPTOOL variable to my correct path.
To compile I go to the blinky directory, which is in the root of my ESP8266_SDK directory and execute
Then to flash i execute
And it looks like everything is okey, so I basically reboot the ESP-01 after connecting CH_PD to GND, but nothing happens.
The blue LED doesn't blink, the only thing which is ON is the red one which is the power LED.
Could someone point out if I'm doing something wrong, or if there is an easier way of programming the esp-01 using the official SDK?
Thanks!

My setup is the following:
- The MB102 is connected through a USB cable to a USB port in my desktop PC and the MB102 is set to output 3.3V
- The ESP-01 is connected to the FTDI through TXD,RXD to RXD, TXD, to GND at GND_PIN and GPIO0_PIN and to MB102+ at VCC_PIN, reset and ch_pd
- After flashing, I reboot the ESP-01 connecting the GPIO0 to MB102+
