After some playing with my ESP8266-01 with Arduino SDK I wanted to install again the AT firmware on it and I failed.
I tried, from the ESP8266_NONOS_SDK-3.0.5, to instal it as follows:
esptool.py write_flash 0x00000 boot_v1.2.bin 0x01000 at/512+512/user1.1024.new.2.bin 0xfc000 esp_init_data_default_v08.bin 0x7e000 blank.bin 0xfe000 blank.bin
No errors during flashing (see below), but then in normal, not download mode, after power-toggle the ESP8266-01 runs amok
the led is blinking like crazy and console gets flooded with garbage.
Could anyone be so nice and guide me to the correct way? Am quite new to ESP8266-01.
Thanks
