My first day with esp8266
I have read some documentation last days. Today I got the board and download the nonos sdk v2 and tried to load the at example following the readme file using esptool:Code: Select all
ze@ze-MacBookPro:~/Downloads/ESP8266_NONOS_SDK/bin$ esptool.py write_flash 0x00000 boot_v1.2.bin 0x01000 at/1024+1024/user1.2048.new.5.bin 0x3fc000 esp_init_data_default.bin 0xfe000 blank.bin 0x3fe000 blank.bin

After that I open the serial port and type AT but nothing come back from the esp8266 :s I tried different velocities also diferent 'at' combinations (at+cr) with no success
I also connect a serial adapter to GPIO2 (uart1 TX) and when use esptool to get flash_id I can see the info on the terminal.
What could be wrong?
