Flash Mode: DIO
Flash Speed: 40Mhz
Upload Using: Arduino FTDI Serial

Got answer! AutoDetect firmware…
Communication with MCU established.
Can’t autodetect firmware, because proper answer not received (may be unknown firmware).
Please, reset module or continue.

Fatal exception (0):
epc1=0x40210880, epc2=0x00000000, epc3=0x00000000, excvaddr=0x00000000, depc=0x00000000

PS : I'm using a separate 3.3V power supply from beaglebone.
I'm able to flash the module with NoduMCU (above settings without any error)

Module works fine with AT commands

boot_v1.6.bin                           : 0X00000
esp_init_data_default.bin               : 0XFC000
blank.bin                               : 0XFE000
user1.1024.new.2.bin                    : 0x1000

But not able to program Lua in my module.

Please help!!!
