ets Jan 8 2013, rst cause :2, boot mode:(1,6)

Hello people! Currently I'm doing my final year project. I'm using Arduino Mega 2560 as the main microcontroller in this project. While, ESP-01 used as the Wi-Fi module to transfer the data collect from gas sensor MQ9 and sound sensor.

So now I'm having this problem :
ets Jan 8 2013, rst cause :2, boot mode:(1,6)

As i know this problem appear because the ESP-01 is insufficient power.
What should i do to overcome this problem ?

you have io 0 LOW. the esp goes into bootloader mode.
the 1 in (1, 6) should be 3. bit 1 is for io 2, bit 2 is for io 0 and bit 3 is for io 15. io 15 should be LOW for normal boot. io 0 and io 2 should be HIGH
001 is 1
011 is 3 (1+ 2)
111 is 7 (1 + 2 + 4)

i dont really get it... what must i do now to overcome this issue

pull-up io 0 to HIGH
