Read the posts carefully. ChrisSparks uses a LoLin V3 board which has 4MB flash memory. Hence, his flashing parameters are different and the address for esp init data is different as well.

We're currently having a discussion about 512KB vs. 1MB flash on the ESP-01 at https://github.com/nodemcu/nodemcu-firm ... -259267464. I'm a bit puzzled.
