Thanks, it helped!

Another problem is that FLASH_DOWNLOAD_TOOLS can not write/erase area more 2M. Therefore for the firmware 4M-flash have to write twice blank.bin = 2M. Otherwise, the previously recorded user files are not erased.

I tested a firmware 4M-flash on the modified module. The result is similar to other firmware - the files are not recorded in the whole of the available area of flash memory: allows you to record a set of files with a total size of ~ 1720K ~ 1,68M.

Probably not, because EN25F16-100HIP only works in a simple SPI mode. ESP8266 module for exchanging data with a flash memory (as W25Q40...W25Q128) uses Quad I/O.
