I had assembled a board with esp8266ex bare chip with 4MB eeprom for esp and also can be shared with host MCU. I had gone through some googling and found that using eeprom function I am able to write data in eeprom using esp8266ex. But I had seen the limitation of 4KB. Then I had researched more than I found that there is a way to increase that.

So my question is, Is there are any issue if I changed that 4KB to 2 MB or more in esp8266 library?

I am using arduino IDE for Esp programming.

    I tried the spiffs, every time it shows unable to find file, but the file path is right and even the file name. – Vaibhav Jul 11 '19 at 18:15

    Actually I tried the basic example in which it will go to the directory, open the file and try to print the file data on serial monitor. But I always for the result as Unable to open the file. – Vaibhav Jul 11 '19 at 18:23
