Hi everyone, I am currently using the "TinyCircuits TinyShield Flash Memory: Sketch Example" for arduino, but when compiling and loading it to the board it does not allow me to write to the flash memory.

This is the result I get on the serial monitor:

---------------------------------------------------------------
Initializing Flash Memory...

Using writeByte...
Write failed!
Using readByte...
The byte on page 2468 at position 78 is: 0
---------------------------------------------------------------

I have tried using the SPIFlash.h and SPIMemory.h libraries, but I keep getting the same error.

Does anyone have an idea what could be happening?

I would greatly appreciate your help!!

Greetings.
