hello @Marzogh.

Im having some issues with the SPImemory library, specifically it doesn't work for the writing operations.

Hardware:

Arduino UNO

W25Q80BV

Wiring:

1cs ----> pin10

2DO ----> MISO

3WP ----> 3.3v

4GND ----> GND

5DI ----> MOSI

6CLK ----> SCK

7HOLD ----> 3.3v

8VCC ----> 3.3v

I interfaced the Arduino and Flash using the level shifter.

and FlashDiagnostics line 40 has been changed to:

SPIFlash flash(10);

The library version 3.2.1 and 3.2.0 both do not work.

Any help is appreciated.

The output is below
