Bug Report

Describe the bug

I am trying to run the SPIMemory library with the Arduino MKR WAN. I have updated the pin connections following this documentation (https://github.com/arduino/ArduinoCore-samd/blob/5dced38e81e6001a4b6e237e3462bc8db962127a/variants/mkrwan1300/variant.h#L220), i.e. with SPIFlash flash(FLASH_CS, &SPI1 (and various variants thereof, i.e. with SPIFlash flash(32, &SPI1), etc.).

When I run the FlashDiagnostics.ino code, I still get the error message:
SPIMemory Library version: < 2.5.0
No comms. Check wiring. Is chip supported? If unable to fix, raise an issue on Github

I actually have v. 3.4.0 of SPIMemory installed, and did un-comment RUNDIAGNOSTICS in the header file before I ran the FlashDiagnostics script.

At this point, I don't know whether this is a hardware issue, or a software bug (though I have reproduced this problem with 5 separate units, all of which show the same behavior). Since the error message says to post an issue on GitHub, that's what I'm doing.

• Make sure you have run FlashDiagnostics.ino with #define RUNDIAGNOSTICS uncommented in SPIFlash.h. Paste the relevant sections of the output from your Serial console when you run FlashDiagnostics.ino.here:

Initialising..........

SPIMemory Library version: < 2.5.0

No comms. Check wiring. Is chip supported? If unable to fix, raise an issue on Github

• If you have a problem with a particular function, call the flash.error() function (after you have made sure you have started up your Serial port with a Serial.begin(BAUD) ). Provide details of the function, the data given to/ expected from the function and the error code here: (Please repeat this for every function you have an error with)
  - Function: (e.g. writeByte())
  - Data: (e.g. 3.14 or Struct)
  - Error code: (e.g. 0x0A)

To Reproduce

Provide a minimal code snippet example that reproduces the bug (If you're using one of the examples that came with the library, just tell us which one instead of pasting the entire example's code). Please make sure you wrap any code in the proper code blocks like below

FlashDiagnostics script, with L44 commented out, and L47 set to SPIFlash flash(FLASH_CS, &SPI1).

Expected behavior

Ought to be able to connect to the chip, and run the diagnostics script.

Software environment (please complete the following information):

• Library version: v3.4.0
• Arduino IDE version: 1.8.19
• OS: Windows 10
• Micro controller platform: MKR WAN 1310
• Flash/Fram memory module: W25216
