Nice build.

Nice write-up! I will have to bookmark this one and come back to as a reference. Thanks for sharing!

Changed the SPI pins:

// SPI
#define SPI_FLASH_MOSI_PIN  11
#define SPI_FLASH_MISO_PIN  12
#define SPI_FLASH_SCK_PIN   10
#define SPI_FLASH_CS_PIN    9

Set the output to USB, because I'm using PicoProbe:

pico_enable_stdio_usb(flashtester 0)
pico_enable_stdio_uart(flashtester 1)

It built without problems:

I ran it in debug mode, Flash init part and reading the register works. Still need to read further info.

I'm using ST Micro M25P16-VMN6P NOR Flash 16MBit, and have not verified if it's compatible, or if I need to do something with the hold and protect pins. Just ran the example.
