Maybe this way:??:    


Option System SPI Clock (=SCK), MOSI (=SDO), MISO (=SDI)

If this is correct, i think it would be a good Idea to put it in the Manual.  
Just my Opinion.

WIKI says:

   MOSI (Master Out -> Slave In) also SDO (Serial Data Out) or DO
   MISO (Master In <- Slave Out) also SDI (Serial Data In) or DI
   SCK (Serial Clock)

So Maker PI PICO is not compatible with MMBASIC and SD Card?

That is exactly what the manual says.

  Quote  There are a number of ports and pins that can be used (see the section PicoMite Hardware) but this example uses SPI on pins GP18, GP19 and GP16 for Clock, MOSI and MISO.
OPTION SYSTEM SPI GP18, GP19, GP16 (MM Basic Manual p36)

Hallo Zweifinger,

but with this Board the pins are routed to fix Port, see Picture above.
So it is not compatible ?!

Try
  Quote  option system spi GP10,GP11,GP12
as Peter suggests.

10, 11, 12

Not:
10, 12, 11!

Just type

option system spi GP10,GP11,GP12
option sdcard GP15

The labelling on the card is from the SDcards perspective hence SDI connects to MOSI

This is the card I developed the Picomite on. I do know what I'm talking about

The Error is thrown before i can use this command.

It is also the wrong series.
First :

OPTION SYSTEM SPI GPxx, GPyy, GPzz

And then:
MMBasic must be told that there is an SD card attached and what pin is used for the Chip Select signal:
OPTION SDCARD GPnn

Now initialization works like a charme.

Correct! What's going on today? Series of misunderstandings.
