I know my wiring is correct because i allready had it working with code from the Arduino IDE.
I can't show you the wiring because it is on a pcb. There are no wires. (Look ma! No wires :) )

See the attached schematic.

I tried the software SPI again and removed the "NodeMCU." before the pin. Like this:
var s = new SPI(); s.setup({mosi:D7, miso:D6, sck:D5}); E.connectSDCard(s, D2); console.log(require("fs").readdirSync());And then i get this output. Maybe this says something to anyone?

Can it be that i should use the SPI2, because of the flash memory beeing attached to SPI1?
Is SPI2 dissabled in the firmware from the earlier post, or is it a matter of the ESP8266 not beeing able to find the SPI2? -
I tried both. But in the first place i always try to copy-paste-enter it line by line in the left terminal frame.

Ah, that worked great!
Seems i got my pin assignments correct.

I found, that when i change my CS pin to NodeMCU.D5 instead of the (accually) used D4, i get a 'Connection lost' error. When i use D4 i get 'SD card not found!'
I use MOSI GPIO13, MISO GPIO12 and SCK GPIO14. Anyone knows the NodeMCU.Dx replacement for GPIO12? I guess it is D6 but not sure...

I allready tried that first. And i tried again to be shure just now.
in the first section i did only your code from the last post, and the second i added one line to call for the FS library. Both didn't work... :(| __|___ ___ ___ _ _|_|___ ___ | __|_ -| . | _| | | | | . | |_____|___| _|_| |___|_|_|_|___| |_| http://espruino.com 1v86.113 Copyright 2016 G.Williams Espruino is Open Source.

using this:
function onInit() { var s = new SPI(); E.connectSDCard(s, NodeMCU.D4); s.setup({mosi:NodeMCU.D13, miso:NodeMCU.D12, sck:NodeMCU.D14}); // see what's on the device console.log(require("fs").readdirSync()); } onInit();i still get the same output:

Indeed! it was formatted as FAT16 before and later formatted as FAT32.
