Espruino WiFi with Adafruit Micro-SD Breakout board

Hello,

I'm experiencing the exact issue as this post:
http://forum.espruino.com/conversations/­315054/

console.log(require("fs").readdirSync())­;  
Unable to mount media : NOT_READY

It worked one time only between a lot of trials without changing any thing.
I'm using a new 16GB micro-sd card formatted to FAT32 and works fine on windows 10.

All the connections and power are OK.

CS => B1
DI => A7
DO => A6
CLK => A5
GND => -
3v => 3.3v

Timeout of 3 seconds between:

SPI1.setup({sck: A5, miso: A6, mosi: A7});
    E.connectSDCard(SPI1, B1);

and

console.log(require("fs").readdirSync())­;  

I also tried a pullup resistor on pin B1 I don't know if I did it right:

pinMode(B1, 'input_pullup');

I'm using Espruino WiFi with firmware 2v08.

Do I need to connect CD pin somewhere too?

All I need is stable initialization when powering up espruino wifi.

I planning to use the button for E.unmountSD(); before powering off.

Thank you.
