Hi, I tested a program in [new microbit](https://microbit.org/new-microbit/), writing to SD card with SPI functions. The programs writes two lines each time and show 090 after writing, this continues, writing and showing the code again and again. I tried the same code with old microbit, it works fine for it.

That means that there is an error in your code! Can you send me the link for your code?  
It could be a wrong variable or an extension error!  
Please send me the link and I will see what I can do!
