Dear collegues,

I want to store some data on micro-SD card. I tried the example sketches, but my problem is that after inserting the micro-SD card into slot the board stop working - its serial port disapears from the IDE and nothing can be done. I thing that my card is not bootable so it is not related to the firmware desperately trying to find some boot sector on the SD card... Or I am mistaken and i did overlook something?

Thank you for your answer, best regards,

Hi, sjlegr,

First, see the 86Duino Hardware Introduction to know the "Boot Sequence" in section 2 :
So, if we want to save the data on SD card, need to build an empty SD card to be used by the SD Library.

There are two methods to save the data on SD card :
1. Build an empty SD card and still boot from SPI Flash, refer to the tutorial :;lang=TW
(now, it is only traditional chinese, we are translating to English)
2. Build a 86Duino environment on SD card and boot from SD card, refer to the tutorial (English version) :
