board and if LED1 is flashing it is indicating that your Superboot is functioning.
If you don’t see LED1 flashing or any output from your serial port it may indicate
your burning was not successful. The following cases could result in this failure:
1. You might use a notebook and the notebook’s the card reader might not work. We
suggest using an external usb card reader.
2. You might use a bad SD card. We suggest using one whose memory is at least 4G
or SDHC
3. You might use an SD card. Please use a standard SD card which can be directly
connected to your card reader
4. The SD card booting function is integrated in Samsung’s chip and the ROM is
preinstalled. It might not recognize some cards. In this case we suggest you try some
different cards
5. Poor contact might be another reason. In this case you could try a few more times:
by unplugging and plugging the core board and the base board (if your board is a tiny
board) and unplugging and plugging the SD card

need your SD card for system burning you might want to restore your card to what it
