TINY4412SD Start-up disk production

One. Use the Sd-flasher tool to burn superboot to sd card.

1.sd-flasher.exe will partition the SD card, the first partition is 130M for storing Superboot4412, the remaining space is formatted as FRIENDLYARM partition for storing system file images.
Some SD cards less than 256M are not available and we recommend using at least 4G SD cards.

2. Open the CD \tools\ directory, unzip sd-flasher-1327.7z get Sd-flasher.exe burn write software, start it, please note that you need to open the software as an administrator.

3. When you start the Sd-flasher.exe software, the "Select your machine ..." dialog box pops up, where you select the "mini4412/tiny4412" entry:

4. After clicking Next, the Sd-flasher main screen will pop up, click Scan, List your SD card, select it, then click "Relayout" to split the SD card, note that this operation will empty the data inside the SD card and then repartition it.

5. After the split is complete, click "Scan" and you will see that the Available has become available, indicating that the split is complete:

6. Click the button to find the superboot4412.bin you want to burn (default is located in the CD images/directory, such as the disc directory has been moved, do not put in the Chinese directory),

7. Point "Fuse", Superboot4412.bin will be safely burned to the SD card in the unformatted area, later you use Sd-flasher to make SD card, no need to perform relayout operation, FAT32 partition data will be preserved.

8.Bootloader is written to the SD card is not visible, how to detect it? The method is to plug the SD card into the development Board of the connected serial port, and set the S2 switch on the development Board to "Sdboot" mode, after the boot, the serial port has information output, for example:

Indicates that the Bootloader has been written to the SD card, if the serial port does not output, the description does not burn successfully.
There are several reasons why this may not work, and there are workarounds:
11. Using the notebook card reader, it is recommended to use the external USB card reader, note that some external USB reader is not a good
22. Using the fake SD card, please use genuine, preferably 4G or above SDHC
33. Using the microsd+ card cover, please use the normal SD card, because the way of the card sleeve is very easy to lead to poor contact
44. The possibility of not using the SD card to boot due to bad contact is relatively large, it is recommended to try several times, which includes (1)
