Translated from notes included with firmware package released March 12, 2011 for SuperPAD II
Typical firmware upgrade method：
1 prepare a microSD card formatted to FAT32
2 download the new firmware files
3 place the firmware update files (firmware-discovery and firmware2) into the root directory of the microSD card
4 put the microSD card into the powered down device, and proceed to turn the device on to begin the automatic firmware upgrade process.
5 when the firmware upgrade is complete, remove the microSD card
6 use the reset button to restart the device
Additional notes
To upgrade, place the files to a microSD card formatted to FAT32.
The card must contain the file firmware2, along with the files bootloader-discovery or firmware-discovery.
Corresponding to:
firmware2 ＋ bootloader-discovery: update firmware data contained in NOR flash (bootloader)
firmware2 ＋ firmware-discovery: update firmware data contained in SD card (internal ROM)
firmware2 ＋ firmware-discovery ＋ bootloader-discovery: update firmware data contained in NOR flash (bootloader) and SD card (internal ROM)
Caution: Unless the device fails to turn on, avoid updating the NOR firmware data
