Startup Mode (Write): This is the standard mode for creating a bootable SD card. It writes the firmware image to the card, setting it up so that the target device can boot directly from the SD card slot. This is often used for testing new operating systems without flashing the internal NAND memory.
Upgrade Mode (Firmware Update): This mode is particularly valuable for recovery purposes. It creates a card that forces the device into a firmware upgrade state. If a device has corrupted internal memory or requires a system restore, an SD card written in "Upgrade" mode can automatically flash the internal storage upon boot, effectively restoring the device to a factory state.
Restore Format: Embedded systems development is often iterative. The "Restore Format" option allows users to wipe the specialized partitions and boot sectors created by Phoenix Card, reformatting the SD card back to a standard FAT32 configuration for general use. This solves a common frustration where Windows Explorer cannot read or format cards previously configured with Linux partition schemes.
