STM32F103 Mass Storage Device Bootloader
Device: STM32F103C8T6 (Flash size: 128KB )
My example:
| Name | Address |
|---|---|
| Appcode starts from: | 0x0800_8000 - 0x0801_9999 (96KB) |
| (Unused) starts from: | 0x0800_3100 - 0x0800_7FFF (20KB) |
| Bootloader starts from: | 0x0800_0000 - 0x0800_30FF (12KB) |
Simulate a USB removable disk (FAT32). The content of firmware.bin is mapped to Appcode area. Hence, the size of firmware.bin is also 96KB.
Update Appcode Procedure:
- Convert the iHex file to bin file
- Drag and drop the bin file to update the appcode
Only tested on Windows 8.
MacOSX doesn't work properly
During power up, the bootloader will check the content of 0x0800_8000 exists or not. Hold PA0 (Connect to GND) during power up can force to enter bootloader mode.
