| Problem | Likely Cause | Solution | |---------|--------------|----------| | File transfer stalls at 0% | Wrong baud rate / poor wiring | Double-check TX→RX cross-connection. Lower baud rate to 9600. | | Checksum mismatch after download | Noise on serial line | Use shorter cables, add 10k pull-ups on TX/RX, enable hardware flow control if supported. | | Target doesn’t run new code | Wrong file format (e.g., .HEX vs .BIN) | Ensure bootloader expects raw binary or Intel Hex. Convert with objcopy if needed. | | Android “USB device not recognized” | Incompatible serial chip driver | Use a CP2102-based adapter (CH340 often requires root on older Androids). |
