The image produced is `firmware-combined.bin`, to be flashed at 0x00000.
Troubleshooting
---------------
While the port is still in alpha, it's known to be generally stable. If you
experience strange bootloops, crashes, lockups, here's a list to check against:
- You didn't erase flash before programming MicroPython firmware.
- Firmware can be occasionally flashed incorrectly. Just retry. Recent
esptool.py versions have --verify option.
- Power supply you use doesn't provide enough power for ESP8266 or isn't
stable enough.
- A module/flash may be defective (not unheard of for cheap modules).
Please consult dedicated ESP8266 forums/resources for hardware-related
problems.
