Flash (using [esptool](https://github.com/themadinventor/esptool)):
```
$ esptool.py --port /dev/ttyUSB0 --baud 230400 \
write_flash --flash_mode=dio --flash_size=32m \

```
The output can be made to fit in 512KB (4Mb), but stock linker scripts do not reserve enough space for code.
Custom linker script is provided for that, so you can use it for smaller devices like so (example that will work with ESP-01):
```
$ make clean; make BOOT=none APP=0 SPI_SPEED=40 SPI_MODE=qio SPI_SIZE_MAP=0 LD_FILE=ld/eagle.app.v6.512.compact.ld
