### Initial Setup
2016-06-23 20:45:07 +02:00
Install the firmware on the ESP:
The ESP must be set into the bootloader mode, like [this ](https://www.ccc-mannheim.de/wiki/ESP8266#Boot_Modi )
The firmware can be downloaded with the following script:
< pre >
cd os/
./flash.sh ttyUSB0
< / pre >
2019-07-26 21:33:48 +02:00
Connect to the ESP via a terminal emulator like screen using a baud rate of 115200. Then format the filesystem and reboot the ESP with the following commands:
2016-06-23 20:45:07 +02:00
< pre >
file.format()
2019-07-26 21:33:48 +02:00
node.restart()
2016-06-23 20:45:07 +02:00
< / pre >
Then disconnect the serial terminal and copy the required files to the microcontroller:
2016-04-12 18:07:25 +02:00
< pre >
2016-06-23 20:45:07 +02:00
./tools/initialFlash.sh /dev/ttyUSB0
2016-04-12 18:07:25 +02:00
< / pre >
2019-04-18 16:32:35 +02:00
### Upgrade
Determine the IP address of your clock and execute the following script:
< pre >
./tools/remoteFlash.sh IP-Address
< / pre >
