# Firmware
All versions are available on the [firmware site][firmware].
The firmware consists of 3 parts:
#### FPGA firmware: https://dc.i74.de/fw/
FPGA firmware comes in 3 different file types:
- `.dc` Binary configuration for WiFi/Web console update.
- `DCxPlus-v2.dc`
Newer style firmware package containing both `std` and `hq2x` firmware.
This is used in firmware > v4.0.
- `DCxPlus-default.dc`
Legacy firmware package for firmware < v4.0.
- `.jic` Active serial configuration file for use with programmer (e.g. USBBlaster).
**Obsolete** as the production DCHDMI does not have the JTAG connector on board.
- `DCxPlus-hq2x.jic` Standard firmware
- `DCxPlus-std.jic` Relaxed firmware
- `.rbf` Raw binary configuration file.
- `DCxPlus-hq2x.rbf` Standard firmware
- `DCxPlus-std.rbf` Relaxed firmware
These files are used to create the `.dc` file(s)
#### ESP firmware: https://dc.i74.de/esp/
- `4MB-firmware.bin` ESP firmware.
- `4MB-littlefs.bin` ESP Filesystem image. ***Used for initial programming.***
#### ESP web console: https://dc.i74.de/esp/
- `esp.index.html.gz` Web console `index.html`
#### Files used by WiFi update
- `https://dc.i74.de/fw/<branch>/DCxPlus-v2.dc` (> v4.0)
or `https://dc.i74.de/fw/<branch>/DCxPlus-default.dc` (< v4.0)
#### Important
If you want to manually update your firmware as described [here](Web_console.md#i-dont-want-to-connect-my-dchdmi-to-my-wifi-network-how-do-i-update-manually), make sure alle 3 files are from the same branch.
#### Available firmware versions (branches) (aka `Firmware Version` in Web console setup)
##### master
Stable branch. This is the recommended setting for most users.
- FPGA: https://dc.i74.de/fw/master
- ESP/Web console: https://dc.i74.de/esp/master
##### develop
Development branch. Release candidates are released here.
- FPGA: https://dc.i74.de/fw/develop
- ESP/Web console: https://dc.i74.de/esp/develop
##### experimental
Experimental branch. Alpha/Beta versions are released here. **Use with caution!**
- FPGA: https://dc.i74.de/fw/experimental
- ESP/Web console: https://dc.i74.de/esp/experimental
##### bleeding
Bleeding edge branch. Daily builds and features in development is done here.<br>
**Use with extreme caution, as these may require restoring from a bricked console via serial port!**
- FPGA: https://dc.i74.de/fw/bleeding
- ESP/Web console: https://dc.i74.de/esp/bleeding
##### vX.Y
Previously released firmware versions.
- FPGA: https://dc.i74.de/fw/vX.Y
- ESP/Web console: https://dc.i74.de/esp/vX.Y
For a list of all versions:
- FPGA: https://dc.i74.de/fw/
- ESP/Web console: https://dc.i74.de/esp/
##### hq2x-\<branch> / std-\<branch>
These are legacy branches, if doing a WiFi update from a v2.3.x or v3.0.x firmware.
