Firmware

All versions are available on the firmware site.

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, 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.
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

hq2x-<branch> / std-<branch>

These are legacy branches, if doing a WiFi update from a v2.3.x or v3.0.x firmware.
