No, but the "firmware" is just a framework for the rest of the CF to use. With all the hooks in place, there is no need for it to be updated very often. For a proper appreciation of development and release history you need to include package updates and new packages (which run from HDD not Flash, and therefore software not firmware).I see that the last firmware release was in 2017. Has development stopped?
Check out the GIT.Is it possible to get hold of the source code and build instructions?
I doubt it; historically AF has been fairly tight-lipped about it, and considering the effort involved it is not unreasonable he keeps it as his IP. Much of the subsequent development has been with community input, but those initial stages were his toil alone. Also, at the time, it was not clear whether the reverse-engineering involved was strictly legal (I now believe it is, where the reverse-engineering is necessary for the production of compatible products rather than copying the IP).Are there any instructions for building the CF itself?
If you search the forum and Wiki you'll find details about the downloadable GPL software used by Humax and the cross-compilation tools and flash tools that might be used to make the CF.... Is it possible to get hold of the source code and build instructions?
That's not strictly accurate, see this post. This experiment has not been "moulded" into a package yet. (There's a lot of work involved to make it flexible/ useful. So I don't know if it will ever reach release stage.)What has never (yet) been achieved is to command it to display user-supplied text
Not that I know of. Why don't you give it a shot?Has approaching Humax to see if they would make the source available been considered?
I am not so sure about that.The product has been obsolete for some time and any IP issues presumably no longer a problem.
That's probably a version ahead of what's in the HD/HDR build.https://archive.eettaiwan.com/www.eettaiwan.com/ART_8800633476_676964_NP_ad2dbe37.HTM - translated by Google said:Embedded technology
New version of Opera Devices SDK will support Broadcom STB chip
Online time: February 01, 2011
Keywords: set-top box STB BCM7420 BCM7405 BCM7335
Opera Software announced that version 2.9 of its Opera Devices SDK development kit will begin to support Broadcom's BCM7420 set-top box (STB) single-chip platform.
In the future, the Broadcom set-top box application programming interface (API) will integrate the latest Opera browser to provide the Internet environment for cable, satellite TV and digital set-top boxes and other single chipsets. These devices include this generation of products such as BCM7400, BCM7405, BCM7335, and the next generation of 40nm devices, such as BCM7231 and BCM7425.
In addition to the general set-top box application programming interface (API), Opera's software development tool suite uses Broadcom's DirectFB and high-performance graphics to transplant the bottom layer, as well as 2D and 3D image engines to execute web animations and effects. On the latest 40nm devices, the Broadcom decoding and playback hardware built into the software development kit can support high-resolution (HD) videos, as well as high-end features such as SVC and MVC.
