I don't mind being patient, but it has been like 3 years since a firmware update.  Can we call the Zero a dead console yet?

They just released Psx.  Wouldn't it be a bit unfair to call it "dead"?
 I feel like this thread should be erased before Devs are like, "ok..f^*% this I'm out" 😂😂
Many volunteer developers feel alienated due to the expectation they are obligated to deliver. In reality, they don't have any obligation whatsoever to any of the people buying the devices (you pay for the hardware, you don't pay for development).

The GCW Zero was slated to be the spiritual successor of the Dingoo A320 with the intention of using OpenDingux to maximize compatibility with previous software releases. The developers aren't working for GCW LLC and have done tremendous amounts of work that are completely invisible to the eyes of users.

The reason why hardware like this is hard to support is due to the notoriously bad Linux support by Ingenic (the GCW Zero uses the Ingenic jz4770 SoC)

Developers don't always work on high profile issues. Sometimes you wouldn't even notice the work that is being done because it's working as intended. It's usually only after things break down that the work developers are doing becomes visible.

Follow https://github.com/gcwnow/ if you want to see what developers are working on. Recent work included moving to devicetree and efforts are being done to get all drivers upstream in the Linux kernel. If you want people to work on HDMI and tv-out you'll have to find a developer with enough spare time to write a KMS driver.

I absolutely understand.  Thanks all for your hard work!

Actually no, because 'gcwnow' is like a virtual user that we use to store the repos, so it shows no activity.

Instead, you can follow the https://github.com/gcwnow/linux repository, that's where all the fun stuff happens.

That is correct. So perhaps people can follow the individual developers working on the firmware.

Cleaning the shit out of the drivers, so that we can push them upstream. Which is mostly done after months of hard work, but some nasty bugs are left that need attention. Then once we're happy with it we'll make a FW update, and after that one work on DRM/KMS driver for TV-out and HDMI can start.

Just out of curiosity, what will this mean for end users, other than ensuring the drivers continue to function in the future? More overall stability perhaps?

For the end users, not much. It allows us to keep updating to recent Linux kernels with shiny new features. And cleaning up the drivers makes debugging much easier, and would allow advanced features like suspend/resume to work (not working yet). Some drivers already work much better than before (e.g. the SD card driver).

From the FW developer point of view, having the drivers upstream means that we don't have to keep up with the upstream changes anymore at every single release of Linux, other developers do it for us.

About the KMS driver, not only it's required for HDMI and TV-out, but it will also allow us to update to the latest "etnaviv" (GPU driver). Since we only have a framebuffer driver right now (instead of KMS) we're stuck with a really old version  :'(

Once this round of updates (hopefully the last ones needed to bring in all the promised functionality) are finished, will there be one more round of production on the console?

Zero is dead.
Most people only care about GPD Android and Windows hand-helds.

I for one love my GCW Zero as is very portable and the 4:3 aspect screen is perfect for retro gaming!  Also, the battery life is amazing.

hopefully there is still some scene who likes GCW-Zero and wants/can get a new firmware to enable TV output and USB OTG.


but... is shameful that even a Chinese portable console of 12 euros have TV output
while the GCW-Zero which costs 150 euros, not.  ???

You are comparing apples to oranges here.  The GCW Zero is far more complex than the link you provided.  The "PVP" is only capable of playing NES games -- as it is a NES-on-a-chip console, and there's no HDMI out, it's composite -- which is far easier as well.

the case is that the GCW-Zero has ¡¡no composite output/TV analog!!

My dream is to connect it to a CRT TV.

I for one say just keep on doing what you are doing.  When the Firmware update and KMS drivers are good to go, that is great, but don't rush things. 

See that too often with Linux development.  Push code out that isn't stable or tested enough. 

I like my GCW as it is now, and any improvements/update from the devs will be viewed as much appreciated.
