Corrupt HDMI output #17
Comments
Hi. Tested today with two other different HDMI monitors, same bug MEGA65.with.VGA.Monitor.mp4However, connected to a VGA monitor it works perfectly |
@JohanP9964 Thank you - I highly appreciate your diligence and support. Great to hear that VGA works, that means that the core itself works and we "only" have a HDMI challenge. Adding @amb5l : Adam, is there any chance that you can run the ZX Spectrum core through your HDMI analyzer? Here is the core: https://files.mega65.org?id=bdaeb7e0-9fc8-4185-99de-104d01229f27 |
To analyse the HDMI output I would need a data capture file - this is generated by connecting the HDMI source to a Digilent Zybo Z7 board. If you provide me with step by step (beginner) instructions I could try it with my MEGA65? EDIT: just saw @MJoergen comment, I will wait for a data file from him. |
@sy2002 Actually, looking at the original video in this issue, I was thinking: Could this be a reset problem? In other words, you might want to change line 268 in
I'm quite positive that this will fix the issue reported here. The above line is a very recent change in the M2M framework, so you could also consider upgrading the ZXUno core to the latest M2M version. But the above single-line change can be performed regardless. |
For reference, this is the corresponding commit in the C64 repo: |
@MJoergen Cool! Thank you. I will try this and share a test build with @JohanP9964 . |
@JohanP9964 : Can you please test this experimental ZX Uno core: Does it fix the HDMI issue for you: zxutst.zip |
Hi everyone. It works now, great job :) New.Core.v1.1.mp4 |
Awesome - thank you @JohanP9964 for reporting this and for testing. You helped to improve the quality of the core. I will release an official update on the FileServer. |
Fixes HDMI edge case where nothing but vertical colored lines were shown on screen. (Fixes GitHub issue #17)
On @JohanP9964 's HDMI monitor, the output of the core looks like this:
New_Core_Video_1.mp4
We ruled our these things:
Also interessting: The C64 core V5 works!
What we do not know yet: If VGA works. @JohanP9964: Please test with VGA and report back here.
@MJoergen Any clue what this could be?
