Version Check

[ReeveFernandes]

Hey,

Thank you for your amazing work on HDMI. I tried to compile the same on my system and I am having unexpected error.
This is my screenshot after success complication in Quartus Prime Lite 21.1. There are no fatal errors.

After project was successful compiled, I did the following steps:

1. Generated an .ttf file from quartus.
2. reversed the bits in the .ttf using this code to prepare for uploading.
3. uploaded the file along with an empty sketch on Arduino IDE (I used Emptysketch on prior smaller projects and got desired results, so probably the issue is not with EmptySketch)

I guess the code is uploaded to the board ( and the board resets itself after uploading). Then, I connected my board to an HDMI sink (LG TV) to test the code. I do not get the desired output on the Screen (the gif in HDMI directory). Instead, my TV says there is no HDMI source.

I worked with Dr. Juyang Weng and he suggested to edit this message to explain my issue.

It is my hunch that these error are probably caused due to the difference in versions that are used at the time of compilation and are not compatible.

Would you help me out on this front and provide me with the versions of the following software/hardware you used at the time of making this module:

• Computer OS and version.
• Board OS and version.
• Board FPGA chip version.
• Microcontroller chip version.
• Compilation method and software version. I believe you used Quartus Prime and the Arduino IDE. If you used the BitReversal method from the .ttf file produced by Quartus prime. What program did you use for the same?
• HDMI cable and sink version.

Thank you in advance!

Hello,

Are you able to successfully synthesize and run other programs?

At the time, I was probably using Quartus Prime Lite 20.1. For testing with the MKR Vidor I used the usb blaster library.

(It will take me a bit to get those other answers)

Thanks, Sameer!

From your repo, I tried to compile the MIPI demo and HDMI demo. Although Quartus Prime Lite 21.1 successfully compiled it, the results did not show up as expected!

I will now try to compile the program in the Quartus version and method of uploading you mentioned and see if that renders any promising results! I will update you on the same!

Thanks again!
