08:25 PM Software Development: RE: Ethernet not coming up

Just out of curiosity, have you tried a different cable? Do you have a switch or anything available to try?
Mos... Michael Williamson

06:00 PM Software Development: RE: Ethernet not coming up

Well it's doing it again. No ethernet. Tried running the gpio test, didn't do anything. When I plug an ethernet cable... Michael Ruen

04:27 PM Software Development: RE: Ethernet not coming up

I'm not sure why it would fail like that, then recover without any real changes. The HPS_GPIO28 controls the Etherne... Adam Dziedzic

12:56 PM Software Development: RE: Ethernet not coming up

I may have fixed it. On the prebuilt image there is the program gpiotest. I ran it just for the heck of it, and here'... Michael Ruen

12:22 PM Software Development: Ethernet not coming up

I turned the board on today with my custom SD image (FPGA, kernel, file structure...) that I have been using the past... Michael Ruen

06:21 PM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot

Alright, so I was able to get 1080p working. I had to make some changes to the defconfig for the hdmi example. I had ... Daniel Vincelette

10:58 AM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot

That's a good idea Mike, it looks like the kernel defaults vram to 4MB but for this framebuffer 8MB+ is required. I'l... Daniel Vincelette

Can you up the video ram buffer available for allocation using the kernel parameter of the format below?... Michael Williamson

06:29 PM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot

Alright my testing today wasn't as successful as I'd liked. I tried both 1920x1080 and 720x576. Doing 1920x1080 cause... Daniel Vincelette

09:38 AM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot

Hi Steve,
I'm testing this now. Hopefully it's just the mods to the device tree/qsys project. I'll update once my ... Daniel Vincelette

Hi Daniel,
I saw the project got pushed, thanks.
When do you think you can put together those instructions for ... Stephen Snyder

Hi Steve,
I'll cleanup and push the project today. I'll also go through and write down what needs to be updated in... Daniel Vincelette

03:52 PM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot

Hi Dan,
So I'm still not getting any output on my monitors. However, I tried adjusting the monitor settings and I... Stephen Snyder

02:18 PM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot

Sorry about that, it's attached now Daniel Vincelette

01:41 PM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot

Can you post that image for me to try? Stephen Snyder

01:34 PM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot

Awesome, I'll glad it did work on the TV!
I was able to recreate what I think you're seeing on your monitor. If I ... Daniel Vincelette

12:32 PM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot

Awesome, thanks.
I tried a large screen Samsung HDTV and your latest build works.
I'm hoping that the HDTV's ar... Stephen Snyder

12:10 PM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot

Good catch, I'm doing a build now with the those back porch values. I'll let you know when it's finished. Daniel Vincelette

12:00 PM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot

One thing of note, based on the original qsys file from the wiki page, it seems the back porch values are not the sam... Stephen Snyder

11:51 AM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot

No luck, same result, just a black screen. Stephen Snyder

11:14 AM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot

Hi Steve,
Attached is a new image. The only thing I changed was that I updated the output delays for the data/cont... Daniel Vincelette
