- MW 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?
Most PC's have 1Gb ethernet links, and I note your connection message indicated 100 Mbps. Wondering if you have a bad cabl... - MR 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 in, the link light on the dev board's ethernet will give a really quick flash, also windows will recognize the connecti...
- AD 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 Ethernet PHY Reset. If this was set low, the PHY would be held in reset. That being said, the boot log shows that this GPIO s...
- MR 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's what I got...

- SS 08:06 AM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot
- Hi Dan,
Thanks for posting the instructions and looking at the higher resolution operation. This is very useful as it's possible we'll want to support a resolution that needs greater than 4MB for a framebuffer. We'll be using these ...

- DV 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 to add support for CONFIG_CMA and CONFIG_DMA_CMA, which allowed the altera vip frame buffer driver to allocate enough co...
- DV 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'll try setting it higher and see if I can get 1080p working today.
Thanks,
Dan

- MW 08:21 PM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot
- Can you up the video ram buffer available for allocation using the kernel parameter of the format below?
- DV 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 caused the kernel to crash when it tried to allocate the RAM for the frame buffer to use. 720x576 appeared to boot fine but m...
- DV 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 build is finished and (fingers crossed) I'm able to get video.

- SS 08:10 AM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot
- Hi Daniel,
I saw the project got pushed, thanks.
When do you think you can put together those instructions for updating the resolution?
Thanks a lot,
Steve

- DV 09:59 AM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot
- Hi Steve,
I'll cleanup and push the project today. I'll also go through and write down what needs to be updated in order to change resolution, I think it will be qsys, device tree, and maybe the initialization code for the HDMI chip b...

- SS 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 get a message saying out of range signal. I don't understand how I saw the yocto splash screen on this monitor at some... - DV 02:18 PM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot
- Sorry about that, it's attached now
- SS 01:41 PM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot
- Can you post that image for me to try?
- DV 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 set my monitor's image size to auto instead of wide then it only showed up as a black screen. When I set it to wide I wa... - SS 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 are a bit more forgiving with the back porch value than the monitors, and this latest build works on both.
- DV 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.
- SS 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 same as those used in the AD9889B programming guide for 720p-60. See attached screenshots. It may be that the display's I...
- SS 11:51 AM FPGA Development: RE: HDMI Output splash screen is intermittently displayed on boot
- No luck, same result, just a black screen.
- DV 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/control lines to match what the microtronix's example project used. It did work in my dev kit.
Let me know how it goes
