[U-Boot] [PATCH 1/4] mx6cuboxi: Add HDMI output support
From: Fabio Estevam fabio.estevam@freescale.com
Add HDMI output using PLL5 as the source for the IPU DI clocks, and accurate VESA timings.
These settings are based on the patch from Soeren Moch smoch@web.de submitted for the tbs2910 mx6 based board.
It allows the display to work properly at 1024x768@60.
This should make the hdmi output signal compatible with most if not all modern displays.

Since we have FEC do we really need to add ASIX as well? Also, what devices did you test this with for USB? I grabbed a Sandisk USB drive and on the i2eX I have, the bottom USB port doesn't see it and on the top I get: scanning bus 1 for devices... failed to set default configuration len 0, status 80000000

I tested with USB pen drive and USB keyboard and it could recognize them.
Only the bottom top works for me and the same is seen on Solidrun's U-boot.

How many USB pen drives do you have handy? I confirmed that my keyboards don't work on my Allwinner board (A20 OLinuXino Lime2) but the pen drive does (scanned, loaded and crc32'd a file). I'll try and do the same test on my Sabrelite shortly.

Is CONFIG_SYS_USB_EVENT_POLL defined in the config? I found that without that usb input was not reliable. Even with it enabled some wireless keyboards behaved poorly.

For the keyboard it may indeed help but what about the USB pendrive?

Just checked and yes it's set. I think I also had these not working with the Solid Run tree either so I'll just call 'em both weird.

In this case I think there is no reason to not merge this as is and fix/improve it later.

Does it improve if you remove CONFIG_SYS_USB_EVENT_POLL and use
#define CONFIG_SYS_USB_EVENT_POLL_VIA_CONTROL_EP , instead?
While at it, please also try to add:
#define CONFIG_EHCI_HCD_INIT_AFTER_RESET

Same drive is good in my Sabrelite btw.

There are users of Cuboxi and Hummingboard that use these boards without connecting them to a USB/serial adapter.
Allow such usage by allowing the HDMI port to act as stdout and USB keyboard as stdin.
The serial console still also works as stdin/stdout.

But my keyboards (which iirc also caused problems on Allwinner) don't work but I don't think that's a Hummingboard/mx6 problem.

Add HDMI output using PLL5 as the source for the IPU DI clocks, and accurate VESA timings.
These settings are based on the patch from Soeren Moch smoch@web.de submitted for the tbs2910 mx6 based board.
It allows the display to work properly at 1024x768@60.
This should make the hdmi output signal compatible with most if not all modern displays.

I wasn't able to test this as the HDMI TV I'm using doesn't support this resolution (it is admittedly ~9 years old, the closest resolution it does support is 1280x720@60). How complicated would it be to support multiple resolutions?

There's edid support in the sunxi display driver..

(Sorry about the double post.. gmail..)
There's edid support in the sunxi_display driver:

Could pull it out as a share it.

Could you try to use these VGA timings to see if your TV can handle it?
.name = "HDMI", .refresh = 60, .xres = 640, .yres = 480, .pixclock = 39721, .left_margin = 48, .right_margin = 16, .upper_margin = 33, .lower_margin = 10, .hsync_len = 96, .vsync_len = 2, .sync = 0, .vmode = FB_VMODE_NONINTERLACED
If it works, then you could try 1280x720 manually as well. The IPU clocks will need to be probably changed to reach this resolution.
Currently we are not flexible with the IPU DI timings in U-boot, but we could try to improve it in the future.

Fabio Estevam

No luck. The TV does support 640x480 when plugged into my laptop,
I did manage to verify with a display that supported 1024x768 and that worked fine.

Thanks for testing.
Could you send us your Tested-by tag?
