FSL gnome release package and VGA display output ?

philippecavenel — Wed, 02 Nov 2011 20:04:29 GMT

Hello,

I can't get a VGA output display with ltib (FSL gnome release package ). I am looking for a solution, but at that time I don't know how to proceed. I already started some discussion on that topic in this forum, but perhaps the group "graphics & display" may have the solution !

With standard UBUNTU distribution image, my VGA display works fine (I only have a VGA display connected to the VGA output, I don't use LCD touch screen).

With ltib, nothing happens ! no image, no signal, nothing...

Last boot trace can be found in attachment.

Many thanks in advance for your help.

Best Regards,

Philippe.

I have a "sabre", not "loco", but on my kernel command line, I also have:

video=mxcdi1fb:GBR24,VGA-XGA di1_primary vga ldb=off ard-vga

video=mxcdi1fb:GBR24,VGA-XGA di1_primary vga

try add above to your kernel boot commandline

Hello Al & Hake,

thank you for answering. I tried to add video=mxcdi1fb:GBR24,VGA-XGA di1_primary vga ldb=off ard-vga but, it didn't work.

I tried to replace by video=mxcdi1fb:GBR24,VGA-XGA di1_primary vga but it didn't work.

I guess the problem is more in the ltib setting. Do you know what packages and/or driver I have to use for VGA display output ?

(I attached my last boot log).

Regards,

Philippe

Philippe,

I assume you already halted your Ubuntu distribution image at u-boot console, and viewed the environment variables, where "video=" would be found? If so, what were the options to the kernel? I am using the videos/imxfb driver.

Al,

Yes, on UBUNTU distribution I have :

vga=video=mxcdi1fb:GBR24,XGA di1_primary tve

bootargs_base=setenv bootargs console=ttymxc0,115200 ${vga}

I tried this setting, but no more result.

Where did you specify in ltib setting that you use videos/imxfb driver ?

Regards,

Philippe.

Hello hake,

root@freescale ~$ cat /proc/cmdline

can you try attached image, the "video=mxcdi1fb:GBR24,VGA-XGA di1_primary vga" works for my board.

I tried to replace my uImage by your uImage_mx53_d but it failed. (see trace.txt).

in this case you need uboot

Re: FSL gnome release package and VGA display output ?

philippecavenel — Fri, 04 Nov 2011 10:34:45 GMT

It doesn't boot... which dd command do you use ?

Re: FSL gnome release package and VGA display output ?

hake — Fri, 04 Nov 2011 11:13:09 GMT

dd if=<uboot> of=/dev/mmcblk0 bs=1024 seek=1 skip=1

Re: FSL gnome release package and VGA display output ?

Hello,

Thank you for your help.

After a while, with the last release 11.09 I finally got an output on my VGA display. Now, the mouse is working fine on my X window environment but my keyboard is not recognized, nothing happens when I press on keys....

Do you know if there is a specific configuration for the startx script ? especially for Xfbdev ?

By the way, dd if=<uboot> of=/dev/mmcblk0 bs=1024 seek=1 skip=1 doesn't work for me, I have to specify seek=2 skip=2.

Best Regards,

Philippe.

there are some configs for keyboard support, you can check that in startx scripts.

if skip=1 seek=1 does not work, which mean your SD card can only seek in 512 bytes block.

Re: FSL gnome release package and VGA display output ?

philippecavenel — Tue, 08 Nov 2011 15:11:37 GMT

OK for the SD card, effectively I specify BS=512.

Concerning the keyboard I updated startx script with -keybd keyboard,,device=/dev/input/keyboard0 but in fact there is no keyboard0 in /dev/input, so it can't work. Do you know how to configure keyboard device ? Is it a special configuration in ltib ?

Re: FSL gnome release package and VGA display output ?

hake — Wed, 09 Nov 2011 01:58:40 GMT

what is your keypad input device node? you can use evtest /dev/input/<your device node> to test, then set to the device parameter. No sure it is going to work or not, as the key definitions may need change, you have to look at the xfb code.

Hello hake,

I don't know in fact as /dev/keyboard0 is not present. when I plug in the keyboard I get :

usb 2-1: new high speed USB device using fsl-ehci and address 4
usb 2-1: New USB device found, idVendor=05ac, idProduct=1006
usb 2-1: New USB device strings: Mfr=1, Product=2, SerialNumber=3
usb 2-1: Product: Keyboard Hub
usb 2-1: Manufacturer: Apple, Inc.
usb 2-1: SerialNumber: 000000000000
hub 2-1:1.0: USB hub found
hub 2-1:1.0: 3 ports detected
usb 2-1.2: new low speed USB device using fsl-ehci and address 5
usb 2-1.2: New USB device found, idVendor=05ac, idProduct=0221
usb 2-1.2: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 2-1.2: Product: Apple Keyboard
usb 2-1.2: Manufacturer: Apple, Inc

On device, each time I unplug / plug my keyboard, I get two new devices :

crw-rw---- 1 root root 189, 135 Jan 1 00:43 /dev/usbdev2.8
crw-rw---- 1 root root 189, 136 Jan 1 00:43 /dev/usbdev2.9

(8 and 9 are incremented at each unplug / plug action, next values are 10 and 11 and so on).

I tried to use some other keyboards, but the result is the same, nothing happens when I press on keys. My aim is to recognize all kind of keyboards as I have no idea of what kind of keyboard people will use on my application.

I don't use touch screen, just a VGA display + mouse + keyboard + serial interface to configure the system.

Regards,

Philippe.

the keyboard and mouse are input devices, so you need check it at /dev/input/

Hello,

I selected udev and 'include automount rules' in ltib configuration. Keyboard should be automatically recognized, and it's not the case as far as I can see in /dev/input :

root@freescale /dev/input$ ls -lR

I tried mdev but it failed. I also took a look into bin/device_table.txt and keyboard is not defined. So I am wondering if I have to add it in this file or if the setting should be done somewhere else.

Regards,

Philippe.
