Hi Otto,

I did everything according to the tutorial and when I power ON the riotboard

everything looks to run properly. On serial terminal I can see how everything is being

loaded. But from the HDMI display I can really do nothing.

Just can see small linux penguin on left top corner and no prompt line.

It doesn't react on the keyboard while on serial terminal I see system detecting it on USB when plugging and unplugging.

Did I miss some configuration.

Thanks for help

Hi Otto,

Thank you for your tutorial that does help me a lot.Follow you instructions, everything goes well, and when finishing the fourth part, the second LED go into hearbeat mode and starts blinking.But I meet a problem, the display can't receive any signal via the HDMI. What need I do to make it?

Expect for your help.

Thanks

Hi Otto,

Thanks for your response.

For my application, i need an RT kernel so i build from scratch a kernel with RT patch

I configure it with imx_v7_defconfig default file

Now all device works fine

I suppose the problem is in your riot_defconfig file.

Thx

Hi Otto,

Very good tutorial !

I flash the RiotBoard with your kernel and the rootfs debian wheezy.

During the boot, all seems OK

But when i wanted to use the ALSA device, i can't

I can see SGTL5000 device registered and one ALSA device listed.

But when i want to record on hw:0,0 input capture i have an error

pcm_read error.....I/O access error....

What is the problem ?

Thx
