Image build problem for Lime2

[alexparser]

Hi!

I try to build the image Lime2_Ubuntu_trusty_3.4.111 for Lime2 from Armbian repository.

For this process I use this documentation -  http://www.armbian.com/using-armbian-tools/

After success finish of compilation process, I write image on the SD and try to boot.
After 10 sec of start the booting I get the black screen.

Its image work fine Lime2_Ubuntu_1.6_trusty_3.4.106

Can you help me solve the problem?

How long did you wait at first boot and have you attached network?

How long did you wait at first boot and have you attached network?

I waiting about 10 min and no network.

 

This images have same problems with a boot:

Armbian_5.07_Lime2_Debian_jessie_3.4.111

Armbian_5.07_Lime2_Ubuntu_trusty_3.4.111

Armbian_5.07_Lime2_Ubuntu_trusty_4.5.2

Only one image was boot (Armbian_5.07_Lime2_Ubuntu_trusty_4.6.0), but without network.

 

Any ideas??

Today I test a new images:

Armbian_5.10_Lime2_Ubuntu_trusty_3.4.111
Armbian_5.10_Lime2_Ubuntu_trusty_4.5.2

Also boot failed, after the message 'Starting kernel ..' board is shutdown.

 

Maybe you can give me recommendations how to fix boot problem?

http://forum.armbian.com/index.php/topic/729-olimex-lime-a20-wont-boot-armbian/?hl=lime2#entry5492

According to this it should work and problems should be gone in latest build.

 

My Lime 2 is busy serving this forum so I can't do a quick test to see if this can be reproduced. 

 

Try build dev kernel which also contains dev u-boot.

Thanks Igor!

I build dev kernel 'Armbian_5.10_Lime2_Ubuntu_trusty_4.6.0-rc5' this work fine, but dhcp client can't get ip.

Small change in /etc/network/interfaces fix the problem.

auto eth0
iface eth0 inet dhcp

Other problem, this build does not have I2S patch.

How I can do build with I2S supporting?

[Igor]

I2S is supported only in legacy builds AFAIK. I made one legacy build - I hope this one works:

[Igor]

I made a test on Olimex Lime, the one with 512Mb and EMAC and it was also not booting due to broken U-boot. I made a walkaround fix and now it's booting fine. This probably affects other Olimex boards too.

Thanks Igor for last build,

I tested him, boot is ok, I2S worked.

But I found one problem with playing sound, files 192k playing with distortion, sound intermittent.

CPU load less 10%, RAM 50MB.

This problem may be with system interrupt or with I2S driver?

Other bitrates: 44k, 88k, 48k, 96k work fine.

Build Lime2_Ubuntu_1.6_trusty_3.4.106 playing 192k perfectly, but have other problem.

Any ideas?

Not really, don't know for any quick solution  There were many fixes to the I2S driver in last year. To find out where is the problem ... adding patches step by step, testing, talk to driver contributor, @Nikkov.

[alexparser]

I wrote message for Nikkov about this problem.

One more question, this problem may be on the OS side?
