Hi,

 

Seems that it913x driver is broken on solo2. if it913x card in inserted during boot it stops booting. If it is inserted after module crashes during the attempt to attach frontend. Same device works fine under x86 linux.

[littlesat]

Hopefully it is not related on the relativily older kernel vu is using....

[dmarion]

It is not. I just tried on kernel 3.3.7 and it works. solo2 uses 3.3.8.

 

Any idea what to do?

[macnuts]

The same problem on  my new Duo2. It was working perfectly yesterday with OpenPli 3.0 on DM8000.

[ims]

It is not brocken it913x, it is brocken image.

 

Same it is for XP1000 from nightly build image >= 20131202. I wrote about it and similar log I sent to D.

 

There must be flashed 20131201 again (unfortunately, is not on web yet, but it is a last working nightly build) and then with "update software" get last status, as i made it for XP1000 (with it913x) and I made it for one DM800SE, when i tried make free flash on weekend. I had not power try it on vuultimo too.

Unfortunately, for DM800SE each next software update ending as "bus error" => I go back to 3.0 on both DM800SE.

 

Problem is, that there are not available feeds (net unreachable - for some time) and it seems, that some is not downloaded. Autoinstall must be run manually too after flash.

[macnuts]

Where can I get 2013-12.01 build for Duo2?

 

After that, is it safe to opkg upgrade to get the latest version and it913x will be still working?

 

I've just checked that it913x works perfectly with the latest image from VU+ (after installing firmware package "borrowed" from openpli). I've noticed that corresponding VU+ packages are in r1 and on openpli they are still r0.

 

Regards.

[macnuts]

Thanx for a hint, ims.

 

I found 20131018 image, flashed it, and made online update. My it9135 is visible but has issues (I've started another thread on that).
