Kernel 2.6.35 very stable, Kernel 3.x unstable

[danielei]

Hi,

I got the olinuxino-micro 2 days ago and I love it !

I had tried Kernel 2.6.35-8-ARCH+ from the link:
MX233-OLinuXino ARCH Linux SD image with WIFI support - Linux Kernel 2.6.35 and completely support for all board features https://docs.google.com/open?id=0B-bAEPML8fwlYUUxaUtsNkZrRk0

it works great, however the USB wifi that I use: TL-WN722N (ath9k_htc) is not supported.
are there any instructions on how to build the image above ? so I can add support for ath9k_htc ?
or even better is there any 2.6.35 image that supports the ath9k_htc driver ?

there are a lot of instructions on how to build kernel 3.x on the web. however I find kernel 3.x highly unstable and it OOPs constantly. I had it working with my USB wifi. but after 10-15 minutes the Kernel crashes ...

bottom line I want to run Kernel 2.6.35 with ath9k_htc support :-)


Thanks !

Can you post the kernel log containing the crash? Does it only happen when wifi is used?

[danielei]

That's a good question. I will try both with and without wifi and post the logs.
Thank you !

guys,
i'm using Jann's version from here: http://sourceforge.net/projects/janncc/files/olinuxino/kernel/3.7.6_EMI_96M/
and I removed the R17 resistor. now it works much better, no oops so far.
I did notice however that the filesystem is very fragile.
i'm kind of newbee, but I think jffs2 is better file system for Flash memory than ext3.
is it possible to install the version on jffs2 ?

Thanks,
Daniel

JFFS2 is used for rootfs stored in NAND flashes. For SD cards we use ext3 or ext4.

What do you exactly mean by: "I did notice however that the filesystem is very fragile" ?

Does ext4 work better?

Hi Fabio,
waoo that was fast response, thank you !
the above is what I mean fragile ...
I flash the image again. start working, installed lighttpd and a few more things, then it crashes, doesn't even recognize ls

thanks !

[Fabio Estevam]

Can you try booting from U-boot mainline with the patch below applied?

[danielei]

Hi Fabio,
i'm very new at this. I just download an image and run. is there an image somewhere I can download that includes that fix ?

Thanks.
