AT91SAM9261-EK: linux4sam jffs2 image and custom kernel

fabatera · **Joined:** Tue Feb 10, 2009 3:24 pm **Posts:** 11

Hi,

I'm working with AT91SAM9261-EK and I'm having some problems whit jffs2 downloaded in http://www.linux4sam.org/

I'm trying to use their jffs2 image with my custom Kernel (because site's Kernel image is .bin and I can't change it) without success.
Following site's examples, everything works fine. My custom kernel with nfs is fine too. But when I join jffs2 image + custom kernel I hed the errors listed below.

I read a lot of topics about similar things in this forum and googling.

Somebody could help me?

regards
Fabiano

Check weather you are passing a correct console=/dev/ttyS0 name. i.e. check if it is ttyS0 or ttys0 or tty0 etc. Also check if you have enabled the console and long arguments support in the kernel configuration

Thanks for answering.

I had changed compiler. Now it's booting ok.

Its good that I is booting. But just changing the compiler is not a solution to the problem. Did u try to find what was the problem,If yes can u just share it out so that it
can be useful to others as well.

BR,

I think it's because the filesytem is EABI and the old compiler was not compiling with EABI option.
But I'm not sure. The filesystem's owner didn't inform this.
