The newest kernel 3.4.90+ is no longer booting

[fab]

Hi,

I tried to build the newest kernel 3.4.90+, and got this error when booting the A20:
(Seems to be an error related to the cedar module...).
So I reverted back to 3.4.79+ which is working well.

Have you reported it to wherever you got that kernel?  (Where did you?)

Yes this issue was reported back to the linux-sunxi on the google groups.
The kernel was cloned from the sunxi git hub.

OK, at least now they can put it on the To Do list.  It's optimistic to try bleeding edge...

Thanks for sharing

Is there any bug to track ?

Is there any commit to revert temporally

I am also looking for static .config file for sun7i-a20-olinuxino-micro
(builtin features no modules) ...

will share it if needed

You could try git bisect if keen to find what happened.

Hello,

with

Code Select Expand

git clone https://github.com/linux-sunxi/linux-sunxi.git I took the 3.4.90+ kernel, that's don't boot (as reported by Fab).

But I don't understand how to obtain the "old" 3.4.79+ version (I have it on my home PC), but not at workplace...

In http://linux-sunxi.org/Linux_Kernel is not reported
using

Code Select Expand

git clone -b sunxi-3.4.79 --depth 1 https://github.com/linux-sunxi/linux-sunxi.git

give

Code Select Expand

Cloning into 'linux-sunxi'...
warning: Could not find remote branch sunxi-3.4.79 to clone.
fatal: Remote branch sunxi-3.4.79 not found in upstream origin
Unexpected end of command stream

Any idea?

Thanks in advance

Best regards

Sorry, my bad

kernel 3.4.90+ boots
I used USBcom debug and I'm able to connect with the board.

I made some compilation error 

Nevertheless,  is there a way to obtain older kernel version?

Thanks and sorry again

[JohnS]

Quite a few pre-built are on Olimex site / this wiki / linked from them.

You can download and build any version over the last many years if you wish, too.

Thanks for your reply John.

I know I can download a20 image from Olimex a20 wiki, but I need the kernel sources.

Could you please provide a link?
I'm searching on github but without success.

Thanks

[JohnS]

Olimex provide them and you can go on linux-sunxi wiki

You need to get a specific revision in the github. All minor versions are in the same branch 3.4

For a list see here:

https://github.com/linux-sunxi/linux-sunxi/releases

Thank you very much jlucius!
That's exactly what I need!
