Re: Kernel 3.2 for bubba3

Would one of you be willing to provide a summary of **all** the steps needed for this in a single post (or a Wiki How To?), as well as saying why you'd want to do this and what it achieves for those of us watching with more excitement than understanding? :-) Well "this" is for now a work-...

Re: Kernel 3.2 for bubba3

I wonder if for safety it would be possible to have packages dependencies set up just like Debian, where you can have several kernels installed in parallel. In case something goes wrong at an update, it would allow to go back to a previous version. Short answer : no ; there are at least two reasons...

Re: Kernel 3.2 for bubba3

I've compiled the newest 3.2.62 version of the kernel. The links of the first post are updated. This version is the first to be compiled directly on a b3 device (FYI 3 hours compilation).

Re: uboot update needed.

My python script is not very reliable and even worse I cannot make it work anymore myself. However recent versions of u-boot ships a little program for this task, kwboot, which works well at least for me. It is included in the Excito version, so You just need to compile it on the computer with the s...

Re: uboot update needed.

I opened a new thread in the development forum to discuss about kernel upgrade, as it is an other subject. You can find it here with links to a working 3.2.61 kernel :) .

Kernel 3.2 for B2/B3

Hello everyone, After wheezy install image and u-boot update, I managed to patch and compile a 3.2.61 kernel package for the bubba3 and the bubba|two. I choose this version because it's the one debian uses in wheezy. It runs apparently fine on my b3 and on my b2, so I need some volunteers to test it...

Re: uboot update needed.

In any case, if the u-boot from MouettE can be verified and upgrading to it can made to be an official Excito release, this would definitely open up the possibility to create a new bubba-kernel of version 3.x and change distribution without loosing the Bubba OS front end. I guess that would make a ...

It should be reasonably safe ... But maybe someone else with serial access should try it first.

Short answer : No
You need some logic to convert TTL signal to RS-232 (and then to USB if you don't have a serial connector on your PC).

Re: uboot update needed.

I would really much like to understand (and fix) this MAC adress resetting problem. Any help would be welcome! After digging into the source code of u-boot I figured out why the net links weren't properly initialized in u-boot and how to fix it ; you need to edit the file include/configs/bubba3.h a...

Re: B2 rev RD serial access

I have written and tested a few days ago a script which executes this procedure on the Bubba 3. I have been able to run a u-boot image from the serial port and it works quite well. I will soon post the details on the dedicated u-boot thread. However I don't have any clue about doing that on a B2. I ...

Re: uboot update needed.

You don't need the serial console to access the u-boot environnment. You can use uboot-envtools package with proper configuration (see http://forum.excito.net/viewtopic.php?f=7&t=2715)

However if you mess your environment and cannot boot anymore, you'll need a serial console to correct it.

Re: Building Custom kernel v. 3.2.51 for Bubba2

A good start would be to copy the bubbatwo_defconfig to linux-3.2.51/.config and run make oldconfig. Then you can run make menuconfig to adapt if you wish. Dont't forget to set the variables ARCH and CROSS_COMPILE before runinng the make commands. Good luck and please keep up posted of your progress.
