[opensuse-arm] Kiwi problem for raspberry pi image
Hi, Finaly, I got an image from OBS for Raspberry Pi (armv5 image) but I have the following problem. All boot files (kernel image, etc.) are in /boot folder from ext3 partition, not in FAT32 boot partition. Any idea why? So that we could fix it?

Do you really need the /boot folder to be vfat? Couldn't you live with a FAT jump partition that contains u-boot and then boots the kernel from an ext3 /boot? That's how we boot the chromebook, and it makes life a lot easier. Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

How would one set that up within kiwi or whatever? I think that may be the solution to getting the Snowball working. The only working image I have is from over a year ago. -- Andrew Wafaa IRC: FunkyPenguin GPG: 0x3A36312F -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Check out the chromebook image description and kiwi patch. You need a "jump partition" which kiwi leaves free for you to use. Then you create a special jump FS in your u-boot-install script.

Raspberry Pi must have a FAT partition with a binary bootloader which init the board and loads directly the kernel image. So, FAT boot partition is mandatory... :( RPi has lots of proprietary/closed soft which does not help to hack. Guillaume

Not sure I understand what you mean. Rom bootloader loads closed binary bootloader from FAT partition to RAM and then this bootloader is looking for kernel image on the FAT partition, so we need to have it their. I thought what was done with OMAP at the beginning was a FAT boot partition which was mounted on /boot folder from ext3 partition. Guillaume

Nonono. The Rom bootloader loads the closed source binary loader from a FAT partition. This bootloader looks for a binary to execute from a FAT partition. That binary could just as well be https://github.com/gonzoua/u-boot-pi/tree/rpi. That u-boot could then read a boot.scr from an ext3 partition and load the kernel+initrd from an ext3 partition. Hence, /boot can be ext3. You need a jump partition with * closed source binary bootloader * u-boot
I thought what was done with OMAP at the beginning was a FAT boot partition which was mounted on /boot folder from ext3 partition.
On OMAP, we are completely FAT-free by now, since we can store the intermediate loader in a hard sector offset on the SD card. Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

There's no need to play with it for end users. Also, u-boot supports graphics in general, so eventually I would imagine there will be a graphical u-boot that users can then play with again.

Be careful, you can brick your device if connecting the UART pins directly to a serial cable (wrong Voltage). You need a level converter (e.g. MAX 232). I am writing this just for safety. You all know that, i assume. Johannes -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
Hi, friends. I suggest to use the MAX2323 as this chip can be operated with 3.3 V available e.g. from pins at the Raspberry Pi. It operates with 100KHz, the capacitors should have a value of 100 nF. I draws approx. 6-8 mA at idle. Regards Edgar, DJ3PU, from Munich Am 28.01.2013 18:03, schrieb Johannes Poehlmann:

This bit you would have to do yourself in the u-boot-install script.
Is there some value added with u-boot except this workaround? Otherwise, we will get a longer boot time for "nothing".
The biggest value added is that we have a boot script that's generic across the board with a /boot file system that is proven to work well with all our scripts.
I thought what was done with OMAP at the beginning was a FAT boot partition which was mounted on /boot folder from ext3 partition. On OMAP, we are completely FAT-free by now, since we can store the intermediate loader in a hard sector offset on the SD card.

Why would we want to do it differently from every other RPi distribution out there?

No, we do it differently because the point of a distribution is consistency across the distribution. If you come from a beagle board, you want to be able to work with a raspberry pi. Chances are a lot less that you come from Debian on raspberry pi to openSUSE on raspberry pi. If you are on Debian, we lost you already ;). Alex
And we'd even waste some boot time :-)
That time should be negligible. Alex -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org
