Hello all, I am happy having at least the chance to get OpenBSD running on my machine as I first thought of buying a Raspberry PI. I am pretty new to the OpenBSD and embedded world. So far I have been confronted with working machines out of the box after installing from CD.
Ok. Lets start. The UDOO is a i.MX6 based machine with 1 GB DDR3 RAM and a lot of other stuff. But I don't want to make any advertising so have a look yourself for further details http://www.udoo.org/features/ I was trying to get OpenBSD to boot using the infos available at http://www.openbsd.org/armv7.html Three things I tried: 1. As described in INSTALL.armv7: dd if=miniroot-imx-54.fs of=/dev/mmcblk0 --> booting and nothing happend on the serial line 2. I figured out, that "dd if=miniroot-imx-54.fs of=/dev/mmcblk0" created a partition with the files "6x_bootscript" and "bsd.umg" in it. Then I tried to format the SDCard according to http://www.elinux.org/UDOO_creating_a_bootable_Micro_SD_card_from_precompiled_binaries without installing the root filesystem to the partition but doing dd if=miniroot-imx-54.fs of=/dev/mmcblk0p1 --> booting and again nothing happened 3. Since I am pretty new I had to try a lot of things. I then came across the idea to follow the instructions in http://www.elinux.org/UDOO_creating_a_bootable_Micro_SD_card_from_precompiled_binaries with the exception that I copied "bsd.umg" as "uImage" (according to the description) into /boot. Leaving the filesystem as it is --> booting and it finally happened: ----------------snippet---------------- ## Booting kernel from Legacy Image at 12000000 ... Image Name: boot Image Type: ARM Linux Kernel Image (uncompressed) Data Size: 4954706 Bytes = 4.7 MiB Load Address: 10800000 Entry Point: 10800000 Verifying Checksum ... OK Loading Kernel Image ... OK Starting kernel ... --------------end snippet-------------- I had to learn, that UDOO itself is not equipped with anything close to a bootloader but takes the first thing it finds on the SD card. I learned, that this has to be the U-Boot image. So far so good. I took the bsd.umg that I found out is the same as http://ftp.openbsd.org/pub/OpenBSD/snapshots/armv7/bsd.rd.IMX.umg and this is the compressed RAMDisk kernel, where the compressed filesystem contains the installation tools. Now my question: Why does it hang after printing "Starting kernel ..."? Is there any output that I can not see due to changed serial line parameters (speed != 115200)? HDMI isn't also generating any output. What do I have to do in this case? Or can it be that, the boot process suddenly stops there? Can you suggest me any further reading or any hints how to proceed? Thanks in advance. Cheers, Willi
