I tried the newest XFCE Raspberry Pi 4 images for openSUSE Leap 15.2 and Tumbleweed. Both are extremely slow to start. I did not have enough patience for Leap 15.2 to see it finish with a log screen, so abandoned that test and continued with the test of Tumbleweed. There are several error messages during the boot process to explain why it takes so long, but even loading the final linux image takes minutes. Below is what I did catch during the start of the boot process: ------------------- U-Boot 2020.04 (Aug 09 2020 - 19:41:12 +0000) DRAM: 3.9 GiB RPI 4 Model B (0xc03112) MMC: mmcnr@7e300000: 1, emmc2@7e340000: 0 Loading Environment from FAT... *** Warning - bad CRC, using default environment In: serial Out: vidconsole Err: vidconsole Net: eth0: ethernet@7d580000 PCIe BRCM: link up, 5.0 Gbps x1 (SSC) starting USB...

Hi,

RPi4 is now tested in openQA: https://openqa.opensuse.org/tests/1451651 And there is no such problem.

Could you try another uSD card, and/or another RPi4, maybe?

Once the system is up, it behaves normal/fast. I don't have another RPi4. I could try another uSD, but considering it is fast when it is up I have no hopes. The uSD i use now is a Sandisk Ultra with 128GB and an encircled 10. Also putting the image on it is fast.

...

Cheers, Guillaume

Another observation is that another uSD with Raspbian is working normally. Boots in less than a minute. So it is NOT the RPi4. openSUSE shows a number of tests on different partitions, before it finds a bootable image and gives an error message that an image has not been found. Will try the uSD with Raspbian with openSUSE. -- fr.gr. member openSUSE Freek de Kruijf -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Hello, I just downloaded the image for my Pi as well and I also recently watched Peter Chubb's from 2015 talk regarding his experience and with SD cards and Linux filesystems. https://www.youtube.com/watch?v=K3zb6p0thQU There he notes that most MCUs and firmwares work with a 4M alignment size. Hence the general recommendation appears to be to keep the MBR table in that first 4M block and align the first partition start to address 4096. This seems to be what the official formatting tool of the SD Association does. When I flashed the current Tumbleweed JeOS image to my SD card with dd I noticed that the partition starts at 2048. Other partition start addresses do not appear to fit into the physical 4M block size either. Swap starts at 133120 (divided by 4098 equals 32.5) and does not align, Root at 11571120 (divided by 4098 equals 2823.60...). So hence to improve performance the alignment of the partitions on the image should be fixed. The question is how. Best regards Tamara On 29/10/2020 09:51, Freek de Kruijf wrote:

There is KIWI option

I tried the uSD, which works good with Raspbian, with the Tumbleweed JeOS images from Snapshot20200918 and Snapshot20201022 and both show the same behavior as described earlier. Did put Raspbian back on the uSD; works OK.
