ESPRESSOBin Board not booting due to kernel panic if SATA connected


Recommended Posts

Hello every one,

 

I own two ESPRESSOBin boards V5.

And to both I attached an XCSOURCE® MiniPCIe Sata3.0 AC696 extension card via MiniPCIe.

This is the link to amazon: https://www.amazon.de/dp/B06XRG2TGV

 

I tested several images from https://www.armbian.com/espressobin/#kernels-archive-all

Unfortunatelly all the old images have been deleted last week, so I could not continue testing.

 

Tested Kernels 8 weeks ago + the latest two this week:
- 5.10.09-mvebu64  #21.02.0-hirsute (trunk) <-- works not
- 5.08.18-mvebu64  #20.11.6-bionic <-- works not
- 5.08.18-mvebu64  #20.11.3-focal <-- works not
- 5.08.18-mvebu64  #20.11.3-bionic <-- works not
- 5.08.06-mvebu64  #20.08.2-focal <-- works not
- 4.14.135-mvebu64 #19.11.3-bionic <-- works

The boards boots up if I don't plug in any SATA HDDs into the extension card.

 

I hope this helps. If you need any other information just let me know, I'm absolutely willing to help. But please be aware that I'm a software developer coming from windows trying to get into linux. But I have no clue of kernel patching/compiling etc. Sorry!

 

Thank you very, very much in advance! You're doing an awesome job.

 

Sincerely Rötti

We have no time and absolutely no budget to cover bugs on this very buggy hardware. Officially Armbian don't have any maintainer(s) for this board anymore, so its basically a community supported, as is. @Pali is trying to bring up mainline u-boot support and that's about it. Don't know how far things are and if upgrading u-boot helps in this case. It's only alternative, so worth trying.

 

This is just a bug like any other - moved to bug tracker forums.

@RöttiThis looks like an AHCI or PCIe issue. Please report bug to the linux-ide@vger.kernel.org mailing list where are more SATA/AHCI developers and could help you to debug issue. Maybe it is also A3720 related PCIe issue, so send me an email I can provide you a A3720 PCIe patch which could fix some stability issues.

Hello @Igor, hello @Pali

 

thank you for the information and thank you for moving the topic into the right forum.

Again thanks for that information, but I'm still here to get Armbian run on even this buggy hardware ;-)

If you expect me to do more than writing to the linux kernel mailing list and the EspressoBIN forum, please point to the right direction and I will help.

For example, do you have any backups of all previous images? If so, where can I find them. I'd like to try all images to narrow down when the bug has been introduced.

 

Update:

@Pali Thank you so much for pointing me to this mailing list. This was exactly what I was looking for. I wrote them a mail and will report back as soon as there are new information being revealed.

Furthermore I added a post to the EspressoBIN Forum, which is currently on review. As soon as it's being approved, I'll link the post here.

 

Thank in advance.

Hello @lampra,

 

thanks a lot for this awesome hint! I have been using this link: https://redirect.armbian.com/region/EU/espressobin, on which I found the archived images, but were removed approx 2 weeks ago.

Feeling so dumb, this archive-button is so big, that my brain based ad exclusion just removed it ;-)

 

This is going to help a lot! I'll be able to find out in which exact version the bug has been introduced.

@Rötti Are you able to boot from the onboard SATA? (not from the extension card via MiniPCIe).

I couldn't boot from SATA a year ago so I gave up and used openwrt but I would prefer using Armbian (I can't test newer releases as it is installed far away from home).

@Pali I posted the problem to the ide-linux kernel mailing list as proposed, but unfortunately received no answer.
Here is the link: https://www.spinics.net/lists/linux-ide/msg60178.html

 

Furthermore I were able to narrow down the kernel versions and exact image version of Armbian where it broke:
Armbian 19.11.3 with Kernel 4.14.135 <- last version which was working
Armbian      5.65 with Kernel 4.18.16   <- first version which is not working

@lampra I'm not booting from sata. I'm still booting from SD-card, but get a kernel panic by mere plugging in the SATA cable via the pcie sata-controller. I'm sorry I'm not having further information about your issue.

Do you mean loading firmware directly from SATA (without NOR)? Or loading firmware from NOR and only loading kernel from SATA?

 

Last week I updated documentation how to build & store fimware to SATA disk (needs special partition), see: https://trustedfirmware-a.readthedocs.io/en/latest/plat/marvell/armada/build.html (search for "SATA device boot")

 

And last year I have tested that U-Boot loaded from NOR is able to access SATA disk and load kernel from it without need to use uSD card. If it does not work post U-Boot output from serial console.

I have looked at email which you sent to mailing list https://lore.kernel.org/linux-ide/cbbb2496501fed013ccbeba524e8d573@posteo.de/T/#u and you did not provide all / enough information. At least output from lspci -nn -vv is needed to correctly identify type of your PCIe SATA controller. Also there is missing dmesg output between [ 0.000000] and [ 3.694604] period. Please provide these informations (to mailing list).

Hi Pali,

 

deeply sorry for the long delay, but we struggled with some Covid-19 related issue within the family.

I Added the lspci -nn -vv output to the mailing list.

But I could not find the according dmesg output. After unplugging the SATA cable and rebooting I were able to login and looking at /var/dmesg but I couldn't find any information from the time around the crash.

@Rötti: Also please boot linux kernel with console=ttyMV0,115200 earlycon=ar3700_uart,0xd0012000 command line option so output on UART would contain full boot log.

 

As you can see in the output below I already have these parameters in the console variable.
Is there a special way to boot with this parameter, or is it automatically used
when I call 'boot' because of 'set_bootargs' which contains 'console' already?

If you call 'boot' command it executes 'bootcmd' variable. And if you trace 'bootcmd' from your printenv output it can be clear that 'set_bootargs' is not called in this path.

 

Seems that your 'bootcmd' ends in 'boot_a_script' variable which loads external boot script (from uSD card?) and this one boots kernel. Script can do anything, including setting new variables, etc. So it may be possible that this script set or does not set 'console' into 'bootargs'. You need to investigate it.

 

You could try to unset 'console' (= booting without console=ttyMV0,115200), maybe it helps. For recent kernels this console should not be needed.

This is issue in ASMedia SATA controller card, not in Espressobin PCIe. Card announces support for 512 byte long PCIe packets, but when PCIe controller is configured for such long payload size then card cause system crash. We have reproduce this issue on other platform too.

 

Marek sent kernel patch which adds quirk for this ASMedia SATA controller to set maximal payload size to 265 bytes https://lore.kernel.org/linux-pci/20210317115924.31885-1-kabel@kernel.org/T/#u and which should workaround this issue.

Hello Pali,

 

as said in the kernel mailing list: Thanks to you and Marek.

What I'd like to ask is, how does the workflow or the next steps look like?

 

I mean, how long does it take to get the patch into the kernel (weeks, month)?

How likely is it to be rejected?

As soon as there is a new Kernel, will there be any nightly builds from armbian side?

Are those changes flowing into Armbian directly or are there backports?

 

Thank you in advance.

I mean, how long does it take to get the patch into the kernel (weeks, month)?

 

It would be merged either into next -rc version or into next mainline version (depends on how maintainers decide). See https://www.kernel.org/ for current released versions. And see https://www.kernel.org/category/faq.html for question When will the next kernel be released?

 

After it is merged into rc or mainline version then this patch (because it is marked as bugfix) would be automatically included also into all longterm versions.

How likely is it to be rejected?

 

Unlikely. In case it is rejected it would mean it is needed to update this patch (fix issues) and Marek or me will do it.

 

For rest of armbian related questions ask armbian people.
