Synchronous abort handler in boot for le potato

Software
1

I need an SBC for my duet3d control board and since I’m not using a raspberry pi, I need it to run armbian. I tried both a samsung evo and an evo select but I cannot get past uboot. Normally I’m assuming this is an armbian issue but for some reason my firewall keeps blocking armbian’s pages so I can’t go there for help. I’m hoping there’s some help I can get from here instead.

Using UART, I was able to pull the following from boot up of the potato:

We don’t really support Armbian here outside to very simple stuff. However, their images in the last few days have been buggy so that is probably why. We do recommend that you use our images instead of Armbian due to numerous tweaks we have in our images over what Armbian provides.

I may have no choice, although there are no directions for non-armbian builds with Duet3d boards in SBC mode.

4

After taking a brief look at it, it seems the only thing you need to do on our images is enable SPI:

sudo ldto enable spicc spicc-spidev 

#test that it is working and if it works, merge it permanently

sudo ldto merge spicc spicc-spidev

The rest of the instructions look fairly standard.

Wow, I didn’t even link to the article. Thanks for going out of your way to be so helpful. I’ll try this again tomorrow.

Let us know if you encounter any issues with the instructions. We can help you debug it so other people can use this as a reference if they want to do the same.

Is sd_uhs=1 enabled on the raspbian images? Where is that setting? The guide mentioned “DCS uses SPI buffer sizes of 8KiB whereas the default Armbian buffer size is limited to 4KiB.” What is it set for in your raspbian builds? How can that be changed? How do I create a password for the raspbian image from a Mac? the openssl syntax seems different.

  1. SD UHS
  2. Test to see if it works with the default SPI settings. The 4K buffer is a Raspberry Pi thing. You can set buffer size for spidev’s module using:
sudo rmmod spidev
sudo modprobe spidev bufsize=8192
#permanent
echo "options spidev bufsiz=8192" | sudo tee /etc/modprobe.d/spidev.conf
  1. The password thing applies for Raspbian Lite images only. If you are using the desktop, it does not apply as there’s a GUI on startup to set it. You have to Google how to do it on a Mac because we don’t use anything Apple.

I can’t SSH in. connection is refused. I did the openssl step on a linux machine. UART shows its booted and waiting. I can’t log in via UART either, it wont take my name and password, nor pi:raspberry, nor root:1234. nothing

What image are you using?

11

I am trying to go with raspbian lite.

There’s a bug with the userconf service in the Raspbian image. We have updated the image generation code and out CI will generate new images in 24 hours. For now, configure the first user and ssh using the GUI setup.

the new image doesn’t resize the partition. UART is also not outputting anything anymore.

Fixed the issue, the new build will be on the servers in approximately 2 hours. For your existing image, you can run the follow to fix it:

sfdisk -d /dev/mmcblk1 | sed "s/size=\s\+[0-9]*,\s\+type=83/type=83/" | sfdisk --force /dev/mmcblk1
partprobe /dev/mmcblk1
btrfs fi resize max /
