PXE Boot a Beaglebone Black via U-boot

Embedded Linux Discussions
1

Hi there,

I’m trying to setup a network booting Beaglebone Black Rev. C (4GB eMMC). I have a working network setup, and I’m using PuTTY and a serial com to work with U-Boot. I’ve tried so many guides, all that just seem to fail me and deliver no results. I also can’t seem to find any real resources on PXE booting with U-boot and Beaglebone as a whole. Or I’m seriously missing it somewhere.

I built a custom image for this bone with the image building scripts from https://github.com/beagleboard/image-builder which uses Robert’s https://github.com/RobertCNelson/omap-image-builder

Next I unpack the tar file and used the vmlinuz-4.19.79-ti-r30, initrd.img-4.19.79-ti-r30 and am335x-boneblack.dtb in the pxe file like so:

label kernel-bbb
kernel vmlinuz-4.19.79-ti-r30
devicetree /dtbs/4.19.79-ti-r30/am335x-boneblack-uboot.dtb
initrd initrd.img-4.19.79-ti-r30
append console=ttyO0,115200n8 root=/dev/mmcblk1p1 rw rootfstype=ext4 rootwait coherent_pool=1M net.ifnames=0 rng_core.default_quality=100

U-boot gets the pxe via the network and when I use pxe boot. The process starts and places everything in the correct RAM address, which I assume it finds in uEnv.txt already in the eMMC (I flashed the eMMC with a different custom image build also using the image-builder scripts).

However, then everything is done, and the kernel needs to starts, nothing. The console just shows “Starting Kernel …” and after a couple of seconds the bone resets and U-boot starts spitting out the default booting info.

Any help?

@HHayman, I’ve never used the u-boot pxe scripts, we are probably missing something.

But every factory image contains a “/nfs-uEnv.txt” file, to do tftd/nfs boot, so if you rename this as “/uEnv.txt” it’ll use the built-in tftpd path of u-boot.

For reference here is the “/nfs-uEnv.txt” example:

##Rename as: uEnv.txt to boot via nfs

##https://www.kernel.org/doc/Documentation/filesystems/nfs/nfsroot.txt

##SERVER: sudo apt-get install tftpd-hpa

But looking at your log:

I’d expect to see “more” kernel noise, as “quiet” is disabled and the console is enabled.

Thank you so much so the timely response.

I left out quiet for the purpose of seeing more info on what is happening, but that’s my problem. Nothing is happening. I based my attempt on the PXE boot via U-Boot on the article:
https://wiki.radxa.com/Rockpi4/dev/u-boot/pxe ,

and the arguments for the kernel based om what U-Boot spits out to the serial console as it boots on just a clean power-on and run through. The arguments I provide and what the article uses are little bit different. Not sure if that makes the difference (hoping it’s the Pi vs Black style difference for providing arguments to the kernel).

I’m aware of the nfs-uEnv.txt rename situation. To be honest I’m a little nervous as I’m totally new to the NFS side of things. I was hoping you might know of a way, or if there was a way to simply unpack the output of the image building scripts in a folder(directory) and just tell U-Boot to boot everything from there. But I think that’s wishful thinking. I have a feeling there might need to be some tinkering/tweaking.

Thank you for the NFS reply. I’m going to be attempting it now. My previous try with the nfs/nfsboot (can’t remember exactly) in U-Boot lead to nothing as well.

Will try that now with the nfs-uEnv.txt rename work around now.

Thanks,
HS Hayman

@RobertCNelson I tried the NFS-boot method, even tried a few guides on it too. I keep getting U-Boot to do it’s thing, and then having the kernel panic leading to the board to reset. Could it perhaps be the kernel build (or downloaded) by the scripts that might not be configured to boot over the network via varies options? Or am I still missing something here?

Thank you in advance,
HS Hayman

@HHayman, sorry for the delay, took awhile to setup nfs and rsync the image, i used the same kernel image you had tried using with the buster iot image…

While I got it to boot, connman wasn’t happy so i can’t ping out… ( i can ssh in just fine, so it looks like the dns just needs to be updated…)

@RobertCNelson Again, apologies for the wait. I had some technical issues with the network and Linux machine. But I marked the NFS post as a solution, the rfs mounted correctly after I finally found my typo in the exportfs config file. The Beaglebone boots complete over the network, I however did spent a lot of time failing. Got the first successful boot moments again, Busy rebooting the bone in the backgound. Seems to be working just fine.

One problem I had, was when I sent the vmlinuz and the dtb, both transfer via tftp, however I still had the kernel panic. I deviated a little from your (nfs) uEnv.txt and added the arguments, which seemed to "fix"the boot, as it’s running smoothly now. I’d append it to this post.

Thank you so much for the help and patience. I’ll still try and figure the PXE approach out, but for now, I have all I need.

Kind reagrds,
HS Hayman
