So, I started trying to build a minimal Yocto build (version 6). Got everything setup following the instructions. I started building (bitbake core-image-minimal) and it went for quite a while, but then I started getting timeouts.
line 581, in connectProcessServer
** sock.connect(os.path.basename(sockname))** BlockingIOError: [Errno 11] Resource temporarily unavailable
and this: #BB_HASHSERVE = “auto” #BB_SIGNATURE_HANDLER = “OEEquivHash”
And i get slightly different results but the effect is the same. A timeout error.
The IP address it is trying to get to is 198.145.29.33., which doesn’t show a rDNS entry.
I am also getting this warning: oe-core/build/…/layers/meta-freescale/recipes-multimedia/imx-codec/imx-codec_4.7.2.bb:63: DeprecationWarning: invalid escape sequence .
It’s been more than a year since I built yocto verdin imx8, but I pulled everything local and built from there.
I hope they haven’t changed the entire build process to require remote fetching. I’ve seen a lot of complaints about their Web site and time outs. I pray to God they aren’t using anything from Amazon because AWS has multi-hour outages on a regular basis.
I don’t know if I can share the instructions I had to write for that client, but have you tried checking out the entire git repo and building local? I had a 6TB WD Black when I was doing it so space wasn’t really an issue for me.
First of all are you trying to build from our Reference BSP or from TorizonCore? Which instructions are you following?
I see you’re trying to build core-image-minimal which isn’t one of our images, did you intend that?
As for the timeout issues I can’t say I’ve seen anything major recently just minor network hiccups that go away upon a retry. Are you able to access the timed-out URLs from your network in the first place?
Hi @jeremias.tx ,
Yes, I am trying to do a Yocto build of minimal size, and then work my way up from there. I want to see what devices show up in this build, and then add my program to see what else I need.
At this point, I found that if I upgraded the tools to the latest, it built very fast and is complete. So now I am trying to deploy, but I can’t get the board to mount as USB drive. It keeps coming up with an error.
I have built core-image-minimal-verdin-imx8mp-20230615231906-Tezi_6.3.0-devel-202306
15231906+build.0.tar tarball and i want to be able to program it.
Hi @jeremias.tx ,
I can’t seem to get the easy installer to mount my flash drive. Is there a particular format it needs? It just comes up with an error. I do also have the reference version as well, so if the core version doesn’t work and I try the reference version.
Hi @jeremias.tx ,
It turns out that the name of the tar file was causing the drive error. When I extracted the tarball to a folder with a short name, Easyloader found it and placed it on the list.
So, my next trick is to change the pinout to add a second SPI device. I did it with a Torizon build, but how do I do that with the yocto build? It says in there that you guys don’t keep files for that. I currently have the reference Yocto build on my board, and I can see the spidev1.0 there as expected.
So, my next trick is to change the pinout to add a second SPI device. I did it with a Torizon build, but how do I do that with the yocto build?
Well the core concept is more or less the same. You would still do the same/similar device tree changes you did in TorizonCore, but you now need to integrate your changes into your Yocto build, basically modify the default kernel recipe in order to incorporate your changes.
Hi @jeremias.tx ,
So, I read something recently on the site that said you can apply a change to the current build.
I am assuming that the change to the device tree is the same between the reference yocto build and Torizon default build since all the devices seem to be there. Can I just deploy that change to the Yocto reference build? I already have a device tree change working that adds the extra SPI to the device tree. It would seem that the device tree is separate from the Linux build, as it is just setting up the mux and output changes. Is this a correct assumption?
it says to clone a directory but add in the correct branch name. However, when I go to the repository, there are no branches here. It appears that this is broken here.
I mean yes, did you see the documentation I referenced in my previous post? There’s a section in there about how one could incorporate kernel and device tree related changes. It outlines a simple example though, so you may still need to reference Yocto documentation for more complex scenarios.
Hi @jeremias.tx ,
yes, I got to the point that you compile the actual dtb (in my case imx8mp-verdin-wifi-dev.dtb) and I get a whole bunch of warnings. See below:
