I am rather new to eclipse hawkbit and SWupdate I have been trying to do a test implementation on a RPi before I go with the production implementation.
I have Hawkbit up and running but I am having several problems with SWupdate, I have built a core-image-full-cmdline.wic and the .swu update Image along with it:
This is the local.conf:
MACHINE = "raspberrypi3"
IMAGE_FSTYPES += "wic"
RPI_USE_U_BOOT = "1"
KERNEL_IMAGETYPE = "uImage"
IMAGE_INSTALL_append = " kernel-image kernel-modules"
#WKS_FILES_raspberrypi3 = "ts-raspberrypi.wks"
PREFERRED_PROVIDER_u-boot-fw-utils = "libubootenv"
DISTRO_FEATURES_append = " systemd"
DISTRO_FEATURES_BACKFILL_CONSIDERED += "sysvinit"
VIRTUAL-RUNTIME_init_manager = "systemd"
VIRTUAL-RUNTIME_initscripts = "systemd-compat-units"
ENABLE_UART = "1"
I also got this error when I changed the IMAGE_FSTYPE from ext4 rpimg to wic:
ERROR: update-image-1.0-r0 do_swuimage: swupdate cannot find image file: /home/aswin/yocto/build/tmp/deploy/images/raspberrypi3/core-image-full-cmdline.ext4.gz
ERROR: Logfile of failure stored in: /home/aswin/yocto/build/tmp/work/raspberrypi3-poky-linux-gnueabi/update-image/1.0-r0/temp/log.do_swuimage.87006
ERROR: Task (/home/aswin/yocto/layers/meta-swupdate-boards/recipes-extended/images/update-image.bb:do_swuimage) failed with exit code '1'
So I had to change the update-image.bb FSTYPE = ".wic"
And when I comment this out #WKS_FILES_raspberrypi3 = "ts-raspberrypi.wks"
Then flash the image to a sd card and boot it nothing really shows up except for a blinking line. If I leave it, then the .swu file is way too big to upload it to hawkbit.
How do you expect it to work when you have HW compatibility errors, JSON file corrupted errors, forget about the hawkbit for now, and try to see if your sw-description file is creating the correct swu image file that updates the rootsfs or whatever you want to update using mongoose webserver and only then move on to the hawkbit.
First solve the errors that are coming before
suitable .swu image not found
Edited: please also put the sw-descirption file that you are using to create your swu file for further help.

I'm trying to use the ocaml-mm package (https://github.com/savonet/ocaml-mm) and trying to run one of the examples for sine_wav.ml
I first installed the package and also installed the ao library, which the sine_wav file uses. Everything compiles, but I get this error when I'm trying to run the file:
ddavidjeong#DESKTOP-60PESIS:~/cs3110/ms/test$ make main
Entering directory '/home/ddavidjeong/cs3110/ms'
Fatal error: exception Failure("Failed to open device")
make: *** [Makefile:2: main] Error 2
ddavidjeong#DESKTOP-60PESIS:~/cs3110/ms/test$
I have no idea what this exception could refer to.
This errors means that the libao library failed to open its default audio device. You can at least check which default device was found by the library by using in utop
#require "ao";;
Ao.get_default_driver ()
```ocaml
Similarly, you can get the list of all audio device found by libao with
```ocaml
Ao.drivers;;
If there is no visible issue with the default driver, and there is some non-default driver available that looks like they might work; it would be possible to try to use another device in sin_wave.ml by replacing the instance of the Mm_ao.writer class in
let ao = new Mm_ao.writer channels sample_rate in
by an instance of
class ao_writer driver channels rate = object
object
val dev = Ao.open_live ~driver ~channels ~rate ~byte_format:`LITTLE_ENDIAN ()
method write buf ofs len =
let s = Audio.S16LE.make buf ofs len in
Ao.play dev s
method close = Ao.close dev
end
with the right driver.
But it is probably better to see why libao cannot open the default device that it selected itself.
I want to build a PetaLinux Image for my Ultra96v2.
I followed this guide up until building my application project in Vitis. It looks promising but then while building the application project for my custom platform, Vitis throws this error:

It specifically shows me, that there is a comma in the path where it searches for the file. The files are available
at the "normal" location, without the "atf,", "dtb,", etc
at the "weird" location. I created the path so the requested path exists for every file that throws an error message, like
/media/user/6b04b610-ff80-4702-a575-b0b1a78fbafb/dpu_pkg/dpu_appl_system/Debug/sd_card_temp/boot.bif". ... emo/sw/atf,dpu_demo/boot/bl31.elf
I created the path with the weird artefact "arf,dpu_demo", with the komma in the path, but still it wont work. Is this some kind of problem with Vitis, like some env variables not set correctly, or is the building mechanism just acting weird? I cant resolve this issue, because I am not able to change the paths it is supposed to look for the files. This hinders me in advancing my project. I work on Ubuntu 20.04.
Can anyone help me out here, please? I would really appreciate it!
I asked this question in the Xilinx Community, too, but unfortunately there was no resonance at all.
Thank you so much in advance!
PLEASE READ THE WHOLE ANSWER FOR ACTUAL SOLUTION
I think I got it now, though I did not verify whether the image actually works on my Ultra96v2, yet.
I noticed, that the weird path with commata is inside of the boot.bif and system.bif.
So the first time I tried to build it, the bif wasnt there, but got created (I assume). The bif was ready then but only had a weird path inside, so I took the makefile (you can find it in debug/sd_card), copied it, and just commented out the line GENERATE_BIF_XSCT_CMD = ${GENERATE_BIF} -xpfm ${XPFM_PATH} -domains ${DOMAINS} -bifpath ${BIF_PATH}.
Then I edited the boot.bif and system.bif and changed the atf,boot, uboot,boot, and dts,boot to just boot, so the BootGen wouldnt look into the directories with the commata anymore, but only the boot-directory which was specified.
Once that was set up, I executed the edited makefile in my console, by going into the sd_card-directory and executing the following command:
make -f <your_edited_makefile>
This means, that you cant press "build" in Vitis, it wont work. You build the content on your own and wont get a green check mark beside the project! Then the sd_card-directory was populated with (I assume) all necessary data to boot the Ultra96v2 from SD card. This was the content:
boot.scr
BOOT.BIN
dpu_appl.elf (your application project name, I guess)
README.txt
system.dtb
The underlying issue seem to have been that the ::scw::generate_bif created a path to look after, which didnt exist. Really weird issue, in my opinion.
UPDATE:
I just made some changes to the PetaLinux config with the petalinux-config command and rebuilt everything. Once I go to the Vitis part, I changed the system.bif within Vitis itself, and the project compiled successfully, also populating the sd_card directory, as it seems.
UPDATE 2:
Everything failed, so I tried to get to the *.bif of the Application System project. I opened it (linux.bif) and edited the "atf,", "dtb," and "uboot," out of it. Since this is only created once and references by the following files, this fixed my issue and the build was completed successfully in Vitis. So just ignore my originial answer and update.
I hope this is working and hope it will help some of you.
I'm currently trying to set up an environment for Yocto project for my personal study.
I was clueless about where to start Yocto so I bought the book Embedded Linux Projects Using Yocto Project Cookbook but it keeps failing to build the environment.
I've run only simple commands. I ran source oe-init-build-env <dir name> to make a directory and ran bitbake core-image-minimal.
But bitbake command keeps giving me errors like this. This is the log.

I feel like I need to modify conf files to fetch available URLs but I'm new to Yocto and Bitbake so I'm very lost now. I would appreciate if anyone could tell me where to find solutions. Thank you and stay safe everyone.
You seem to use quite an old yocto version 1.7.3 while there is already 3.3 released. This means also you try to build recipes for some packages that are also old and hence some URLs might be unavailable. Might it be an option for you to use a newer version?
If this is no option for you, one thing to try would be setting MIRROR (see [1]) to a mirror [2] where those packages are still available. But this approach I would not prefer.
[1] https://www.yoctoproject.org/docs/1.7/bitbake-user-manual/bitbake-user-manual.html#var-MIRRORS
[2] could be: http://downloads.yoctoproject.org/mirror/sources/
1.7.3 is a very old release of the project, originally released in 2015 with a last point release in 2016. The fetcher warnings you see aren't the problem, they're warnings but it will fall back to the project mirrors. If it hadn't fallen back correctly, it would have shown errors as well as the warnings. The bigger problem is in fact this:
WARNING: Host distribution "Ubuntu-18.04" has not been validated with this version of the build system; you may possibly experience unexpected failures. It is recommended that you use a tested distribution.
Since Ubuntu 18.04 is three years newer than the project release you're using, there is no way it would be compatible with that release. You need to use a host OS from the era of the release, so Ubuntu 16.04 may work better. This is because the host OS provides gcc used to build the cross tools and the newer gcc versions don't tend to work with 100% of old code without tweaks.
So in short, use an older distro if you want to try and get that to build.
I am developing on a Qt project, and have installed Qt from their installer onto my computer. In Visual Studio it is simple to debug-step into Qt sources: when I enter a function in an unknown file, it will open a file browser to let me locate the original Qt source code.
Is there an equivalent function in Xcode or LLDB?
The debug information records the location of the QT source files when they were built. You can find this information by doing:
(lldb) image lookup -va main
Address: hello[0x0000000100000f40] (hello.__TEXT.__text + 0)
Summary: hello`main at hello.c:5
Module: file = "/private/tmp/hello", arch = "x86_64"
CompileUnit: id = {0x00000000}, file = "/tmp/hello.c", language = "ISO C:1999"
Function: id = {0x00000026}, name = "main", range = [0x0000000100000f40-0x0000000100000f6d)
FuncType: id = {0x00000026}, decl = hello.c:4, clang_type = "int (void)"
Blocks: id = {0x00000026}, range = [0x100000f40-0x100000f6d)
LineEntry: [0x0000000100000f40-0x0000000100000f56): /tmp/hello.c:5
Symbol: id = {0x00000004}, range = [0x0000000100000f40-0x0000000100000f6d), name="main"
but substitute some QT function for "main". Then look at the CompileUnit line and see what the "file" entry says. Suppose it says
"/BuildDirectory/sources/SomeSubdirectory/SomeFile.cpp"
Now presumably you've downloaded the QT sources, and they live somewhere on your local machine, say in
"/Users/ME/QT/sources"
So what you want to do is tell lldb: "when you see a source file rooted at /BuildDirectory/sources, look in /Users/ME/QT/sources instead." You do that with the lldb "target.source-map" setting. In this example, you would say:
(lldb) settings set target.source-map /BuildDirectory/sources /Users/ME/QT/sources
You can type that in on the command line or put it in your .lldbinit file for more general use. lldb will update its source maps automatically, but if you are running in Xcode, you'll have to step once after issuing the command to get it to update.

cURL is most likely not installed correctly or linked up to PHP. Windows does not come with cURL installed (another reason to switch to a *nix based system! but I digress) so you'll need the appropriate dll files to enable it, then link those in via your php.ini file.
