Re: Shared lib symlinks in target image
Libraries have another symlink which looks something like libfoo.so.1 and 2 etc that is the one which should be used by apps On Mon, Oct 4, 2021 at 6:12 AM Lijun Chen <lijchen@...> wrote:

Re: Shared lib symlinks in target image
Lijun Chen
I have an app built in a different environment that has lower versioned libs, such as boost. I was wondering if on the target there are symlinks to those libs, whether the app can be run on a target that has newer libs without resbuild against a matched
env. Seems that is not viable. From: Khem Raj <raj.khem@...>

Re: Meta-raspberrypi - how to configure device tree for MCP251x
Chris Tapp
Sorry, I meant to add that I have tried adding the following to local.conf:
toggle quoted message
Show quoted text
RPI_EXTRA_CONFIG = ' \n \ dtparam=spi=on \n \ dtoverlay=mcp2515-can0,oscillator=16000000,interrupt=25 \n \ dtoverlay=mcp2515-can1,oscillator=16000000,interrupt=23 \n \ ' However, this did not make any difference to the interrupts. Since then, I have manually changed mcp2515-can1-overlay.dts in the kernel build tree (after running bitbake - c do_configure virtual/kernel) and rebuilt the kernel / image. This does result in the interrupt mapping changing, and both CAN channels then operate correctly. Does anyone know why RPI_EXTRA_CONFIG doesn’t appear to be taking effect? -- Chris Tapp ---- You can tell you're getting older when your car insurance gets real cheap!

Shared lib symlinks in target image
Lijun Chen
Hi,
When I build a yocto image, I added some packages into IMAGE_INSTALL, such as boost, thrift, etc. I notice in the target OS image, the shared libs don't the symlinks. But in the SDK image, the symlinks are there. For example, lrwxrwxrwx 1 root root 22 Oct 2 16:41 libboost_filesystem-mt.so -> libboost_filesystem.so
Is there a way to add the symlinks to the target image as well?
lrwxrwxrwx 1 root root 29 Oct 2 16:41 libboost_filesystem.so -> libboost_filesystem.so.1.75.0
With the symlinks, I assume we can run an old application even the dependent lib is a newer version?

How to include PostgreSQL development stuff in SDK?
tboeckel
Hi everybody!
I successfully built an image for an ARM based system running a PostgreSQL server and client by adding the packages "postgresql" and "postgresql-client". However, so far I failed to make the development stuff (libpq-fe.h, pg_config, etc) available in the generated
SDK.
Usuallly one uses pg_config to obtain the required include path (pg_config --includedir), the required compiler flags for C and C++ (pg_config --cflags and pg_config --cppflags) as well as the required linker flags (pg_config --libdir and pg_config --ldflags).
However, I get the warning during compilation of my own programs:
cc1plus: warning: include location "/usr/include/postgresql" is unsafe for cross-compilation [-Wpoison-system-directories]
Obviously the native pg_config binary of my Ubuntu system is called and hence causes references to the local installation of the libpq-dev package of my
Ubuntu system instead of a pg_config binary provided by the SDK. Even worse, the SDK just includes the pg_config binary for the ARM platform, but not for x86_64.
The only way to silence these warnings is to include -Wno-poison-system-directories in my compiler flags. But this is something I really like to avoid. Who
knows whether the PostgreSQL development stuff of my local Ubuntu system will always be compatible to the one for the ARM system?
Unfortunately I had no luck including the PostgreSQL development stuff in the SDK. I already tried 'TOOLCHAIN_HOST_TASK_append
= " nativesdk-postgresql"', but this ends in an error message like this:
ERROR: Nothing RPROVIDES 'nativesdk-postgresql' (but /opt/PHYTEC_BSPs/yocto_imx7/sources/poky/meta/recipes-core/meta/buildtools-tarball.bb, /opt/PHYTEC_BSPs/yocto_imx7/sources/poky/meta/recipes-core/meta/uninative-tarball.bb
RDEPENDS on or otherwise requires it)
NOTE: Runtime target 'nativesdk-postgresql' is unbuildable, removing...
Missing or unbuildable dependency chain was: ['nativesdk-postgresql']
ERROR: Required build target 'fsl-image-qt5' has no buildable providers.
Missing or unbuildable dependency chain was: ['fsl-image-qt5', 'buildtools-tarball', 'nativesdk-postgresql']
Adding 'PACKAGECONFIG_append_pn-nativesdk += " postgresql"' also does not cause the x86_64 binary of pg_config to be included in the SDK. I assume
this causes the ARM binary to be included, but this cannot be used on an x86_64 system.
I searched lots of sites for a solution already, but so far I only found hints how to add packages in general, but nothing in respect to this specific issue.
Can anybody please point out what I am doing wrong or what I need to change to solve this issue?
Many thanks in advance!

Meta-raspberrypi - how to configure device tree for MCP251x
Chris Tapp
I am having trouble getting the Waveshare 2-CH CAN HAT working with an RPI4. Channel 0 does not come up, channel 1 does, but it will only send one message (eventually reporting "write: No buffer space available”) and not receive anything.
Looking at the mcp2515-can0-overlay.dts and mcp2515-can1-overlay.dts device tree files in /tmp/work-shared/raspberrypi4/kernel-source/arch/arm/boot/dts/overlays/, it looks as if the interrupts are not mapped as required for the board. DTS HAT CAN0 brcm,pins = <25> PIN23 CAN1 brcm,pins = <25> PIN25 This doesn’t look right, and seems consistent with the behaviour I am seeing. I would also like to check the device chip select signals, but I can't see how (if) they are mapped in the dts files. How can I override these settings when I build the image? |

[meta-rockchip][PATCH] rockchip.wks: use uuid for /boot during fstab-update
Markus Volk
Since the recent patch to switch to UUIDs [0aa5e600: "use uuid
instead of hard-coding root device"] wic fstab-update is not able to get the correct value for the used device anymore and falls to the default 'sda'. Thus wrong /dev/sda entries are generated in fstab. For partitions that should be updated automatically this can be avoided by either generate entries using uuid or label.

How to enable and disable device tree node at runtime from linux userspace
#dunfell
james@...
Hai All,
I wanted to use a GPIO to put the SOM into sleep mode and again use it to wake it up from the sleep. I used the below node to configure the SOM to use the GPIO1 18 to wake up from sleep. keys {
compatible = "gpio-keys";
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_gpio_userkeys> ;
wakeup {
gpios = <&gpio1 18 GPIO_ACTIVE_LOW>;
linux,code = <KEY_WAKEUP>;
gpio-key,wakeup;
};
} But again to put into sleep I am unable to read the GPIO state from linux userspace as it is used by driver. I am using libgpiod to read the gpio status for which I am getting device or resource busy error # gpioget gpiochip0 18
gpioget: error reading GPIO values: Device or resource busy
How to disable the device tree node from linux user space so it is possible to read the GPIO staus. And onces the button is pressed enable the device tree node and enter the sleep mode so the driver will take care of waking of the SOM. Or Any other way to force read the status of GPIO status Regards, James A |
