Qt for MCUs

@Vishal-Biradar said in Code is getting reset.: But after certain period code is resting means display is getting off again restart Do you mean your app is crashing? The OS is restarting? Please say exactly what happens. Regarding your code: using an endless loop in an event driven application is a no-go...

Hi again, This is a follow-up to my earlier post regarding the Spark font engine integration with complexTextRendering enabled. I’ve resolved all the build-time errors related to Spark integration, and both the platform and application layers build successfully. However, after flashing the final binary onto the hardware, all the text has disappeared from the screen — only images are visible. It seems like text rendering is completely missing at runtime. Regarding the previous suggestion to use the ldd tool to check for library dependencies — thank you for the recommendation. Since I'm working on different OS and building with MinGW, I wasn’t able to use ldd directly but did try some alternative tools available for Windows that perform similar dependency checks. Has anyone experienced a similar issue where the text doesn't appear on hardware after enabling Spark font engine with complexTextRendering = true? Any insights on what could be going wrong or how to debug this would be greatly appreciated. Thanks in advance!

@remo999 Please keep in mind: this is user forum. If you do not get an answer here you can contact Qt developers on their mailing list.

Hi and welcome to devnet, Boot2Qt being a commercial offer, you will likely have better chance of an answer by contacting the Qt Company directlyy

@Vishal-Biradar I don't know what tool is not found and why. Seems to be "Renesas Flash Programmer", but I don't know why it is not found. Maybe it needs to be installed and added to PATH?

@jsulm Thank you for your response I thought of that but was not sure if it was the way to go , but since the Qt kit for the board is bare metal i dont see any other way

@britesc I know nothing about this :) But did some Googling which may help? First I will say I was "surprised" that your work and the instructions seems to fetch/use "Qt5" stuff when you want to build Qt6, but I guess that's right, for whatever reason! For your error message I came across https://github.com/microsoft/vcpkg/issues/32135#issuecomment-1603081312 I was able to resolve this issue by installing the additional required packages for qt5base (although I am targeting q6) and X11 required by qt5-base for qt5-x11extras APT_PACKAGES="$APT_PACKAGES libxkbcommon-dev libxcb-keysyms1-dev \ libxcb-image0-dev libxcb-shm0-dev libxcb-icccm4-dev libxcb-sync-dev \ libxcb-xfixes0-dev libxcb-shape0-dev libxcb-randr0-dev \ libxcb-render-util0-dev libxcb-xinerama0-dev libxcb-xkb-dev libxcb-xinput-dev" Does this list of dependencies have any relevance for your situation? That's all I know! P.S. I see @jsulm has just posted. You should listen to him more than to me!

@IBO_GO in which language did you write your HAL ? Because if it's either C or C++ you can use that as any other library. If not, then please give more details about what you already have, in which language, etc.

Never mind guys @JonB @SGaist i figured it out, thanks for the response.

@jsulm said in Using LIRC in Qt creator: @markolino_it said in Using LIRC in Qt creator: I don't know if in my old version of qt5 there is the package manager. @SGaist was talking about the packet manager of your Linux distribution! Sinse Raspbian is a Debian derivate you have to use apt. All you have to do is: sudo apt install liblirc-dev Oh sorry, now I understand. Yes i use it a lot of course...for the other packages, sorry for that I am a noob of Linux! So I will test the Lirc-less solution and Lirc solution and I let you know. Thank you.
