Raspberry pyQT KIOSK

i need to run a QT application on BOOT. and i want to disable all controls like minimize application, close application.
Anyone have experience in this? please help me.
THANKS! -
Hi @Akhil I found the following answer in one of the forums. here is the link to the thread.
The way that I've seen most people do it (have a look on the Raspberry Pi forums), and have done myself with success is using /etc/rc.local.
All you need to do here is put ./myscript in the rc.local text file. If it's in python, put python myscript.py.
This literally is "a simple solution, (like dropping my script in some "startup" directory or something similar)"- maybe search on the forums when you're having questions as well, this solution came up on the first 4 results of a google search!

I was trying to configure AP mode in Raspberrypi by using Network Manager. I'm using the below script. but it is throwing some errors.

Raspberry Pi Zero 2 W uses the same Broadcom BCM2710A1 SoC die as the launch version of Raspberry Pi 3, with Arm cores slightly down-clocked to 1GHz, bundled into a single space-saving package alongside 512MB of LPDDR2 SDRAM.
Here are the highlights:
Broadcom BCM2710A1, quad-core 64-bit SoC (Arm Cortex-A53 @ 1GHz) 512MB LPDDR2 SDRAM 2.4GHz IEEE 802.11b/g/n wireless LAN, * Bluetooth 4.2, BLE 1 × USB 2.0 interface with OTG HAT-compatible 40 pin I/O header footprint MicroSD card slot Mini HDMI port Composite video and reset pin solder points CSI-2 camera connector H.264, MPEG-4 decode (1080p30); H.264 encode (1080p30) OpenGL ES 1.1, 2.0 graphicssrc: https://www.raspberrypi.com/news/new-raspberry-pi-zero-2-w-2/

@salmanfaris Yeah, just like features and price, long term support is also crucial in determining the efficacy of a microcontroller. What RPi has done with the new introduction of the MCU is close to perfection. Like you said, they had everything ready before the release and that how it should be. No other manufacturer has ever done this before. RPi understands their users and what they seek, as always. With that, they have been able to pull something off that no other manufacturer could.
RP2040 is not just going to be used in hobby spectrum, but also high volume commercial applications. And that's why I said before it is setting off a REVOLUTION. It's just a matter of time RP2040 supersedes ATmega328 in popularity. Microchip has to worry again! 🤭
