I am working on a Qualcomm-based embedded Linux platform using a platform driver for a peripheral (UART/I2C/WiFi). The driver uses a device tree match table and implements a probe() and remove(). The ...

Introduction: I'm using a custom board based on an i.MX6q SoC that communicates with an FPGA on the EIM bus: this communication is managed via custom driver module. The DTACK signal and memory WDOG ...

I using u-boot v2017.09 for rk3566, i want to load kernel from FIT(kernel, dtb, ramdisk). I hardcoded bootargs(boot_get_cmdline) in u-boot: int boot_get_cmdline(struct lmb *lmb, ulong *cmd_start, ...

How can I enable XNNPACK on a Raspberry Pi 5 for an INT8 TensorFlow Lite model? I have a quantized INT8 TensorFlow Lite model that I want to run efficiently on my Raspberry Pi 5. I’ve read that ...

I have a single board computer with a I2C GPIO expander device, listed as /dev/i2c-0. In my multithreaded program I open() this character device and read/write to it on separate threads using ...

I have been working on multiple projects of Embedded Linux from last 5 years but there is a small problem when I use UART. I am using STM32MP13F with MYIR board. The UART is connected to half duplex ...

I'm trying to create a Bitbake recipe which imports the Clickhouse python library. I'm following the example set in this post. I have a unique problem in that the name of the recipe is very sensitive ...

I have a device driver that provides quite simple functionality that does not belong to any of the classes. The driver exposes one attribute through sysfs. Currently I can get an access to my device ...

I am trying to build a driver for my IP in an FPGA. I have: static const struct of_device_id myip_of_match[] = { { .compatible = "xlnx,myip-controller-1.022", }, {}, }; ...

Each scheduling policy (like SCHED_NORMAL, SCHED_FIFO etc..) is implemented as a struct sched_class, and instances like fair_sched_class, rt_sched_class, dl_sched_class, etc., are defined using the ...

I'm building a kernel image, with my own kernel module being added to the build, using my own Makefile and Kbuild scripts. The final complete kernel image gets flashed to a ROM. I have a few kernel ...

I'm developing a Linux kernel driver for the BeagleBone Black and want to use two GPIOs available on the P9 expansion header: P9.15 → gpio1_16 → connected to an LED P9.23 → gpio1_17 → connected to a ...

When testing linux kernel 5.10 on Zynq-7010 FPGA with multiple sequential interrupts I get Unhandled fault: imprecise external abort (0x1406) from the interrupt handler an example of the failure (from ...

If I'm working for example with the Xilinx ZU2CG SoC, and a pin named as an "AC3" (xczu2cgsfvc784 pinout) is interesting for me, where can I find what is the gpio number under Linux for that ...

I have built 6.6.x linux kernel : https://github.com/raspberrypi/linux/tree/rpi-6.6.y for RPi3B+ (arm64 target). The rootfs came from buildroot-2025.05-arm64. I am running it on RPi3B+ and following ...
