Describe the bug In some cases the write semaphore is used before it was initialized. This leads to a fatal error. In my case this happens just after irq_enable(USB_IRQ); (https://github.com/zephyrproject-rtos/zephyr/blob/main/drivers/usb/device/usb_dc_rpi_pico.c#L1076) To Reproduce ...
Raspberry Pi的Linux内核，在架构上与标准的Linux内核高度相似，主要包含以下几个核心组件：内核核心（Kernel Core）：负责系统启动、进程调度、内存分配、中断处理等核心功能。文件系统（Filesystem）：管理文件和目录，为数据存储和访问提供接口。设备驱动（Device Drivers）：为各种硬件设备提供驱动程序，使它们能够与内核...
Raspberry Pi 3B Kernel 配置 使用Buildroot为Raspberry Pi 3B编译Linux kernel ,使用的是默认的raspberrypi3_64_defconfig配置。 在Buildroot根目录下,运行:make raspberrypi3_64_defconfig。 同时还要使用make linux-menuconfig命令配置Alsa驱动:Device Drivers ---> Sound card support ---> Advanced Linux Sound Achit...
1、下载树莓派Linux的内核源码 源码地址:https://github.com/raspberrypi/linux 选择所需编译的分支版本:4.14.y # git clone --depth=1 -b rpi-4.14.yhttps://github.com/raspberrypi/linux.git 众所周知,国内直接下载github的源码是比较慢的,所以在此提供一个高速下载的地址 # git clone --depth=1-b rp...

Device Drivers > PTP clock support > OpenCompute TimeCard as PTP clock To use the Pi as a PTP hardware timestamping grandmaster clock, you need to have a NIC with hardware timestamping support.The NIC built into the CM4 (Broadcom BCM54210PE PHY) has PTP support, but the IEEE1588-2008...
eventually reach that goal.OnRaspberryPi,DeviceTreeusageiscontrolled from/boot/config.txt.Bydefault,theRaspberryPikernel boots with device tree enabled.Youcan completely disableDTusage(fornow)by adding:device_tree=to your config.txt,which should cause yourPito revert to the old way of ...
With the release of the Raspberry Pi 2 we have seen Raspbian receive the speed boost that it always needed, by no means was it a slouch on the original Raspberry Pi, but the addition of more RAM and better CPU has enabled it to become a usable desktop distro that can easily be used ...
Device Drivers -> Network device support -> Ethernet driver support -> Mellanox Devices -> Mellanox Technologies 1/10/40Gbit Ethernet support Three are also Mellanox OFED drivers, but they have been tricky to install. The link LED gets lit, the interface is seen by the Raspberry Pi, but ...
