Data transfer from GPIO port to RAM buffer using DMA upon receiving a trigger signal on the timer capture input channel. Our requirement is to configure the DMA so that it transfers data from the GPIO lines (8 bit data lines) to the RAM buffer upon r
I got the following error message when trying to open a network interface for capture using Wireshark on Mac OS X (Wireshark 1.5.1 Intel 64 beta and 1.4.6 Intel 64 show this behaviour): There are no interfaces on which a capture can be done. To solve
Linux内核suspend状态 Linux内核支持多种类型的睡眠状态,通过设置不同的模块进入低功耗模式来达到省电功能.目前存在四种模式:suspend to idle.power-on standby(Standby).suspend to ram(STR)和sudpend to disk(Hibernate),分别对应ACPI状态的S0.S1.S3和S4. Suspend to idle完全是软件相关的并且尽量将CPU维持在深度idle状态. Power-on standby设置设备进入低功
Wireshark设置interface 时提示“There are no interfaces on which a capture can be done ” 解决方法: 今天在电脑上安装了WIRESHARK软件,在设置interface 时提示"There are no interfaces on which a capture can be done" 提示没有任何一个网络接口准备好.此提示明显是不对的, 我的网卡明明可以正常上网,网络接口怎么会没有准备好呢? 想着应该是和

汇编代码主要是初始化一些寄存器,关狗,初始化时钟,初始化存储管理器以便访问内存,然后将SoC上4k RAM数据拷贝至SDRAM,然后在SRAM里面运行,由于代码未正常跑起来,于是使用JLinkExe来调试.JLinkExe指定了一个命令文件: JLinkExe -commandfile ./cmd.jlink ,cmd.jlink文件内容如下: r loadbin /home/thomas/learn/armasm/addresses/main.bin 0x0 setbp 0x0 a s set
