sram_060803
- SRAM的读写代码,对SRAM进行了乒乓操作,用VHDL语言进行设计,很有参考价值,甚至可以直接复制代码来进行自己的设计-SRAM read and write code, ping-pong operation carried out on the SRAM, using VHDL language design, of great reference value, or even directly copy the code to carry out their own designs
LPC2220_BOOTLOAD_UART_
- MCU为LPC2220,FLASH为39FV1601(地址0x80000000),外部一个SRAM(地址0x81000000),程序用ADS编译, 用分散加载,程序0x80000000开始引导,FLASH操作在LPC2220内部RAM运行。 实现的作用为开机等待2秒左右若PC发来连接指令将进入BOOT部分,若超时则COPY应用程序到外部RAM开始运行。 抛砖引玉,可以认识到分散加载,BOOT的基本原理及方法,该程序已可完成所有功能,但可能仍然需要补足一些 如FLASH坏区检查等,

U-Boot启动第二阶段代码分析
- U-Boot第一阶段的启动流程。(nandflash启动,把nand的4k代码考到sram中,因为nand没址线,不能映射到内存,所以通过sram进行过度,sram中4k代码把整个uboot拷贝到sdram上,初始化好堆栈,为c语言提供条件,进入uboot的第二阶段! )这个阶段主要是初始化硬件设备,为加载U-Boot的第二阶段代码准备RAM空间最后跳转到lib_arm/board.c中start_armboot函数,这是第二阶段的入口点。(U-Boot first phase of the s
DSP_run_flash&sram
- 本文介绍了两种烧写模式,一种是烧写进flash,一种是烧写进sram,在两个文件夹内,并且每种模式已经整理好源代码,分享给大家。(This article introduces two burning mode, one is burning into flash, the other is burning into sram, in two folders, and each mode has been sorted out the source code, to share with you
