等)都是对DDR2/mDDR Controller 这部分一个总的概述,只讲了DDR2/mDDR Controller 寄存器的地址,功能等,没有精确到每个寄存器每一位的详细配置。我想找到DDR2

1.板子是logicPD的evmOMAPL138,我现在想让应用能够从SPI0 Flash加载到mDDR中运行。如果用AISgen工具来设置,应该要怎么配置?有没有参考的配置文件? 2.如果是想在程序中初始化mDDR,应该要怎么设置??

spiflash搬运 uboot到内存mddr中时,会漏掉开头的一些uboot的相关信息,如uboot的起始地址等,但rbl是能从flash搬运ubl的,这时怎回事啊,有没有可能在烧写时的握手出了问题?对spiwriter.out有些疑问,这个烧写程序是怎样实现和spiflash握手烧写的?

本帖最后由 一只耳朵怪 于 2018-6-6 16:22 编辑 在UBL中有mDDR的具体设置而在uboot中的cpu/arm926ejs/davinci的lowlevel_init.S中也有

所有段都放在SHRAM,CPU不连接DDR2,程序能否正常运行?3、开发板的DDR2是连接在DDR2/mDDR Memory Controller上的吗?初学者小白一个,可能问题比较弱智……

我使用sfh_OMAP-L138.exe串口烧写工具来烧写UBL、UBOOT时,在擦除的过程中总是停止在Waiting for SFT on the OMAP-L138...这,具体信息如下: C:\temp>sfh_OMAP-L138.exe -erase -targetType OMAPL138 -flashType NAND -P COM4 ----------------------------------------------------- TI Serial Flasher Host Program for OMAP-L138 (C) 2010, Texas Instruments, Inc.
