dsp c5517--On-ChipSingle-AccessRead-OnlyMemory 128kb 里面有什么东西?

Expert 2137 points


老师您好:我在自己写 cmd的文件,我想具体了解下 c5517--On-ChipSingle-AccessRead-OnlyMemory 128kb 具体有哪些东西?

我看到官方的cmd文件只用到PDROM   (RIX): origin = 0xff8000, length = 0x008000  /*  32KB */

为什么不是PDROM   (RIX): origin = 0xfe0000, length = 0x020000  /*  128KB */

  • PDROM里是芯片出厂前固化了bootloader代码,内容见boot文档。

    cmd文件不用定义PDROM,因为ROM是只读的,不能存放数据代码在这块地址。
