TMS320DM8148: DVRRDK_04.01.00.02

user6600074

Part Number: TMS320DM8148

   我使用DVRRDK_04.01.00.02 开发包，芯片是TMS320DM8148。

   板子上配的DDR是2G，

   目前uboot已经能识别了

    

 

现在的问题是2G的 config_2G.bld内存分配文件不对，系统起不来，

DVRRDK_04.01.00.02 开发包只有512M的内存分配文件，

我参考网上以及8168的1g的配置文件，8148的1g内存分配也ok了

但是2g的内存分配文件，系统一直起不来。

   这个是我目前用的配置文件。

     一直这个bug：BUG: Your driver calls ioremap() on system memory. This leads
                                       to architecturally unpredictable behaviour on ARMv6+, and ioremap()
                                       will fail in the next kernel release. Please fix your driver.

    我试了好多，一直解决不了，有哪位大神能解决这个问题，可以支付报酬。

    不行，用这这里的config_2G.bld 编译不通过。

    没有有知道吗。是不是没有人这么使用过，官方的人员提的建议也没什么用啊。

    我下载了http://e2e.ti.com/cfs-file.ashx/__key/communityserver-discussions-components-files/716/5621.ti814x.rar中的文件，编译不通过，改了一些size的大小，能编译通过，但是烧写后，系统还是起不来。

    这个是我设置的bootargs

    bootargs=console=ttyO0,115200n8 noinitrd mem=512M rootwait=3 rw ubi.mtd=5,2048 rootfstype=ubifs root=ubi0:rootfs init=/init dhcp notifyk.vpssm3_sva=0xBFB00000 earlyprintk ddr_mem=2048M vram=64M vmalloc=476M

    这个是我目前用的配置文件。

    还是包这个bug：BUG: Your driver calls ioremap() on system memory. This leads
    to architecturally unpredictable behaviour on ARMv6+, and ioremap()
    will fail in the next kernel release. Please fix your driver.

    我Rules.make 中的设置 ：DVR_RDK_BOARD_TYPE := DM814X_BCH_DVR

    ifeq ($(PLATFORM), ti814x-evm)
    ifeq ($(DDR_MEM), )
    # DDR_MEM := DDR_MEM_512M
    # DDR_MEM := DDR_MEM_1024M
    DDR_MEM := DDR_MEM_2048M
    endif
    ifeq ($(LINUX_MEM),)
    # LINUX_MEM := LINUX_MEM_128M
    # LINUX_MEM := LINUX_MEM_256M
    LINUX_MEM := LINUX_MEM_512M
    endif
