AM3354: am3354 移植sdk-evm-07.03, 内核卡在Unhandled fault: external abort on non-linefetch (0x1008) at 0xd02e6000

Part Number: AM3354
Other Parts Discussed in Thread: TPS65910, , AM3352

TI fae及各位大侠好:

当前使用am3354平台,搭配镁光ddr3 SCB13H2G160AF(256MB),镁光nand flash MX30LF4G18AC MT29F4G08ABADA (512MB),PMIC为tps65910

编译sdk07.03.00,其u-boot为2020.01, linux内核为5.4.106

编译好u-boot 2020.01通过串口更新下载,然后搭建tftp加载引导内核dtb和image,系统启动后,卡在Unhandled fault: external abort on non-linefetch (0x1008) at 0xd02e6000,具体日志如下:

linux内核5.4.106选用config和dts分别为:tisdk_am335x-evm_defconfig和am335x-evm.dts

编译内核的步骤如下:

$ cd source_code/ti-processor-sdk-linux-am335x-evm-07.03.00.005/board-support/linux-5.4.106+gitAUTOINC+023faefa70-g023faefa70
$ source ./environment-setup
$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- distclean
$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- tisdk_am335x-evm_defconfig
$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- am335x-evm.dtb                              //支持nand flash
$ make ARCH=arm CROSS_COMPILE=arm-none-linux-gnueabihf- LOADADDR=0x80008000 uImage

tftp网络加载内核dtb和uImage如下:

set bootargs noinitrd root=/dev/nfs rw nfsroot=192.168.7.170:/home/d/wangyuan/imac120/ti-processor-sdk-linux-am335x-evm-07.03.00.005/targetNFS ip=192.168.7.235:::::eth0:off console=ttyO0,115200n8 loglevel=8
setenv ipaddr 192.168.7.235
setenv gatewayip 192.168.7.1
setenv serverip 192.168.7.47
setenv netmask 255.255.255.0
tftp 0x82000000 uImage                   //参考u-boot环境变量(pri)进行设置
tftp 0x88000000 am335x-evm.dtb    //参考u-boot环境变量(pri)进行设置
bootm 0x82000000 - 0x88000000

目前通过错误提示,也定位不到原因,帮忙具体看下:

通过arm-none-linux-gnueabihf-addr2line分析定位问题,具体出错如下:

以上显示,汇编代码处理出错,属于io处理
