    The steps to re-create SD card are as follows:
    1：Direct use of the file on IPNC RDK 3.9.1, with the following command:
    sudo./mksd-ti81xx.sh/dev/sdb/home/zhangchun/ti/ipnc_rdk-3.9.1/Source/ipnc_rdk/binaries/DM388/sd/MLO/home/zhangchun/ti/ipnc_rdk-3.9.1/Source/ipnc_rdk/binaries/DM388/sd/u-boot.img/home/zhangchun/ti/ipnc_rdk-3.9.1/Source/ipnc_rdk/binaries/DM388/sd/dm38x-csk.dtb/home/zhangchun/ti/ipnc_rdk-3.9.1/Source/ipnc_rdk/binaries/DM388/sd/uImage/home/zhangchun/ti/ipnc_rdk-3.9.1/Source/ipnc_rdk/binaries/DM388/sd/filesystem_DM388_FULL_FEATURE.tar.gz

    The information of the terminal is as follows:
    zhangchun@zhangchun-LIFEBOOK-LH532:~/ti/ipnc_rdk-3.9.1/Utils/sd-script$ sudo ./mksd-ti81xx.sh /dev/sdb /home/zhangchun/ti/ipnc_rdk-3.9.1/Source/ipnc_rdk/binaries/DM388/sd/MLO /home/zhangchun/ti/ipnc_rdk-3.9.1/Source/ipnc_rdk/binaries/DM388/sd/u-boot.img /home/zhangchun/ti/ipnc_rdk-3.9.1/Source/ipnc_rdk/binaries/DM388/sd/dm38x-csk.dtb /home/zhangchun/ti/ipnc_rdk-3.9.1/Source/ipnc_rdk/binaries/DM388/sd/uImage /home/zhangchun/ti/ipnc_rdk-3.9.1/Source/ipnc_rdk/binaries/DM388/sd/filesystem_DM388_FULL_FEATURE.tar.gz

    The switch is set to sd card boot. I suspect DDR is a problem. How to determine whether DDR works properly?

    We purchased the TMDSCSK388-CSKCC-BNDL in ti-store on December 16,2017. order no: 1682548. Can't work all the time.

    Contacted ti-china, they said that it was necessary for e2e's engineers to decide what was the problem?

    Hope e2e's engineer will reply as soon as possible.

    Thanks & Regards,
