TMS320DM6446的UBL和UBOOT串口烧写问题

各位专家们，好。我这边现有个关于TMS320DM6446烧写UBOOT问题希望得到你们的支持。问题是这样的，我通过命令“sfh_DM644x.exe  -flash  UBL_DM6446_NAND.bin  u-boot-1.2.0_DM6446_NAND.bin”烧写UBOOT，在烧写过程中出错如下错误：

Sending the UBL image

Waiting for SENDIMG sequence...

UART response didnt match

Command failed, retrying

上述提示信息一直重复输出。

请问什么原因可能会造成上述提示信息？

    您好，烧写NAND的时候，要注意先擦后写，

    命令要准确：

    Flash the NAND attached to DM6446 with a UBL and u-boot image

      sfh_DM644x.exe -flash -flashType NAND -targetType DM6446 <UBL binary file> <u-boot binary file>
