AM625: 自己做的am6254板子 使用uart0下载tiboot3后无响应

Part Number: AM625


使用boot for uart 串口打印“”01000000011a0000616d36327800000000000000475020200100010001000100CCCCCCCCCCCCCCC"后用SecureCRT的xmodem传输官方镜像tiboot3完成后

Starting xmodem transfer.  Press Ctrl+C to cancel.
Transferring tiboot3.bin...
  100%     327 KB       7 KB/sec    00:00:45       0 Errors  

此处等待好几分钟后又出现如下:

01000000011a0000616d36327800000000000000475020200100010001000100CCCCCCCCCCCCCC

发现如果用sdk自己编译出来的tiboot3传输进入后直接死串口再没输出:

Starting xmodem transfer.  Press Ctrl+C to cancel.
Transferring tiboot3.bin...

现在一直下载不了tispl.bin 不知道是不是硬件哪里有问题!
