TI中文支持网问题：
我使用sfh_OMAP-L138.exe串口烧写工具来烧写UBL、UBOOT时，在擦除的过程中总是停止在Waiting for SFT on the OMAP-L138…这，具体信息如下：
C:\temp>sfh_OMAP-L138 -erase -targetType AM1808 -flashType SPI_MEM -v -p Com8

说明：
uboot 和linux的默认调试口为 UART2 ，之前我用 UART2作为调试口的时候一切都很顺利，现在因为硬件的影响 想用 UART0 作为调试口，就出现了上述的问题 Waiting for SFT on the OMAP-L138…
希望可以给点思路

如果用自己的开发板, 需要做一些修改, 可以参考下面的wiki网站.

noaming：
你好，该换串口，注意：OMAP-L138/Common/include/device_uart.h: Modify the #define DEVICE_UART_PERIPHNUM to set which UART is connected to the host PC.
