F28069调试单步运行可以，全速运行跑飞

    while(1)
	{
		count_n++;
//    	DELAY_US(10000);

		BSP_LED_Toggle(LED1);

	}

主程序的大循环只有闪灯的代码，单步运行灯可以闪，全速运行程序跑飞，调用delay会进入illegal_isr。

自己设计的板子，请问一下这是什么情况？

    对f28069_xds100v2.ccxml文件执行test connection，发现有错误：

    [Start: Texas Instruments XDS100v2 USB Emulator_0]

    Execute the command:

    %ccs_base%/common/uscif/dbgjtag -f %boarddatafile% -rv -o -F inform,logfile=yes -S pathlength -S integrity

    [Result]


    -----[Print the board config pathname(s)]------------------------------------

    C:\Users\silly\AppData\Local\TEXASI~1\CCS\
    ti\0\0\BrdDat\testBoard.dat

    -----[Print the reset-command software log-file]-----------------------------

    This utility has selected a 100- or 510-class product.
    This utility will load the adapter 'jioserdesusb.dll'.

    An error occurred while soft opening the controller.

    -----[An error has occurred and this utility has aborted]--------------------

    This error is generated by TI's USCIF driver or utilities.

    The value is '-151' (0xffffff69).
    The title is 'SC_ERR_FTDI_OPEN'.

    The explanation is:
    One of the FTDI driver functions used during
    the connect returned bad status or an error.
    The cause may one or more of: invalid emulator serial number,
    blank emulator EEPROM, missing FTDI drivers, faulty USB cable.
    Use the xds100serial command-line utility in the 'common/uscif'
    folder to verify the emulator can be located.

    [End: Texas Instruments XDS100v2 USB Emulator_0]

    检查下仿真器驱动是否装好？

    试试重新插拔几次。

    可以看一下是从哪个地方跳进faultISR的。
