环境：ccs Version: 6.2.0.00050 ，beaglebone black板子，通过jtag链接，仿真器为XDS100V2
调试processors.wiki.ti.com/.../PRU_Training:_Hands-on_Labs，例子一。
按文档说明进行配置PRU_CAPE.gel (文件位于pru sdk v4.0.2的<PRU_SW_PATH>/pru_cape目录下).
问题1：
jtag连接目标板正常，按文档
Run the GEL script under Scripts->Initialization->PRU_Cape_Init.
无法找到这步操作。
问题2：
点击菜单Scripts->PRU_CAPE->PRU_Cape_Init后，报错。内容如下：
CortxA8: Output: ****** PRU Cape PINMUX is being configured *****
PRU_Cape_Init() cannot be evaluated.
Could not write 0x44E10990: execution state prevented access
at *((unsigned int *) 0x44e10990)=(0|5) [PRU_CAPE.gel:40]
at PRU_PINMUX_Config() [PRU_CAPE.gel:25]
at PRU_Cape_Init()
请帮忙指导解决下问题，非常感谢！
