您好:
我正在使用AM2634-LP开发板集成OTP Keywrite功能,在集成过程中有以下疑问请您解答下:
问题1:我是在windows环境下操作,在设置编译环境中,解压缩完成am263x-cc.zip压缩包后,文档提示的是需要执行gmake env.sh操作,但是解压缩之后的没有env.sh文件如下图所致,请问此时应该如何设置?
问题2:在SOC上运行时,要求VPP必须通电,我方使用的是AM2634-LP开发板,请问有没有AM2634-LP开发板给VPP通电的说明?
问题一是我自己没有添加环境变量导致的,目前已解决
非常感谢分享解决方法!

请看下面的说明。
As this VPP pin is not used in the functional mode, the pin needs to be enabled while only writing to the eFuse and disable rest of the time. A simple way like having a LDO which can be controlled using a GPIO of AM263x can be used here, Whenever the eFuse programming is needed enable the LDO. The output of LDO can be used to feed 1.7V VPP line. Please have look at TLV70717 LDO.
AM263X-LP开发板上的VPP悬空不接的。请看下面网站上的开发板原理图。
