刚唤醒又进去了休眠?意思是无法唤醒?

回复 user5164010:

是否有参考过下面的帖子?

user5164010:

回复 Shine:

问题应该不是相同的,不过我可以尝试下更新休眠唤醒固件。只是我不知道怎么去更新,那个固件包是适合我目前的sdk的

user5164010:

回复 Shine:

我仔细的看了一下,am335x-pm-firmware.bin这个固件的功能好像解决的不是我这样的问题

user5164010:

回复 Shine:

你们能尽量帮我快点解决这个问题吗?量产在即。麻烦了

user5164010:

有人可以帮我吗

user5164010:

偌大的TI论坛没有人了吗,TI工程师都死了吗

Shine:

回复 user5164010:

抱歉,因TI为没有android的支持资源,现在已经完全交给witekio来支持了。witekio.com/…/Android software development kitwww.ti.com/…/tools-software.html

另外,我在e2e上发了个帖子,可以关注一下。
