Jetson TX1 module don't work on Self-developed Carrier Boad !!!

Hi Trumany,
I’m Wance.My colleague sent a post as follows,
Topic:Self-developed Carrier Boad of Jetson TX1 Can’t Power on
Adress:https://devtalk.nvidia.com/default/topic/972030/jetson-tx1/self-developed-carrier-boad-of-jetson-tx1-can-t-power-on/1

But now,I find Some problems of Power Up Sequence.As you know,we have core modules for two types.My test is following,
1、My Reset Circuit : http://p1.bqimg.com/1949/39e5ee3b2c7dce4f.jpg
2、Power Up Sequence from PDF : http://p1.bqimg.com/1949/bb0ca04ae8956233.jpg

stuffed R17:(The picture of power up sequence digram are PWR_BTN and Reset_Out#)
3、demo core module + self-developed carrier board : http://p1.bpimg.com/1949/f4bb0ed76cb256b6.jpg
4、bought core module + self-developed carrier board : http://i1.piimg.com/1949/5d893eccdd58f4c7.jpg

unstuffed R17:(The picture of power up sequence digram are PWR_BTN and Reset_Out#)

6、bought core module + self-developed carrier board : http://i1.piimg.com/1949/a2094217ef32114f.jpg

My question:
A、From 2 point Power Up Sequence,what is the signal of Carrier Board System Power? It look likes the signal of Carrier Board System Power causes RESET_OUT# mistaking.
B、After self-developed carrier board powers up, I get 5.0 voltage、3.3 voltage、1.8 voltage.But,If I need to connect any signal on carrier board to core module pins to indicate that the System Power on carrier board have worked?
C、Untsuffed R17,although the Reset_Out# can be 1.8 voltage,but it takes 75ms from 0 to 1.8 voltage.So,If the core module detects some error about core module state during this time and then the Reset_Out# outputs error ?

I hope to get your help. Thanks very much.

Please refer to this topic which i think is from you too
