Currently, I have problem when flashing my custom TX2 board.
My OS: Ubuntu 14.04. I don’t use any virtual machine.
After forcing TX2 board to recovery mode, this is result:
vu@vu-desktop:~$ lsusb

I tried to mount TX2 module from NVIDIA developer kit to our PCB then firmware flashing work well.
I still can not figure out where is problem.
And about the firmware package, I used L4T 28.1 Driver package to flash my board. After finish I can boot to OS properly however my HDMI screen display nothing. On the debug terminal, it shows like above:

This is read-edid version 3.0.2. Prepare for some fun.

Bus 7 doesn't really have an EDID...
Couldn't find an accessible EDID on this computer.
I'm sorry nothing was successful. Maybe try some other arguments
if you played with them, or send an email to Matthew Kern <pyrophobicman@gmail.com>.
Partial Read... Try again
I tried L4T 28.1 Driver package with tegra devkit then everything look working well.
But when I try download firmware with my previous Linux_for_Tegra_tx2 in Jetpack 3.0 for my custom board, HDMI work well.
It only happen on L4T 28.1 Driver package.
According to your previous comment, I make a brief summary. Please make confirmation.
1. Use TX2 + devkit
#HDMI work good on both BSP from Jetpack3.0 and Jetpack3.1.
2. Use TX1 + custom board
#HDMI work good only on BSP from Jetpack3.0 (rel-27.1) but not Jetpacke3.1 (rel-28.1)
3. Use TX1 + devkeit/custom board
#Both work good
1. Use TX2 + dev kit : work well in every case
2. Use TX2 + custom:
+ Jetpack3.0 (rel-27.1): HDMI work well even though I have to plug in/out a few time, network can not start
+ Jetpacke3.1 (rel-28.1): HDMI only show mouse arrow, network work well
I will work around with Jetpacke3.1 (rel-28.1) by ssh to target board. But I hope HDMI will work soon.
And I need to rebuild kernel to support OV10635 image sensor so I hope kernel source rel-28.1 will be update soon.
