Cannot boot from MicroSD card containing Debian Jessie

[Hồng Quân Nguyễn]

Hello

I have an BeagleBone Black with Debian Wheezy preinstalled. I bought an 8GB microSD card and wrote bone-debian-8.3-lxqt-4gb-armhf-2016-01-24-4gb.img image to it (with dd). The writing was complete. I mounted it in Ubuntu laptop to check its content.

Then I plugged the card to BBB to boot it. I'm not sure if it boot successfully or not, but I cannot make LAN connection with it via USB.

What I did to boot it from MicroSD card:

- Power off the BBB.
- Put card in. Hold down the button on top of it.
- Connect USB with my laptop to provide power.
- Wait until 4 LEDs on at once. Wait more 2 seconds and release the button.

I don't have HDMI cable and monitor to see boot process. I tried to make Ethernet Connection with it from Ubuntu but failed. Here is what I see from my laptop syslog

Can you tell me what's wrong and how to fix?

Hi

Update: After trying many times, I can boot the board and SSH to it successfully.
The tip I learn here is to:

- Disconnect wi-fi connection between before connect the board (I don't know if this really help, or just coincidence).
- Wait longer after 4 LEDs on. Can be 5 seconds.

So with 2016-01-24, we had been trying to use the 4.1.x-ti-rt, "Real Time" kernel.  This ended up causing lots of usb problems like what you saw. We've since switched to the non-real-time varient, it's fixed a few of the usb (ethernet/serial) that people where seeing..

If using the USB network emulation, you probably have to wait until the
USB connection is recognized by your host computer. On my system, that
means waiting for Windows to pop-up the "media detected -- what do you want
to do" window. Only then can I use the .7 IP address.

If I've hard-wired via my router, I can probably connect sooner (but
have the annoyance that my router randomly assigns the IP, so I tend to
have to check the router client table to figure out where the BBB ended up
getting assigned).
