Hi, I plugged in a new BB to Linux Mint 18.1, the problem as in topic.
I attach the syslog. Any ideas?

Hi, I have pluggeg in a new BB Black to Linux Mint, once LM 18.1, now some
older version, but the results are similar. The mass device connects
instantly, the leds blink, but there is nothing at 192.168.7.2. I attach
ifconfig, then syslog.
Du you know what might be the problem?

I would guess trhat it is like that: I should reflash the eMMC with
eMMC/HDMI enabled. Then, as rootfs being an image is readonly, I should
download the non-flashing version and boot from it if I want to use the lcd

In principle, everything looks ok:
# set -o | grep history
history on
# echo $HISTFILE
/root/.bash_history
# echo $HISTSIZE
500
# echo $HISTFILESIZE
500
But .bash_history is empty and the history is lost between sessions.

So it means that I can do no-jitter bit banging if only one PRU accesses

The 5V is there until a device is connected. Then it disappears until the
next reset.

When a low-power device is connected, like a mouse, the USB port works. If
a medium-power device is connected, the port switches off until the next
reset.
