Re: Pi4 64-bit raspbian kernel for testing - Focus on Pi4

It looks with this P4 64-bit Kernel, raspistill and raspivid don't work properly. Even **^C** and **^Z** won't be able to halt the camera application. Did anybody meet the same issue? pi@pi01:~ $ raspistill -o cam.jpg Message from syslogd@pi01 at Jun 10 17:45:42 ... kernel:[ 236.233099] Internal err...

Re: Raspberry Pi 4 no input, black screen

This happened to me twice already. What I've done is

Code: Select all

sudo reboot
from ssh

and, my Raspberry Pi 4 seems still bootable, but ONLY but into a black screen.

From remote, neither ssh nor ping is working again.


Can anybody give me some suggestions?

Thank you very much

Raspivid crashes network connection.

Hi, all:

Environments:
Board: Raspberry PI B
OS: RASPBIAN
Debian Wheezy
2014-09-09

Symptom:

Code: Select all

raspistill -o image.jpg
works perfectly for me, but

Code: Select all

raspivid -o vid.h264 -t 10000
always stops my network connection via ssh

Is this a bug for current RPI ?
