sudo ping -i 0.001 -c 1000000 -f 192.168.1.1

This was pinging my router, for about 15 minutes, and I did not get a failed packet, no lockups.

unable to get gpio to work on Raspberry Pi 5 using latest image

Category: Advanced Configuration

It does work, 2 users have had a couple of users have confirmed it.
I've also confirmed myself that loading of the driver as given in the docs also works.

Taking GPIO8 out of the input list allows the driver to load correctly. Which makes sense as GPIO08 as well as GPIO07 seemed to be claimed.

section lifted from gpioinfo
"GPIO7"   "spi0 CS1"  output   active-low [used]
"GPIO8"   "spi0 CS0"  output   active-low [used]

Commenting out spi out in /boot/broadcom/config.txt "fixes" the issue.
