Hello,
since some kernel versions I get a kernel errror while setting led trigger to phy0tpt.
command to reproduce: echo phy0tpt > /sys/class/leds/bpi-r2:isink:blue/trigger
same trigger, other led location => no error: echo phy0tpt > /sys/class/leds/bpi-r2:pio:blue/trigger
other trigger, same led location => no error: echo phy0tx > /sys/class/leds/bpi-r2:isink:blue/trigger
last good kernel: bpi-r2 5.19.17-bpi-r2
error at kernel versions: bpi-r2 6.0.19-bpi-r2 up to bpi-r2 6.3.0-rc1-bpi-r2+
Thx for the report.
"5.19.17-bpi-r2" sounds like a vendor kernel. Is that one that is vanilla or at least close to vanilla? If not, you'll have to report this to your kernel vendor. If not: could you try to bisect this?
