Hello,
I have been running some tests using embedded linux (specifically raspberry pi) to switch a relay off and back on with specific timing. I have been having trouble with the timing being a bit unreliable and when I time my script there is huge different between the real time and user time...
Is it possible if I run echo u > /proc/sysrq-trigger to get the linux back to the same state it was before without waiting for a restart. My use case is an embedded linux system that needs to deal with sudden (though with short notice because of supercapacitors) loss of power, and possibly...
