Hi everyone,
I'm dealing with an embedded Linux, where an application opens the
/dev/spidev1.0 device and constantly talks through with another MCU.
Now if I I try to look at what exchanges (that's what I'd need), doing
a hexdump /dev/spidev1.0 shows something in the beginning but causes
the application to crash. The app is very sensitive and I think it crashes
because the app uses and it can't be used for viewing simultaneously.
Would there be a way to create an alias, or something like a mirror of
this device if I write some extra code/driver? Or is there no chance for
me to sniff the traffic like that (in software) ?
Many thanks in advance!
Alex
