1) The intro
After finding that the pre-compiled z8530 utils wouldn't work
I went to re-compile them. Unfortunateley they were a bit
unhappy about my glibc2 headers. I've now updated them so
the recompile OK and they seem to work OK. I'll mail the
patch out tonight/tomorrow.
2) The real problem
Unfortunately, the kernel driver doesn't seem so happy. I've just
upgraded from a 2.2.17 kernel to 2.4.4 (without making any
changes to my hardware). I'm using a Baycom USCC4.
Initialisation and configuration using sccinit, sccparam and
ifconfig is fine. The problems come when TX interrupts occur on
two SCC channels at the same time; it locks the whole box hard.
When my machine boots, an rc script configures the devices and
then runs beacon on all ports, which was hanging the box. When
I changed this to beacon on one port only then there were no
problems.
Haven't checked anything to do with RX interrupts yet, so I
can't say whether simultaneous RX ints have the same effect.
Thoughts?
