- Subject: [ECOS] ISR not causing an DSR in some rare conditions
Hi,
i'm using XScale PXA270 processor with latest eCos and I think I found a
problem with DSR's. I'm 100% sure that there must be a condition where eCos
not calls the DSR of an interrupt. I have a IRQ which comes 45 times a
second on a system running at high load. After more then 10 hours one DSR
is missing. This is a bad situation which makes the system unstable.
Is this problem known? Maybe it depends only on the architecture (ARM).
Would it be a good idea to contact ecoscentric for a solution?
Bye...
