- Subject: [ECOS] SH4 Interrupt Handling
Hi,
I have a small probleming trying to set up
the interrupt handling......I am working on an SH4 processor(SH7751)
I am trying to write a monitor program...
In the entry point of my program...which is loaded at 0x8c020000 (RAM)
I set the VBR to ( a Interrupt Handler function address - 0x0000600) (..The
Interrupt handling is the same as in SH3...)
As such now when an interrupt occurs my Handler function should be called...
I realize that I need to set up the INTC et al...but am quite ignorant about
that...
Can u help me detaling the step by step intialization procedure....
I am using REDBOOT to run my proram...soon after I change the VBR....a reset
occurs and control goes back to the REDBOOT Monitor program....
What am I missing out???
Thanks,
Kiran
