- Subject: [ECOS] Exception handing on The A&M's AdderII board
Dear eCos user:
When I read the interrupt vector from the RAM I saw that the same interrupt
handler function pointer is registered 0x7C7143A6.
The only exception for it had been the first SYSTEM RESET/NMI that had the
0x3C600000 value .
The same had been found for the ROM.
If I understand this right that eCoc uses the same function for handling all
the ISRs (registered in the hal_interrupt_handlers table)
Does anyone know where can I find the code of the 0x7C7143A6 function?
Can someone please explain how does this interrupt arbitration is done in
the AdderII?
Additional info:
My redboot loads my application via TFTP and execute it.
The DCACHE is disabled
I use printf for reading the memory
This is the output I get:
