Re: -- please someone respond -- S3c2410x (ARM920T) HAL port


No one responded to my previous emails. One way it's good; I getting to know ecos/Reboot underlying code much more elaborately.

The problem I was seeing may be attributed to this (not very sure):
The timer (RTC or tick) interrupt is not happening at all.

Questions:
1. Is this (ISR) needed for proper operation of Redboot (for example for dispatching the gdb command like, ?continue?)?
2. The reason why the interrupt were not happening was, the I bit in CPSR never got cleared (IRQs enabled). The document ?hal-exception-handling.html? in its very 1st point says about interrupts being disabled before starting anything. But never mentioned when its supposed to be turned ON. Someone familiar with the ARM ports; can you tell me where exactly the I bit in CPSR is cleared; this will defiantly make my job easier.


Thanks & Cheers,
-Mike.
