Re: Re: On ARM7 can one of FIQ/IRQ be used for non-eCos stuff?

It already exists.

void cyg_interrupt_get_vsr(cyg_vector_t vector, cyg_VSR_t** vsr);

void cyg_interrupt_set_vsr(cyg_vector_t vector, cyg_VSR_t* vsr);

with the vector CYGNUM_HAL_VECTOR_FIQ.

The vsr function needs to be written in assembly and save and restore
all registers etc.
