- Bcc:
I try to create a interrupt attach to RTC,but I failed.the code I wrote as
below:
cyg_handle_t timer_intr_handle;
cyg_interrupt timer_intr;
cyg_interrupt_create(CYGNUM_HAL_INTERRUPT_RTC, 1, 0, do_count, 0,
&timer_intr_handle, &timer_intr);
cyg_interrupt_enable();
cyg_interrupt_attach(timer_intr_handle);
I download my code to target, and using GDB(insight) debug my code,.When
program run to the cyg_interrupt_create(...) sentence, the GDB warning me
it "program recieve a signal SIGSEGV, segmentation fault" and then
terminate the program.
please tell me how to solve this problem!thanks in advance!
