Problem in Interrupt Enable process

since working with RTX, to enable interrupt should be operated by os_enable_isr(), and directly setting bit in IE is no useful......but, the problem is why it failed to call os_enable_isr(4) to enable serial port0 interrupt.......anybody can give me some advice on it. thanks in advance.

  • According to the result of trace, it failed when to check a base-address add the specified interrupt number, the address(in Code address) return 0, then it return fail information.......why did it return fail? what should I put in the address? any other way to enable interrupt except the RTX function os_enabled_interrupt()?
