C5515 timer interrupt with DSP/BIOS

Marius Herzog

Other Parts Discussed in Thread: TMS320C5515

Hi, I have a Spectrum Digital TMS320C5515 ezDSP on which I want to use timer interrupts using DSP/BIOS. However, my interrupt function is never called, even though the timer interrupt flags in IFR0 and TIAFR are set. My Code is attached. The timer part in the tcf file: bios.CLK.TIMER1FUNC = prog.extern("f"); bios.CLK.TIMERSELECT = "Timer 1"; bios.CLK.CONFIGURETIMER = 0; Thanks in advance

I've got it working now. The bios.CLK.TIMERSELECT selects the primary timer DSP/BIOS uses, so it shouldn't be set to Timer 1. Additionally, A CLK1 object in the clock manager has to be added, pointing to the interrupt function.
