CCS : v6

OS : win 7 x64

SYS/BIOS : 6_40_02_27

xdctools : 3_30_02_44_core

board : Zoom OMAP-L138 EVM Development Kit (LOGIC PD)

In order to controlling PWM, I try to apply hwi. when i made project, i choose C6000 complier to work on DSP part.

Left side is DSP interrupt assignment of OMAP-L138(datasheet). number 18 is ehrPWM1. but right side of figure is shown 'ti.sysbios.family.c64p.Hwi/interrupt: indx out of range'.

I think that this problem has occurred because I skipped some important file or I incorrectly set to HWI-instance setting.

Other sysbios propertis are used as well. please help to apply hwi~?

Hi Seo,

Please post your BIOS related queries in TI RTOS forum.

Here we can discuss the device specific problems, starterware and CSL packages queries.

Please refer the TI E2E thread which similar to yours and it may help to solve your problem.

Hi,

Thanks for your post.

I am seeing the c6748 DSP core of OMAPL138 interrupt no. but on the right side, i am seeing the same interrupt number is mapped to c64p HWI instance settings. How it is possible? Kindly clarify the same and i think, you have to recheck your HWI configuration for the right c6748 core.

We do not have C64p core in OMAPL138 instead, you have c6748 DSP core. Please check it.

Thanks & regards,

Sivaraj K

Hi Seo,

I found problem in interrupt no.

You have to use "EVT#" 18 in "Event Id" box and not in interrupt no.

Please mention '18' PWM event ID in "Event Id" box and mention interrupt no as '1' if you have only one interrupt.

Have you tried to configure the HWI through code and not through GUI ?

Also you can refer the facdetect demo code for HWI in OMAPL138 boards.
