Hi, This is with regard to a problem that we are facing with our DSP TMS320C6416 , version E. The external interrupt 5 , which is multiplexed with GPIO pins is used in order to provide event synchronisation to the Edma.We have configured the GPEN=0xF9 and GPVAL=0xF9.This would mean that GPIO5 is enabled to function as a GPIO , when , in fact we need it to be an external interrupt.The application doesnt work when GPEN=0xD9. Also, the code works perfectly when run on the emulator , but fails to work when booted from flash. Is there any regiser configuration that we have missed out?Also , what are the exact configurations to be done to configure the external interrupt 5? Awaiting a reply at the earliest. Thanks and best regards, ramya |
