RTOS/TCI6630K2L: FFTC - Interrupts

Part Number: TCI6630K2L


Tool/software: TI-RTOS

hi,

Im working with the FFTC module, and it is configured such that it works in a while(1) loop. This works fine when the IQNET configuration is Disabled , and in real time when the IQNET configuration is enabled and

  a) FFTC instance 0 is Configured ->  i could receive  only 3 interrupts  and the 4th interrupt is not coming up .

  b) if Both FFTC instance 0 and 1 are used alternatively then -> i was able to receive 6 interrupts and the 7th interrupt is not coming up. i.e(3 interrupts for each FFTC Instance, 4th interrupt is not coming up) .

1) Accumulator Configuration of FFTC instance 0:

AccChannelNum = 0;
AccRxQNum       = 704;

eventId = 48;
vectId   = 8;

2 ) Accumulator Configuration of FFTC instance 1:

AccChannelNum = 8;
AccRxQNum       = 708;

eventId  = 49;
vectId    = 8;

Regards
