ADI_DSP 201 ----linkport question.

Started by Ebeta February 10, 2007
hi:
   when I use linkport DMA receive data from peripherals,the ACK1
signal is always low.so It can not receive data now.
configuration:
LRCTLx =LRCTL_REN|LRCTL_RDSIZE
When I see ACK1 = low , the LRSTAT of this linkport in ADSP is 0x42.
