C5402 DSK asm code for codec

Started by Doreen Yeo Lee Guek November 14, 2000
Good day.

1)Just like to find out whether anyone try to hand code in assembly for
C5402 DSK codec example? examples in DSK are C coded and clueless about the
memory mapping, interrupt setting etc.

2) Tried to implement asm code for codec... setup McBSP1 and DMA
ch2(receive) & ch3(transmit) for codec.. DMA ch2 interrupt branch to a FIR
routine...the interrup service routine is working fine but the codec is
enabled even when DSP is halted! then the DSK will crash on me with error as
follows:-

Cc-app
This program has performed an illegal operation and will be shut down.
If problem persists, contact the program vendor.

have you encounter this problem before?

Regards,
Doreen
