SSP DMA on LPC2387

Started by Johann Zimmermann May 12, 2009
Hello all users!

Has anyone used the SSP DMA on LPC32XX?
I compiled a SSP sample project from IAR Compiler. It sends 256 bytes DMA channel0.
If I change the DMA_SIZE from 256 to 32 - it makes no difference.
/* Terminal Count Int enable */
GPDMA_CH0_CTRL = (DMA_SIZE & 0x0FFF) | (0x02 << 12) | (0x02 << 15)
| (1 << 26) | 0x80000000;
Can please somebody help me!
