Using C6748 StarterWare 1.20.02.02
In peripheral DMA_MODE I call doDmaTxTransfer() (cppi41dma.c) which finishes with a call to pushToSubmitQ which submits a BD to the Queue Manager Queue N Control Register D = 0x01e00000+0x600C+(queue<<4)
The next step is a call to enableCoreTxDMA() which clears the PERI_TXCSR AUTO_SET bit then sets the DMAMODE and DMAEN bits. As I understand this is the point where the transmission should start.
But, I get an interrupt indicating that the transmission is complete before the call to enableCoreTxDMA(). This means that the packet was sent by the DMA while DMAMODE==DMAEN==0
How can this be?
