Hello everyone,
I have a problem about EQADC streaming mode.
When I write one command to CFIFO by setting REP and PAUSE bit on same command for streaming mode, I can receive data correctly on each trigger.
However, when I write two commands to CFIFO by setting REP on first command and setting PAUSE on second command, I cannot receive any data.
Which point could I ignore?
You can find my a part of my code below.
void eDMA_Init_Receive(DMA_Type* dma, uint32_t channel, uint32_t *sourceAddr, uint32_t *destAddr, uint32_t ByteCount)
{
// SOURCE ADRESS
dma->TCD[channel].SADDR = (uint32_t)sourceAddr;
// SMOD AND DMOD ARE 0
// SSIZE AND DSIZE ARE 8 BIT (0X0)
dma->TCD[channel].ATTR = 0x0000;
// SOFF IS 1 BYTE. AFTER COMPLETING ONE TRANSFER, THIS IS ADDED TO SADDR
dma->TCD[channel].SOFF = 1;
// NBYTE
dma->TCD[channel].NBYTES.MLNO = ByteCount;
// SLAST IS -400. THIS VALUE IS USED TO RETURN SADDR TO FIRST ADRESS VALUE
dma->TCD[channel].SLAST = -ByteCount;
// DESTINATION ADRESS
dma->TCD[channel].DADDR = (uint32_t) destAddr;
dma->TCD[channel].DLASTSGA = -ByteCount;
// THE NUMBER OF MAJOR LOOP
dma->TCD[channel].CITER.ELINKNO = 1;
// DOFF IS 1 BYTE. AFTER COMPLETING ONE TRANSFER, THIS IS ADDED TO DADDR
dma->TCD[channel].DOFF = 1;
// BITER IS EQUAL TO CITER. AFTER CITER REACHES O, CITER WILL BE EQUAL BITER AGAIN.
dma->TCD[channel].BITER.ELINKNO = 1;
dma->TCD[channel].CSR = 0;
dma->ERQL |= (0x1<<channel);
dma->CR = 0xC;
}
SIU->ISEL5 = 0x20000;
SIU->ISEL9 = 0x50000;
EQADC_0->CFCR0 = 0X0C550000;
EQADC_0->IDCR0 |= (1<<29);
EQADC_0->IDCR0 |= (1<<17);
EQADC_0->IDCR0 |= (1<<16);
EQADC_0->IDCR0 |= (1<<1);
EQADC_0->IDCR0 |= (1<<0);
EQADC_0->CFPR[0] = 0x20000000;
EQADC_0->CFPR[0] = 0x44100100;
eDMA_Init_Receive(DMA_0, 1, 0xFFF80030, &value, 4);
eDMA_Init_Receive(DMA_0, 3, 0xFFF80034, &value1, 4);
