Timer triggered GPDMA transfer to SRAM - c

Question

I want to transfer data from an external AD-Converter. I get parallel 11 bits which I store in an array. I wanna set up a timer triggered GPDMA transfer, that every 50ns fires a DMA stream and transfer data. After the transfer is complete, the RAM address should be incremented.
The MCU, I work with is the LPC4088 Quickstart Board.
The CPU and Peripheral Clock, runs with 120Mhz
I studied the UM of LPC4088 and already wrote some simple basic code.
#include "LPC407x_8x_177x_8x.h"
#define PERIPHSRAM1 0x20004000
char adcData[11] = {1,1,1,1,1,1,1,1,1,1,1};
volatile uint32_t DMATCCOUNT = 0;
volatile uint32_t DMAERRCOUNT = 0;
int main(){
uint8_t size = sizeof(adcData);
LPC_SC->PCONP |= (1 << 22); //Power & Clock Timer2
LPC_TIM2->CTCR = (0 << 0); //Timer Mode
LPC_TIM2->PR = 0;
LPC_TIM2->TCR = (1 << 1); //Reset timer
LPC_TIM2->TC = 0;
LPC_TIM2->MR0 = 5; //Match register to get 10MHz
LPC_TIM2->MCR = (1 << 1) //Reset Timer
|(1 << 0); //Interrupt if MR0 matches
LPC_TIM2->EMR = 0x31; //toggle pin to check wave output
LPC_TIM2->TCR = (1 << 1); //reset timer again
LPC_SC->PCONP |= (1 << 29); //Power & Clock DMA
LPC_GPDMACH0->CConfig = 0; //disable CH0
LPC_GPDMA->Config |= (1 << 0); //enable DMA Controller
LPC_SC->DMAREQSEL = 0x010; //Set T2 MAT0 as DMA request
LPC_GPDMA->IntErrClr |= 0x0FF;
LPC_GPDMA->IntTCClear |= 0x0FF;
LPC_GPDMACH0->CDestAddr = PERIPHSRAM1;
LPC_GPDMACH0->CSrcAddr = (uint32_t) &adcData;
LPC_GPDMACH0->CControl = size
|(0x00 << 12) //Source Burst size: 1
|(0x00 << 15) //Destination Burst size: 1
|(0x02 << 18) //Source width: 32 bit
|(0x02 << 21) //Destination width:32 bit
|(0x01 << 26) //Source increment: enabled
|(0x01 << 27) //Destination increment: enabled
|(0x01 << 31); //TermCount interrupt enabled
LPC_GPDMACH0->CControl |= (4 << 1) //Source peripheral: Timer2 MR0
|(0 << 11); //Memory to memory trasnfer
NVIC_SetVector(DMA_IRQn, (uint32_t) DMA_IRQHandler);
NVIC_EnableIRQ(DMA_IRQn);
LPC_GPDMACH0->CConfig |= 1; //Enable channel
LPC_TIM2->IR |= 0x0FF; //CLear all timer interrupts
LPC_TIM2->TCR = 0x01; //start Timer
while(!DMATCCOUNT); //Wait till transfer Complete
while(1){
}
}
void DMA_IRQHandler(void){
uint32_t temp;
DMATCCOUNT++;
temp = LPC_GPDMA->IntTCStat;
if(temp){
DMATCCOUNT++;
LPC_GPDMA->IntTCClear |= temp;
}
temp = LPC_GPDMA->IntErrStat;
if(temp){
DMAERRCOUNT++;
LPC_GPDMA->IntErrClr |= temp;
}
return;
}
I expected data on address 0x20004000, but there is nothing.
Hope any of you guys could help me.
