As title.
I'm trying to write a flash write routine using DAM method for my CC2510F32.My code is below:
#include <ioCC2510.h>
#include <ioCCxx10_bitdef.h>
#include <hal_types.h>
#include <dma.h>
/* One whole page of flash memory is to be reserved, i.e., 1 KiB. */
#define PAGE_SIZE 1024
/* String length (exluding the terminal '\0'). */
#define DATA_AMOUNT 16
/* The "string" to be written to flash ('\0' not included). */
static const char data[DATA_AMOUNT] = "Flash Controller";
static char writeCheck[DATA_AMOUNT];
unsigned char c=0;
__no_init const char __code flashDataAddr[PAGE_SIZE] @ 0x4400;
/* DMA configuration descriptor used for flash write. */
static DMA_DESC dmaConfig0;
/*******************************************************************************
* LOCAL FUNCTIONS
*/
// Prototype for local functions (implemented in assembly).
void halFlashStartErase(void);
void halFlashStartWrite(void);
int main(void)
{
// DMA_DESC dmaConfig0;
P1SEL = 0x00;
P1DIR = 0x03;
P1_0 = 0;P1_1 = 0;
dmaConfig0.SRCADDRH = ((uint16)data >> 8) & 0x00FF;
dmaConfig0.SRCADDRL = (uint16)data & 0x00FF;
dmaConfig0.DESTADDRH = ((uint16)&X_FWDATA >> 8) & 0x00FF;
dmaConfig0.DESTADDRL = (uint16)&X_FWDATA & 0x00FF;
dmaConfig0.VLEN = DMA_VLEN_USE_LEN;
dmaConfig0.LENH = (DATA_AMOUNT >> 8) & 0x00FF;
dmaConfig0.LENL = DATA_AMOUNT & 0x00FF;
dmaConfig0.WORDSIZE = DMA_WORDSIZE_BYTE;
dmaConfig0.TMODE = DMA_TMODE_SINGLE;
dmaConfig0.TRIG = DMA_TRIG_FLASH;
dmaConfig0.SRCINC = DMA_SRCINC_1;
dmaConfig0.DESTINC = DMA_DESTINC_0;
dmaConfig0.IRQMASK = DMA_IRQMASK_DISABLE;
dmaConfig0.M8 = DMA_M8_USE_8_BITS;
dmaConfig0.PRIORITY = DMA_PRI_HIGH;
DMA0CFGH = ((uint16)&dmaConfig0 >> 8) & 0x00FF;
DMA0CFGL = (uint16)&dmaConfig0 & 0x00FF;
/* Waiting for the flash controller to be ready */
while (FCTL & FCTL_BUSY);
FWT = 0x22;
//FADDRH = (int)flashDataAddr >> 9;
//FADDRL = ((int)flashDataAddr >> 1) & ~0xFF00;
FADDRH = (int)flashDataAddr >> 8;
FADDRL = ((int)flashDataAddr ) & 0x00FF;
DMAARM |= DMAARM0;
/* Erase the page that will be written to. */
FCTL = 0x01;
asm("NOP");asm("NOP");asm("NOP");asm("NOP");asm("NOP");asm("NOP");
asm("NOP");asm("NOP");asm("NOP");asm("NOP");asm("NOP");asm("NOP");
asm("NOP");asm("NOP");asm("NOP");asm("NOP");asm("NOP");asm("NOP");
asm("NOP");asm("NOP");asm("NOP");asm("NOP");asm("NOP");asm("NOP");
asm("NOP");asm("NOP");asm("NOP");asm("NOP");asm("NOP");asm("NOP");
asm("NOP");asm("NOP");asm("NOP");asm("NOP");asm("NOP");asm("NOP");
/* Wait for the erase operation to complete. */
while (FCTL & FCTL_BUSY);
/* Arm the DMA channel, so that a DMA trigger will initiate DMA writing. */
DMAREQ |= DMAREQ0;
P1_0 = 1;
/* Enable flash write. Generates a DMA trigger. Must be aligned on a 2-byte
* boundary and is therefor implemented in assembly.
*/
FCTL |= 0x02;
/* Wait for DMA transfer to complete. */
while (!(DMAIRQ & DMAIRQ_DMAIF0));
//while (!(DMAIRQ & 0x01));
P1_1 = 1;
/* Wait until flash controller not busy. */
while (FCTL & (FCTL_BUSY | FCTL_SWBSY));
/* By now, the transfer is completed, so the transfer count is reached.
* The DMA channel 0 interrupt flag is then set, so we clear it here.
*/
DMAIRQ &= ~DMAIRQ_DMAIF0;
/* Read from flash to check whether the write was successful. */
uint8 i;
for (i = 0; i < DATA_AMOUNT; i++)
{
writeCheck[i] = flashDataAddr[i];
}
return 0;
}
I use its sample code, but always stop in below code:
" while (!(DMAIRQ & DMAIRQ_DMAIF0)); /* Wait for DMA0 transfer to complete. */ "
And I don't know " halFlashStartErase(); " and " halFlashStartWrite() ", what's these content of sub routine?
In my code,these content of sub routine is my guess.
I search the other related subject of anyone, and anyone say use sample code is OK.
But I use sample code is wrong.
I must need to learn to use FLASH Write and Erase.
Please help me.
Thanks a lot.
