I am using spi 1 of kinetis k70 (connected to spi nor)
I am trying to read manufacturer id of spi nor ,
For this i have to write "9f" to spi nor and it will written manufacturer id ,but i am able to read the data
I have used the example given in help
and used spi and consoleio components from processor expert
#include "Cpu.h"
#include "Events.h"
#include "SM1.h"
#include "CsIO1.h"
#include "IO1.h"
/* Including shared modules, which are used for whole project */
#include "PE_Types.h"
#include "PE_Error.h"
#include "PE_Const.h"
#include "IO_Map.h"
#define BLOCK_SIZE 4uint8_t OutData[BLOCK_SIZE] = "9F";
uint8_t InpData[BLOCK_SIZE];
volatile LDD_SPIMASTER_TError ComError = 0U;
LDD_TError Error;
LDD_TDeviceData *MySPIPtr;
int main(void)
{
/*** Processor Expert internal initialization. DON'T REMOVE THIS CODE!!! ***/
PE_low_level_init();
/*** End of Processor Expert internal initialization. ***/
MySPIPtr = SM1_Init(NULL); /* Initialization of SM1 component */while(1){
SM1_SelectConfiguration(MySPIPtr, 1U, 1U); /* Select chip select 0 and attribute set 0 */
Error = SM1_ReceiveBlock(MySPIPtr, InpData, BLOCK_SIZE); /* Request data block reception */
printf("Receive --> %x\n",InpData);
Error = SM1_SendBlock(MySPIPtr, OutData, BLOCK_SIZE); /* Start transmission/reception */
while (!SM1_GetBlockReceivedStatus(MySPIPtr)) { /* Wait until data block is transmitted/received */
SM1_Main(MySPIPtr);
}
}
#ifdef PEX_RTOS_START
PEX_RTOS_START(); /* Startup of the selected RTOS. Macro is defined by the RTOS component. */
#endif
/*** End of RTOS startup code. ***/
/*** Processor Expert end of main routine. DON'T MODIFY THIS CODE!!! ***/
for(;;){}
/*** Processor Expert end of main routine. DON'T WRITE CODE BELOW!!! ***/
} /*** End of main routine. DO NOT MODIFY THIS TEXT!!! ***//* END main */

So when i print i get Receive --> 1fff00d8
which is some wrong value ,ii think i am not reading correctly,what should i change in the program to do it

Hi,
Could you provide more info about the SPI NOR Flash part number?
And if possible, could you post the Processor Expert code for double check?
Have a great day,
