External flash in Sensor Tag cc2650stk

Hi, sorry for my stupid question

Why sensor test for external flash does not execute success?

Project SensorTag has this code:

static void SensorTag_init(void)
{ 
.....
// Power on self-test for sensors, flash and DevPack
  selfTestMap = sensorTestExecute();  //selfTestMap=0x3f;
  
  if (selfTestMap == ST_TEST_MAP)
  {
    SensorTag_blinkLed(Board_LED2,TEST_INDICATION_BLINKS);
  }
  else
  {
    SensorTag_blinkLed(Board_LED1,TEST_INDICATION_BLINKS);
  }
...
}

When I come in sensorTestExecute()->...->extFlashVerifyPart(): bspSpiWrite(wbuf, sizeof(wbuf)) returns true, and bspSpiRead(rbuf, sizeof(rbuf)) returns true. But realy rbuf contains 0x00 and function extFlashVerifyPart returns false.
I trying configured SPI :

/* SENSORTAG_CC2650_SPI0 */
        .baseAddr = SSI0_BASE,
        .intNum = INT_SSI0,
        .defaultTxBufValue = 0,
        .powerMngrId = PERIPH_SSI0,
        .rxChannelBitMask = 1<<UDMA_CHAN_SSI0_RX,
        .txChannelBitMask = 1<<UDMA_CHAN_SSI0_TX,
        .mosiPin = Board_SPI0_MOSI,
        .misoPin = Board_SPI0_MISO,
        .clkPin = Board_SPI0_CLK,
        .csnPin = Board_SPI_FLASH_CS <--

but it is does not help.

There is a situation during debugging when you may encounter a problem with the external flash. This is because SPI clock is shared with one of the debugger signals. The solution in this case is to power cycle the board and you should be okay. When running on batteries this is of course never a problem.

Hi Jomar,

Someone should really add this info as a warning to the documentation :)

Thanks for your answer again.
