KL16 mcu SPI read/write NandFlash failure

junwang1 — Fri, 01 Jul 2016 07:13:49 GMT

I use below code to read ID of external NandFlash . The code is generated under KDS's PE tool.Every operation returns a wrong result. 0xFF, 0xC8. The right result should be 0xC8, 0xD4. I test sck output wave, should output 32 clock pulses, but really only output 16 clock pulses.

....................................

txbuf[0] = 0x9F;

txbuf[1] = 0x00;

SM2_ReceiveBlock(SM2_DeviceData, recv_buf, 2);

SM2_SendBlock(SM2_DeviceData, txbuf, 2);

while (!SM2_GetBlockReceivedStatus(SM2_DeviceData))

{

SM2_Main(SM2_DeviceData);

}
