Spirit1 stuck in PM_setup state (0x3B)

[steport]

Posted on November 26, 2014 at 17:56

Hello,

I try to set up a spirit1 device. I use your given Spiriti1 library and the example projects, but while radiInit, my device stuck everytime on the same point:

SpiritCmdStrobeLockTx();
do{
SpiritRefreshStatus();
}while(g_xStatus.MC_STATE != MC_STATE_LOCK);

This piece of code is located in the

SpiritManagementWaVcoCalibration(void)

function (SPIRIT_Management.c), which gets called during

SpiritRadioInit(&radio);

Instead of going into lock state, the device remains in PM_setup state (0x3B). Do you now why the device behaves like this? However, here is my SRadioInit config:

#define XTAL_FREQUENCY 52000000
#define SPIRIT_VERSION SPIRIT_VERSION_3_0
#define USE_MIDDLE_BAND
#define XTAL_OFFSET_PPM 0
#ifdef USE_VERY_LOW_BAND

#endif
#ifdef USE_LOW_BAND
#define BASE_FREQUENCY 0e6

#ifdef USE_MIDDLE_BAND

#endif

#define CHANNEL_NUMBER 0
#define MODULATION_SELECT FSK
#define DATARATE 38400
#define FREQ_DEVIATION 20e3
#define BANDWIDTH 100E3
#define POWER_DBM 6
#define RSSI_THRESHOLD 0x20
/** SPIRIT Radio configuration struct */
static SRadioInit radio;
radio.nXtalOffsetPpm = XTAL_OFFSET_PPM;
radio.lFrequencyBase = BASE_FREQUENCY;
radio.nChannelSpace = CHANNEL_SPACE;
radio.cChannelNumber = CHANNEL_NUMBER;
radio.xModulationSelect = MODULATION_SELECT;
radio.lDatarate = DATARATE;
radio.lFreqDev = FREQ_DEVIATION;
radio.lBandwidth = BANDWIDTH;

Hello,

to be able to aswer to your question, we need more information, and to start:

1. are you using our evaluation board?
2. which frequency band you are working with?
3. what crystal are you using?

Regards,

Gaetano

Hello,

Thank you for your answer.

I'm using your Spirit1 chip and radio circuit from your eval board attached to my custom board. http://www.st.com/web/en/catalog/tools/PF253894

I'm working on 433MHz frequenzy and the I have Spirit eval boards with 50MHz or 52MHz crystal. The described problems happens with both crystal frequency.

Best regards

Hello,

do you call the following:

SpiritRadioSetXtalFrequency(XTAL_FREQ);

before radio init?

(obviusly XTAL_FREQ is 50000000 or 52000000 according to your xtal).

PS: http://www.st.com/web/en/catalog/tools/PF253894 links to a 315MHz board. Is this link correct, given that you are working at 433MHz?

Regards,

Gaetano

Hello,

Yes, I do call SpiritRadioSetXtalFrequency(XTAL_FREQ); before init. and I change the XTAL_FREQ according to my crystal. The modulues working on 433Mhz, the according resistor is set. Here is my init code:

void rfProtocolInit(void){
uint32_t i;
rf_protocol_state = Init;
//Resets Spirit1
SpiritEnterShutdown();
for(i=0;i<100000;i++);
SpiritExitShutdown();
for(i=0;i<100000;i++);
/** \brief SPIRIT Gpio configuration. */
gpio0.xSpiritGpioIO = SPIRIT_GPIO_0;
gpio0.xSpiritGpioMode = SPIRIT_GPIO_MODE_DIGITAL_OUTPUT_LP;
gpio0.xSpiritGpioPin = SPIRIT_GPIO_DIG_OUT_IRQ;
gpio1.xSpiritGpioIO = SPIRIT_GPIO_0;;
gpio1.xSpiritGpioMode = SPIRIT_GPIO_MODE_DIGITAL_OUTPUT_LP;
gpio1.xSpiritGpioPin = SPIRIT_GPIO_DIG_OUT_SYNC_DETECTED;
SpiritGpioInit(&gpio0);
SpiritGpioInit(&gpio1);
/** \brief SPIRIT Radio configuration */
radio.nXtalOffsetPpm = XTAL_OFFSET_PPM;

radio.lDatarate = DATARATE;
radio.lFreqDev = FREQ_DEVIATION;
radio.lBandwidth = BANDWIDTH;
SpiritRadioSetXtalFrequency(XTAL_FREQUENCY);
SpiritRadioInit(&radio);

packet.cPktLengthWidth = 6; //log2(MAXPAYLOADLENGTH+1) = log2(64) = 6
packet.xCrcMode = PKT_CRC_MODE_8BITS;
packet.xControlLength = PKT_CONTROL_LENGTH_0BYTES;
packet.xAddressField = S_DISABLE;

packet.xDataWhitening = S_DISABLE;
addresses.cBroadcastAddress = 255;
addresses.cMulticastAddress = 100;
addresses.cMyAddress = MyAddress;

Hello,

we have used your code with our daughter board but the issue was not reproduced.

Can you report the value of the registers f0 and f1?

Regards,

Gaetano

Hello,

I've read all Spirit registers before radioInit() and on failure I read it again. Therefore it's possible to check the register access. I observed many data conversions and probably there it fails.. I'm checking this. Here is my report:

Hello,

I don't see anything wrong in those registers values.

The way we have reproduced your issue has been to use a board with a 26MHz crystal instead of the 52MHz one. Thus, a couple of question:

- do you use the GUI to obtain the crystal frequency? If not, how do you obtain this info?

- can you comment the call to the following function (at the end of the radioinit function):

SpiritManagementWaVcoCalibration

and report what happens.

Regards,

Gaetano

Hello,

I obtained the crystal frequency by reading the label with a magnifying glass, it's very small but readable.

I commented the SpiritManagementWaVcoCalibration function as you wrote. In my library sources, this funtion gets called in SpiritRadioSetFrequencyBase function, which gets called at the end of radioInit. (SPIRIT_Radio.c / line944).

Now the device finishes intialisation. Packet and address config works and it goes into ready state.

After initialisation i tried getting into LockTX state. I called SpiritCommandStrobes(0x66) and the device stucks in 0x3B state.

Do you have any ideas why this happens?

Thank you

Kind regards
