CC1310: when rx got the SYNC signal (RFHWIFG.MDMSOFT = 1), any idea to make sure the radio cpu will set the RFCPEIFG.RX_ENTRY_DONE, even tx stop transmit ?

WH HUANG

Part Number: CC1310

1. fixed packet length,

2. no address checking.

My settings as follow shows:

RF_cmdPropRx.rxConf.bAutoFlushCrcErr  = 0;
                RF_cmdPropRx.rxConf.bAutoFlushIgnored = 0;
                RF_cmdPropRx.pktConf.bChkAddress      = 0;
                RF_cmdPropRx.pktConf.bRepeatNok       = 0;
                RF_cmdPropRx.pktConf.bRepeatOk        = 0;

it is that ok ? 

our system need a hopping function.

for my testing:

when the device works over a few minutes (10-30mins), it stop works. and then I found before stop the device was found the SYNC signal (MDMSOFT = 1), but the radio cpu never set the 
RFCPEIFG.RX_ENTRY_DONE;  and

RF_cmdPropRx.status = 0x0x3400, //Operation ended normally

RF_cmdFs.status = 0x0809;  //Synthesizer programming failed.

Advisory Synthesizer Calibration Might Fail on Rare Occasions
Description The synthesizer (synth) calibration has been observed to fail on rare occasions. This will
cause any radio command that requires a calibrated synth to fail.

If the calibration of the synth fails the radio will not be able to enter TX or RX state. Please see http://processors.wiki.ti.com/index.php/CC1310_rev_B_PCN_information#Re-starting_radio_operations_in_case_of_failures for how this can be handled.

Ok， Just fixed this issue... but why RF_cmdPropRx.status value is NOT PROP_ERROR_NO_FS?

You will get ERROR_NO_FS (0x0808) if you try to go to TX or RX without having done a CMD_FS. If you have done CMD_FS, and it fails, you will get ERROR_SYNTH_PROG (0x0809)

Ok ,thanks.
as follow code shows: so the radio CPU do NOT execute RF_cmdPropRx this command,right ?
RF_cmdFs.pNextOp = (rfc_radioOp_t *)&RF_cmdPropRx;
RF_cmdFs.condition.rule = COND_ALWAYS;

The radio will not be able to enter RX if the synth calibration has failed.
