I am working on ST25DVXXKC tags with ST25R3916 Reader based application.
Issue: While using ST25R3916_v2.8.0_Linux_demo_v1.1 for raspberry pi, I encountered an issue -> "library compilation failed with undefined symbol".
Cause : As I am using NFC-V technology, I had disabled other technologies in rfal_platfrom.h. e.g.
#define RFAL_FEATURE_NFCA false
Hence function related to other technologies were not available. But for "RFAL Card Detection" in rfal_cd.c rfalCdGetDetectCardStatus function, there are no check for technology defines causing library compilation failed.
Probable Solutions :
1. Add checks for technology according to macros defined e.g.
#if RFAL_FEATURE_NFCA
rfalNfcaPollerInitialize(); /* Initialize for NFC-A */
err = rfalFieldOnAndStartGT(); /* Turns the Field On if not already and start GT timer */
if( err != RFAL_ERR_NONE )
{
gCd.lastErr = err;
gCd.st = RFAL_CD_ST_ERROR; /* Unable to turn the field On, cannot continue Card Detection */
break;
}
gCd.st = RFAL_CD_ST_NFCA_TECHDET;
#else
gCd.st = RFAL_CD_ST_NFCB_INIT; /* Move to NFC-B */
#endif /** #if RFAL_FEATURE_NFCA */
and so on for other technologies.
2. define new macro for RFAL Card Detection feature if card detect feature is not required.
#define RFAL_FEATURE_CARD_DETECT false
in rfal_platfrom.h and use it in rfal-cd.c
Thanks and best reagrds,
