From: iceman1001 Date: Fri, 23 Sep 2016 19:28:07 +0000 (+0200) Subject: FIX: "hf 14a read" / "hf mf *" / "hf mfdes info" and failure when calling these... X-Git-Url: http://cvs.zerfleddert.de/cgi-bin/gitweb.cgi/proxmark3-svn/commitdiff_plain/f885043422facc34eb6a5b3c3767f8ac25338157?hp=9bd1640803a4318ed589dbddb19aada36b2a02c0 FIX: "hf 14a read" / "hf mf *" / "hf mfdes info" and failure when calling these commands serveral times in row. For long transactions the sspclock compare with >1 instead of >=1 .. Now the timer resets properly. CHG: use some #define constants for iso-commands. --- diff --git a/armsrc/iso14443a.c b/armsrc/iso14443a.c index 26781095..5a43e233 100644 --- a/armsrc/iso14443a.c +++ b/armsrc/iso14443a.c @@ -1835,10 +1835,10 @@ int ReaderReceive(uint8_t *receivedAnswer, uint8_t *parity) { // if anticollision is false, then the UID must be provided in uid_ptr[] // and num_cascades must be set (1: 4 Byte UID, 2: 7 Byte UID, 3: 10 Byte UID) int iso14443a_select_card(byte_t *uid_ptr, iso14a_card_select_t *p_hi14a_card, uint32_t *cuid_ptr, bool anticollision, uint8_t num_cascades) { - uint8_t wupa[] = { 0x52 }; // 0x26 - REQA 0x52 - WAKE-UP - uint8_t sel_all[] = { 0x93,0x20 }; - uint8_t sel_uid[] = { 0x93,0x70,0x00,0x00,0x00,0x00,0x00,0x00,0x00}; - uint8_t rats[] = { 0xE0,0x80,0x00,0x00 }; // FSD=256, FSDI=8, CID=0 + uint8_t wupa[] = { ISO14443A_CMD_WUPA }; // 0x26 - ISO14443A_CMD_REQA 0x52 - ISO14443A_CMD_WUPA + uint8_t sel_all[] = { ISO14443A_CMD_ANTICOLL_OR_SELECT,0x20 }; + uint8_t sel_uid[] = { ISO14443A_CMD_ANTICOLL_OR_SELECT,0x70,0x00,0x00,0x00,0x00,0x00,0x00,0x00}; + uint8_t rats[] = { ISO14443A_CMD_RATS,0x80,0x00,0x00 }; // FSD=256, FSDI=8, CID=0 uint8_t resp[MAX_FRAME_SIZE] = {0}; // theoretically.
