* rework iso14443b device functions
* hf_read_rx_xcorr.v: transfer i/q pair in one 16bit frame
* hi_read_tx.v: invert ssp_dout. When nothing is transferred (ssp_dout=0), this results in no modulation (carrier on)
* adjust arm sources accordingly
* iso14443b.c: switch off carrier after hf 14b sri512read and hf 14b srix4kread
* iso14443b.c: fix DMA circular buffer handling
* move to separate files mifaresim.[ch]
* check CRC of commands
* don't execute commands without successfull authentication
* ensure correct timing of REQA, WUPA, ANTICOL and SELECT responses
* trace reader commands immediately, only fix start time after tag response. Decreases time to be ready for next reader command.
* remove iso14443-4 remnants
* trace raw reader commands instead of decrypted ones
* some refactoring
* fix hf mf sim
* timing: decrease time to get ready for new reader commands
endless loop in reader if no tag was found
button press on pm3 did not cancel.
led_b was left on in some cases
also moved 14b detection to last in hf search to help speed up the
command for the other tags. 14b is slow (does multiple tests)
Thanks to @Fl0-0 and @pwpiwi for their idenfication of some of the
issues.
memory locations in code are now accurate and the CC output is not
corrupted by the config's crc.
also the looping and flags for what to read are now correctly
implemented in the code.
any memory from BigBuf[]. This is required because FpgaDownloadAndGo() might
allocate, use, and free most of BigBuf[] when decompressing FPGA configs.
- cleanup: remove rests of deprecated "end of trace markers" (0x44)
- provided a BigBuf_malloc() function to dynamically allocate parts of BigBuf
e.g. for DMA-Buffers, Frame-Buffers, Emulator-Memory
- the whole rest of BigBuf is now available for traces (instead of a small fixed amount)
- send actual traceLen together with trace data
- changed client side to cope with varying traceLen
- changed small buffers to automatic variables instead of parts of BigBuf
CHG: USB_CMD_DATA_SIZE is now used as maxsize for transfer of data between client and pm3device
CHG: suggested a fix for the underscore problem in ioclass\fileutils.c
ADD: tnp3xx support
ADD: nxp tag idents.
ADD: identifiction of chinese backdoor commands to hf 14a reader.
- buffers were too small to handle 256 byte frames
- parity bits were only handled for up to 32 byte frames
- trace format was inefficient
- removed parity calculation from decoders in iclass.c (parity not used on air anyway)
