Revision 839 osimage has broken hf 14a snoop #52

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?
1. Flash to r839 firmware
2. Run 'hf 14a snoop'
3. Get "#db# COMMAND FINISHED" instantly

4. Flash r838 osimage
5. Run 'hf 14a snoop'
6. Works as expected

Please provide any additional information below.

Seems like the problem is the updated ManchesterDecoding function 
(armsrc/iso14443a.c). Demod.len blows the circular buffer immediately @ line 
677.
(please verify, that's almost pure guessing)

Fixed in r845, then additional fixes in r846.
