Also, as already discussed with Spencer, it would be nice to deprecate jtag/hla/swd/cmsis-dap new[dt]ap commands and instead introduce \"transport newtap\" (and probably an equivalent alias \"transport newdap\") so that transport layer would pass the arguments to the current transport automatically.","accounts_in_message":[],"_revision_number":2},{"id":"62548d6587d2a7389bddff639716bf540764c346","author":{"_account_id":1000160,"name":"Paul Fertser","email":"fercerpav@gmail.com","username":"pfertser"},"real_author":{"_account_id":1000160,"name":"Paul Fertser","email":"fercerpav@gmail.com","username":"pfertser"},"date":"2014-02-22 17:32:15.000000000","message":"Patch Set 2:\n\nTo sum up, afaict:\n\nOlimex, Rowley: TRST low enables SWD, TMS low gates TDI -\u003e SWDIO;\nKT-Link: ADBUS5 low enables SWD, ACBUS4 low gates TDI;\nJTAG-lock-pick Tiny 2: ADBUS5 low enables SWD, ACBUS4 high gates TDI (Freddie, did I get it right?
