Hi,

 

There is a question about JTAG circuit of MCIMX6Q-SDB.

 

Follows are nSRST specifications.

  nSRST(Input/output)

     Active Low output from RealView ICE to the target system reset, with a 4.7kΩ pull-up resistor for de-asserted state.

     This is also an input to RealView ICE so that a reset initiated on the target can be reported to the debugger.

     This pin must be pulled HIGH on the target to avoid unintentional resets when there is no connection.

 

However, in MCIMX6Q-SDB, it does not support the following specifications.

    ・This is also an input to RealView ICE so that a reset initiated on the target can be reported to the debugger.
