I am reviewing the STR710 evaluation board schematics and notice that the JTAG "nJTRST" signal will be asserted whenever the JTAG "nRESET" signal is also asserted. According to application note AN2099 (from ST MICRO), if these two signals are tied together, it will prevent any JTAG communication with the embedded ICE registers. Does anyone have any knowledge of this? Should these two signals be separated for proper JTAG operation? When SHOULD they be tied together? Thanks for any info.
