This application note provides information on how to modify the evaluation board for SPEAr310 (EVALSPEAr310) rev 2.0 to enable remote system reset through the JTAG interface.
The document describes a modification process for the EVALSPEAr310 evaluation board (rev 2.0) to allow remote system resets through the JTAG connector, which is not available by default on this revision.
To achieve this, users must perform specific hardware changes including mounting a new resistor (R329), removing and shorting pins of component U12, replacing reset chip U11 with STM6315SDW13F, and removing several delay circuit components to ensure JTAG compliance.
You need one device P/N STM6315SDW13F and one resistor in package 0603 with a value of 0 ohm.
The reset chip U11 must be replaced with a STM6315SDW13F.
Without modification, remote reset is not available by default on EVALSPEAr310 rev 2.0.
