nSRST and sysreqreset are both broken for these targets. Upon a hard reset, the target disables the TDO/TDI pins and the ICEPick router will remove the target's TAP from the scan chain. The scripts to do these tasks are run, but then OpenOCD throws the reset again breaking the debug connection. Until that issue can be resolved, vectreset is the only reset that works without breaking the debug connection. Update: original patch didn't have the correct reset command.
