Hi Paul, nsrst_delay works, but regression for PSoC4 resists.
XRES (nSRST) resets also SWD DP so SWD line reset and DP reinit is needed. I'm not sure if reset_config srst_pulls_trst should address this - I do not see any change if srst_pulls_trst or separate is set. Anyway chg 2583 tries ahbap_debugport_init() and fails without ftdi_swd_switch_seq() On the other hand git master discovers not communicating swd in poll and resolves the problem correctly.
