Open source ARM Debugger

Hi,

On some jtag board schematics I see srst signal input is used in some jtag programmers, so ft2232 can "sense" if target board is being held in reset.

In interface config files i understand how nsrst signal is handled by using ftdi_layout_signal. But I am confused how "srst sense" signal is being handled.

Couldn't find information about this(maybe i couldnt find proper search keys for the topic).

Please help, thank you.

ok, i got a reply from an opensource jtag board developer. and he said , sense signal "can" be used by software but currently openocd doesn't use that.
