NOTE
Please, take into account that Olimex USB JTAG cable adapters after powering up
(just after their USB cable connecting) hold debug connector’s SRSTn line in
asserted state, actively holding entire processor subsystem in reset state. To release
SRSTn line, it is necessary to initialize cable adapter’s HW. That could be done, for
instance, by launching of OpenOCD configured for joint work with those cable
adapters.
