/jtalg_rclk 0
I think is better
then If the board need to overwrite it the do it after the source of the soc
file
Best Regards,
please respect the 1/6 (Processor frequency / JTAG frequency) in case
the RTCK is not present, not featured by the device by the board or not
supported by the JTAG interface.
please use
jtag_rclk 5
in your case.
If the RTCK mechanism is supported by your device / your board / your
JTAG interface, the JTAG will start generating TCK edges at the maximum
frequency featured by the JTAG interface ( as 30MHZ for a Amontec
JTAGkey-2 ).
The frequency will be controlled by the target via the RTCK signal. So
no need to be worry about the frequency of the processor, regarding post
init reset procedure ...
