The parport interfaces do not support jtag_khz or jtag_rclk commands. You have to use the undocumented jtag_speed command. jtag_speed takes a interface specific value as a parameter. For the parport interface it sets the number of dummy parallel port writes that shall be performed for each transition of the JTAG signals. The parallel port write delay differ between computers, but it should be close to 1 us. I measured it to be 1.37us for my PC. Two examples for a 1 us write time: # Max speed: 2 * (1us + 0us) = 2us -> 500kHz jtag_speed 0 # 10kHz -> 100us = 2 * (1us + 49us) jtag_speed 49 > > # Logs using debug_level 3 > logfile >
