Programming

I am using an el cheapo USB to FT232H UART adapter from AliExpress

Pin connections

JTAG	FTDI
TCK	AD0
TDI	AD1
TDO	AD2
TMS	AD3
VCC	3.3V
GND	GND

Steps

First we need to change the frequency line in the SVF file... The default 1MHz is too fast, so we're slowing it to 300KHz which seems to work fine.

$ sed -i "s/FREQUENCY 1E6 HZ/FREQUENCY 3E5 HZ/" mitec2.svf

Second we need to setup UrJTAG for the CPLD, but adding the xc9536xl_vq44 stepping to the configuration (you may need to change this file path depending on your install)

$ echo "0101    xc9536xl_vq44   5" | sudo tee -a /usr/local/share/urjtag/xilinx/xc9536xl/STEPPINGS

Finally, we can program

$ sudo jtag

If all went well, you will get the success message
