Mac M1 (Apple Silicon)

Using a Mac with Apple Silicon

• Using Parallel to create a Windows 11 for ARM VM
• Installed Vivado
• Windows is missing the FTDI drivers - install Adapt from Digilent will add the missing drivers
• Use Windows 11 Arm version to generate bitstream
  • With the drivers Vivado can configure and Putty can listen to the serial port
• Configure from Mac with open OCD
  • see https://github.com/byu-cpe/BYU-Computing-Tutorials/wiki/Program-7-Series-FPGA-from-a-Mac-or-Linux-Without-Xilinx
    • Run it as sudo
  • Configuration (several A7 boards, e.g., Basys3, NexysA7) is in 7series.txt:

# File: 7series.txt
interface ftdi
ftdi_device_desc "Digilent USB Device"
ftdi_vid_pid 0x0403 0x6010
# channel 1 does not have any functionality
ftdi_channel 0
# just TCK TDI TDO TMS, no reset
ftdi_layout_init 0x0088 0x008b
reset_config none
adapter_khz 10000

source [find cpld/xilinx-xc7.cfg]
source [find cpld/jtagspi.cfg]
init

puts [irscan xc7.tap 0x09]
puts [drscan xc7.tap 32 0]  

puts "Programming FPGA..."
pld load 0 Hello.bit
exit

• Get the .bit file (from the Windows machine) and set the name in the 7series.txt
• Configure with: openocd -f 7series.txt
• On the Mac: ls -l /dev/cu.*
• Serial port: screen /dev/cu.usbserial-.... 115200
