FT2232 to Digilent JTag for Xilinx FPGAs (ISE/Vivado)

The Digilent JTag uses FT2232, but its configuration EEPROM contains secrete data needed to be recoginzed by Xilinx ISE/Vivado. The following method only works on linux (tested on Ubuntu16.04), but the patched FT2232 doggle also works on Windows. Since WSL1 does not provide USB device access, the following method will not work for WSL1.

DONT use FT_Prog on offical Digilent cable, as it can trash the firmware! The offical eeprom contains secrete data that cannot be handled correctly by FT_Prog.

Here are steps to create a Digilent-like Jtag that can be used in Xilinx ISE and Vivado

  1. Install softwares: sudo apt-get install libftdi1 ftdi-eeprom
  2. Create a file "flash_digilent.conf" with the following content:

Find out if your Wifi adapter supports monitor mode

Windows: netsh wlan show wirelesscapabilities in admin cmd shell, look for Network monitor mode.

Linux: iw list | grep -Fe "Supported interface modes" -n10, look for * monitor in section Supported interface modes:.

In Kali Linux

I boot a live Kali 2024.1 on a 8G USB stick on a Acer ES1-531-P8NJ and install hcxdumptool and hcxtools from the official repo. The version of hcxdumptool from the repo is 6.3.1 as of 20240420.

Stop Wifi related services

Boot Windows 10 and WinPE from PXE (IPXE)

Pre-requests:

  1. TFTP server
  2. IPXE Make sure ipxe.lkrn is in the TFTP root.
  3. iSCSI target (Server) Assume we have an iSCSI target "1:net.cszombie.au:windows" that is ready to be connected. 1 is LUN id, "net.cszombie.au:windows" is the target name.
  4. HTTP server (To speed up loading boot.wim, http is faster than tftp, http is supported by IPXE, however this is optional)

1. Download wimboot to the root of the TFTP server

2. Create scripts:

Install an OpenWrt KVM on a PVE host machine
  1. Install PVE using the official ISO and create a KVM with 512MB of ram and no disk.
  2. In the PVE host shell, run these commands to import the official OpenWrt image into the VM:
cd /tmp
wget https://downloads.openwrt.org/releases/23.05.2/targets/x86/64/openwrt-23.05.2-x86-64-generic-squashfs-combined-efi.img.gz
gunzip openwrt-23.05.2-x86-64-generic-squashfs-combined-efi.img.gz
# Replace 101 with the VM ID 
qm importdisk 101 openwrt-23.05.2-x86-64-generic-squashfs-combined-efi.img local-lvm
