From d0be1630dc080b0c881830fa28bf2ccfe7850bb8 Mon Sep 17 00:00:00 2001 From: Rohit Singh Date: Fri, 12 Oct 2018 20:42:11 +0530 Subject: [PATCH] tcl: Add support for the Numato Lab Mimas A7 board The Mimas A7 FPGA board has FTDI FT2232 whose channel B is connected to Artix-7 FPGA's JTAG interface. Hence, OpenOCD can easily interface with it via the its ftdi driver interface. Tested to be working great up to 30 MHz.
