+I still have some important hints to you regarding this.
+
+minsoc_top.v: on line 817 you should also include:
+assign wb_gpio_err_o = 1'b0; (otherwise simulation might drive crazy and prob real life if it doesn't "automatically" be set to 0.
+
+You probably missed it since these are gathered together around line 358 for uart, spi and start_up. And I forgot myself to add it for Ethernet.
+
+On gpio_defines.v, the GPIO_IOS definition I'd set directly to 32. Instantiation would be instead of GPIO_IOS + 1, GPIO_IOS only. Is there any problem regarding this? The definitions generally are more human friendly than coding, so the register definitions of reg [GPIOS_IOS-1:0] which considers 0 to be something is let for the implementation. That's more or less standard I'd say. It is the same as when you define the address width on minsoc_defines.v you define it and I implement it considering the necessary -1s.
+
+GPIO_LINES32 instead of GPIO_LINES31.
+
+I'd substitute the whole minsoc_spartan_3a_starter_kit_ios.v. Instead of it, place a bidirectional port on minsoc_top if GPIO is enabled.
+`ifdef GPIO
+, gpio_io
+`endif
+
+//
+// GPIO
+//
+inout [GPIO_IOS-1:0] gpio_io;
+
+//
+// GPIO tri-state
+//
+// I hope this works without generate, otherwise it is also easy but I'd first try this way
+integer iterate;
+for (iterate = 0; iterate < GPIO_IOS; iterate = iterate + 1)
+ assign gpio_io[iterate] = ext_pad_oe_o[iterate] ? ext_pad_o[iterate] : 1'bZ;
+
+assign ext_pad_i = gpio_io;
+
+And then only define the pins for the inout port on the ucf file. Like this:
+NET "gpio_io(31)" LOC = "a1(pin number)" | DRIVE = 12 | SLEW = SLOW;
+NET "gpio_io(30)" LOC = "a1(pin number)" | DRIVE = 12 | SLEW = SLOW;
+...
+NET "gpio_io(0)" LOC = "a1(pin number)" | DRIVE = 12 | SLEW = SLOW;
+
+After that you only need the definition GPIO on minsoc_defines.v. Of course, interrupt and address you also still need.

+ using bin2hex.c file, provided with the ORPSoC v2 project. bin2hex executable must exist in the same folder with this script.
+
+ Currently init file is generated for Xilinx's RAMB16_S9 BRAMs

+//// This block is a wrapper with common single-port ////
+//// synchronous memory interface for different ////
+//// types of ASIC and FPGA RAMs. Beside universal memory ////
+//// interface it also provides behavioral model of generic ////
+//// single-port synchronous RAM. ////
+//// It should be used in all OPENCORES designs that want to be ////
+//// portable accross different target technologies and ////
+//// independent of target memory. ////
+//// ////
+//// Supported ASIC RAMs are: ////
+//// - Artisan Single-Port Sync RAM ////
+//// - Avant! Two-Port Sync RAM (*) ////
+//// - Virage Single-Port Sync RAM ////
+//// - Virtual Silicon Single-Port Sync RAM ////
+//// ////
+//// Supported FPGA RAMs are: ////
+//// - Xilinx Virtex RAMB16 ////
+//// - Xilinx Virtex RAMB4 ////

+// Changed some signal names for better consistency between different hardware modules.
+//
+// Revision 1.2 2009/05/17 20:54:16 Nathan
+// Changed email address to opencores.org
+//
+// Revision 1.1 2008/07/18 20:07:32 Nathan
+// Changed the directory structure to match existing projects.

+// Revision 1.4 2008/07/11 08:26:10 Nathan
+// Ran through dos2unix
+//
+// Revision 1.3 2008/07/11 08:25:52 Nathan
+// Added logic to provide CAPTURE_DR signal when necessary, and to provide a TCK while UPDATE_DR is asserted. Note that there is no TCK event between SHIFT_DR and UPDATE_DR, and no TCK event between UPDATE_DR and the next CAPTURE_DR; the Xilinx BSCAN devices do not provide it. Tested successfully with the adv_dbg_if on Virtex-4.

+Welcome to MinSoC.
+
+In order to put the system up and running, you should first visit MinSoC's Wiki
+that can be found at (http://www.minsoc.com). There, you will find guidance
+to retrieve and install the required tools, simulate and synthesize the design,
+and to run and debug the first firmware on your FPGA.
+
+IMPORTANT: By any arisen problems, doubts or special requirements, take a look
+into the FAQ pages (also in this very Wiki). It includes possible adaptations
+you can easily make to the system, solutions for the most reported problems
+using MinSoC and the Advanced Debug System, and even some tweak possibilities.
+If you have a problem which is not described there or you cannot make it work,
+please send us an email to .
+
+FINALLY: My system is up and running, what do I do next? The real system
+documentation is the minsoc.pdf document. It gives a thorough insight into
+MinSoC, its goals, design and ideas. It helps you to better understand the
+system and can give you a good idea of what to do next, after your system is up
+and running.
+
+Enjoy your time,
+Raul Fajardo

+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc.
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+ This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+ 0. Additional Definitions.
+
+ As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+ "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+ An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+ A "Combined Work" is a work produced by combining or linking an
+Application with the Library. The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+ The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+ The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+ 1. Exception to Section 3 of the GNU GPL.
+
+ You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+ 2. Conveying Modified Versions.
+
+ If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+ a) under this License, provided that you make a good faith effort to
+ ensure that, in the event an Application does not supply the
+ function or data, the facility still operates, and performs
+ whatever part of its purpose remains meaningful, or
+
+ b) under the GNU GPL, with none of the additional permissions of
+ this License applicable to that copy.
+
+ 3. Object Code Incorporating Material from Library Header Files.
+
+ The object code form of an Application may incorporate material from
+a header file that is part of the Library. You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+ a) Give prominent notice with each copy of the object code that the
+ Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the object code with a copy of the GNU GPL and this license
+ document.
+
+ 4. Combined Works.
+
+ You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+ a) Give prominent notice with each copy of the Combined Work that
+ the Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
+ document.
+
+ c) For a Combined Work that displays copyright notices during
+ execution, include the copyright notice for the Library among
+ these notices, as well as a reference directing the user to the
+ copies of the GNU GPL and this license document.
+
+ d) Do one of the following:
+
+ 0) Convey the Minimal Corresponding Source under the terms of this
+ License, and the Corresponding Application Code in a form
+ suitable for, and under terms that permit, the user to
+ recombine or relink the Application with a modified version of
+ the Linked Version to produce a modified Combined Work, in the
+ manner specified by section 6 of the GNU GPL for conveying
+ Corresponding Source.
+
+ 1) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (a) uses at run time
+ a copy of the Library already present on the user's computer
+ system, and (b) will operate properly with a modified version
+ of the Library that is interface-compatible with the Linked
+ Version.
+
+ e) Provide Installation Information, but only if you would otherwise
+ be required to provide such information under section 6 of the
+ GNU GPL, and only to the extent that such information is
+ necessary to install and execute a modified version of the
+ Combined Work produced by recombining or relinking the
+ Application with a modified version of the Linked Version. (If
+ you use option 4d0, the Installation Information must accompany
+ the Minimal Corresponding Source and Corresponding Application
+ Code. If you use option 4d1, you must provide the Installation
+ Information in the manner specified by section 6 of the GNU GPL
+ for conveying Corresponding Source.)
+
+ 5. Combined Libraries.
+
+ You may place library facilities that are a work based on the
+Library side by side in a single library together with other library
+facilities that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+ a) Accompany the combined library with a copy of the same work based
+ on the Library, uncombined with any other library facilities,
+ conveyed under the terms of this License.
+
+ b) Give prominent notice with the combined library that part of it
+ is a work based on the Library, and explaining where to find the
+ accompanying uncombined form of the same work.
+
+ 6. Revised Versions of the GNU Lesser General Public License.
+
+ The Free Software Foundation may publish revised and/or new versions
+of the GNU Lesser General Public License from time to time. Such new
+versions will be similar in spirit to the present version, but may
+differ in detail to address new problems or concerns.
+
+ Each version is given a distinguishing version number. If the
+Library as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+ If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.
