+                   GNU LESSER GENERAL PUBLIC LICENSE
+                       Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ 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

-# Build
+# Bare-metal Rust on Zynq-7000
+
+Supported features:
+
+* Clocking setup
+* UART
+* SDRAM setup
+* Ethernet with smoltcp and async-await on TCP sockets
+* SD card
+* PL programming and startup
+* Pure Rust SZL first-stage bootloader, with SD boot and netboot
+* Control of second CPU core and message passing, with async-await support
+
+
+Supported boards:
+ * Kasli-SoC
+ * ZC706
+ * Red Pitaya
+ * Cora Z7-10 (seems to also run on Cora Z7-07S, including dual-core support)
+
+## Build
+
+Zynq-rs is packaged using the [Nix](https://nixos.org) Flakes system. Install Nix 2.4+ and enable flakes by adding ``experimental-features = nix-command flakes`` to ``nix.conf`` (e.g. ``~/.config/nix/nix.conf``). 
+
+You can build SZL or experiments crate for the platform of your choice by using ``nix build`` command, e.g.

 ```shell
-nix-shell --command "cargo xbuild --release -p experiments"
+nix build .#coraz7-experiments
 ```

-Currently the ELF output is placed at `target/armv7-none-eabihf/release/experiments`
+Alternatively, you can still use ``cargo xbuild`` within ``nix develop`` shell.

-# Debug
-
-## Using the Xilinx toolchain
-
-Tested with the ZC706 board.
-
-Run the Xilinx Microprocessor Debugger:
 ```shell
-/opt/Xilinx/14.7/ISE_DS/EDK/bin/lin64/xmd
+nix develop
+cargo xbuild --release -p experiments
 ```

-Connect to target (given it is connected and you have permissions):
-```tcl
-connect arm hw
-```
+Currently the ELF output is placed at `target/armv7-none-eabihf/release/experiments`, or `result/experiments.elf` for Nix Flakes build.

-Leave xmd running.
-
-Start the Xilinx version of the GNU debugger with your latest build:
-```shell
-/opt/Xilinx/14.7/ISE_DS/EDK/gnu/arm/lin/bin/arm-xilinx-linux-gnueabi-gdb zc706
-```
-
-Connect the debugger to xmd over TCP on localhost:
-```gdb
-target remote :1234
-```
-
-Proceed using gdb with `load`, `c`
-
-## Using OpenOCD
+## Debug

 ### Running on the ZC706

 ```shell
-nix-shell --command "cargo xbuild --release -p experiments"
+nix develop
+cargo xbuild --release -p experiments
 cd openocd
 openocd -f zc706.cfg
 ```

 ### Running on the Cora Z7-10

 ```shell
-nix-shell --command "cd experiments && cargo xbuild --release --no-default-features --features=target_cora_z7_10"
+nix develop
+cargo xbuild --release -p experiments --no-default-features --features=target_coraz7

 ```
@ -60,43 +63,7 @@ openocd -f cora-z7-10.cfg
 openocd -f zc706.cfg -c "pld load 0 blinker_migen.bit; exit"
 ```

-### Development Process
-
-Clone this repo onto your development/build machine and the raspberry pi that controls the Xilinx 7000 board
-
-On the dev machine, the below script builds zc706 and secure copies it to the target pi (in your pi $HOME directory):
-```shell
-cd ~/zynq-rs
-./build.sh $your_user_or_ssh_id
-```
-
-On the pi, we need an information rich environment that includes a relatively reliable `gdb` experience (that includes `ctrl-p` and `ctrl-n` command history that persists across `cgdb` executions), run:
-```shell
-ssh pi4
-cd zynq-rs
-# For ZC706, run:
-./tmux.sh 0
-# For Cora Z7, run:
-./tmux.sh
-```
-
-Time to run your code with:
-```shell
-zynq-connect
-zynq-restart
-c
-```
-or, for a more succinct experience, (identical to above)
-```shell
-dc
-dr
-c
-```
-
-After every build on your dev machine, simply run:
-```shell
-dr
-c
-```
-Sometimes you might need to type `load` after `dr`.

+        The Clang project provides a language front-end and tooling
+        infrastructure for languages in the C language family (C, C++, Objective
+        C/C++, OpenCL, CUDA, and RenderScript) for the LLVM project.
+        It aims to deliver amazingly fast compiles, extremely useful error and
+        warning messages and to provide a platform for building great source
+        level tools. The Clang Static Analyzer and clang-tidy are tools that
+        automatically find bugs in your code, and are great examples of the sort
+        of tools that can be built using the Clang frontend as a library to
+        parse C/C++ code.

+      The LLVM Project is a collection of modular and reusable compiler and
+      toolchain technologies. Despite its name, LLVM has little to do with
+      traditional virtual machines. The name "LLVM" itself is not an acronym; it
+      is the full name of the project.
+      LLVM began as a research project at the University of Illinois, with the
+      goal of providing a modern, SSA-based compilation strategy capable of
+      supporting both static and dynamic compilation of arbitrary programming
+      languages. Since then, LLVM has grown to be an umbrella project consisting
+      of a number of subprojects, many of which are being used in production by
+      a wide variety of commercial and open source projects as well as being
+      widely used in academic research. Code in the LLVM project is licensed
+      under the "Apache 2.0 License with LLVM exceptions".

+On musl libc the fopen64 and fopen are the same thing, but for

+Subject: [PATCH] cmake: Enable 64bit off_t on 32bit glibc systems
+
+Pass -D_FILE_OFFSET_BITS=64 to compiler flags on 32bit glibc based
+systems. This will make sure that 64bit versions of LFS functions are
+used e.g. seek will behave same as lseek64. Also revert [1] partially
+because this added a cmake test to detect lseek64 but then forgot to
+pass the needed macro to actual compile, this test was incomplete too
+since libc implementations like musl has 64bit off_t by default on 32bit
+systems and does not bundle[2] -D_LARGEFILE64_SOURCE under -D_GNU_SOURCE
+like glibc, which means the compile now fails on musl because the cmake
+check passes but we do not have _LARGEFILE64_SOURCE defined. Using the
+*64 function was transitional anyways so use -D_FILE_OFFSET_BITS=64
+instead
