Microblaze Toolchain

Für den Aufbau eines vollständig geschlossenen Design Flow ist neben MB-Ref auch eine funktionstüchtige Toolchain der GNU Compiler Collection für das Linux Zielsystem notwendig. Mit Stand Q1/2012 gibt es für dieses Zielsystem noch keine ordentliche Unterstützung durch die aktuellen Up-Stream Versionen der FSF (mehr dazu).

Mit der Veröffentlichung der Patches für die GNU Binutils, den GCC und die GLIBC auf http://git.monstr.eu/git/gitweb.cgi besteht nun erstmalig die Möglichkeit, eine eigene Microblaze GNU Toolchain zu erzeugen. — Stephan Linz 2011/11/03 20:02

Wie sich in einem kurzen Gespräch mit John Williams im Februar 2012 auf der Embedded World in Nürnberg herausstellte, wird PetaLogix noch im Frühjahr 2012 eine komplett überarbeitet Toolchain auf Basis der eGLIBC veröffentlichen. Diese soll dann auch Up-Stream zur FSF gehen. — Stephan Linz 2012/04/17 20:51

Am 16. August ist nun im Spätsommer 2012 eine erste frei verfügbare Toolchain neueren Datums im Git Repository von Xilinx erschienen (http://git.xilinx.com/?p=microblaze-gnu.git). Die Verspätung ist wohl neben der Integration in eine der kommenden ISE/EDK Version 14 auch dem Umstand geschuldet, dass John Williams Firma, PetaLogix, nun ein Teil von Xilinx geworden ist. Die aktuelle Toolchain basiert auf dem GCC 4.6.2 und der eGLIBC 2.14.90 sowie dem GDB in Version 7.4.50.20120403-cvs. — Stephan Linz 2012/09/28 21:03

Nun ist ein Jahr vergangen und ich habe mir Zeit genommen, die Veröffentlichungen von Xilinx zu Nutzen und wieder eine eigene Toolchain auf Basis von Crosstool-NG zu erstellen. Bis auf den GDB, der ungetestet in Version 7.4.50.20120403-cvs verblieben ist, basiert die aktuelle Toolchain nun auf den Binutils 2.23.2 dem GCC 4.8.1 und der eGLIBC 2.18. Genutzt wurden die Linux Kernel Header aus Version 3.8.11 aus PetaLinux v2013.10. — Stephan Linz 2013/12/22 17:28

Mit Hilfe von Crosstool-NG (Mainline HEAD) und ein paar zusätzlichen Erweiterungen können die bereitgestellten Erweiterungen von Xilinx an den GNU Tools und der Glibc (Original von http://git.xilinx.com/) für die Erzeugung einer eigenen Toolchain genutzt werden. Eine Anleitung befindet sich weiter unten. Für diese selbst erstellte Toolchain gilt: ohne Garantie, ohne Haftung für etwaiger Schäden und ohne Unterstützung jedweder Art.

Achtung: Die aktuelle Ausgabe v2.4 kann nur auf Systemen mit glibc-2.11 oder höher benutzt werden und beinhaltet den ungeprüften Debugger gdb-7.4.50.20120403-cvs, da es bisher noch keine stabile Veröffentlichungen der notwendigen Patches durch Xilinx gibt.

MicroBlaze Tools v1.4 (crosstool-1.4.1)

Die Microblaze Toolchain wird durch Xilinx und PetaLogix aufbereitet und ohne Garantie, ohne Haftung für etwaiger Schäden und ohne Unterstützung jedweder Art bereitgestellt. Sie befinden sich in einem finalen Stadium und darf bei Akzeptanz der benannten Bedingungen produktiv eingesetzt werden.

Die aktuelle Ausgabe ist: v3.0

Die aktuelle PTXdist Kennung für Big Endian ist: Xilinx MicroBlaze Tools v3.0 (14.3_early.20120816)

Die aktuelle PTXdist Kennung für Little Endian ist: Xilinx MicroBlaze (LE) Tools v3.0 (14.3_early.20120816)

Achtung: Die aktuelle Ausgabe v3.0 kann sowohl auf 32-bit als auch auf 64-bit Systemen mit glibc-2.3 oder höher benutzt werden und beinhaltet wieder einen Debugger (gdb auf Kommandozeile). Diese Ausgabe sollte wieder unter älteren Systemen nutzbar sein.

Anmerkung zu v2.0: Die Ausgabe v2.0 kann nur auf 64-bit Systemen mit glibc-2.11 oder höher benutzt werden und beinhaltet keinen Debugger (gdb/Insight). Für ältere Systeme oder bei der Notwendigkeit eines funktionstüchtigen Debugger kann nur die Version v1.0 genutzt werden.

Crosstoll-NG ist ein bekanntes Werkzeug zur Übersetzung von GNU Toolchains für verschiedene Prozessoren wie ARM, PowerPC, MIPS, x86 und viele mehr. Die Nutzung für Microblaze ist nicht neu wurde aber bisher nur zum Teil als offizielle Unterstützung eingepflegt. Nachdem PetaLogix seit Februar 2011 und Xilinx seit Ende 2012 alle notwendigen Patches für die GNU Binutils, den GCC und die (e)GLIBC veröffentlichen, habe ich für meine Arbeiten eine eigenen Konfigurationsumgebung für Microbalze erstellt und auf Gitorious als Git Repository veröffentlicht.

Die Übersetzung erfolgt in mehreren einzelnen Schritten, wobei zunächst Grosstool-NG für die lokale Benutzung vorbereitet werden muss, dann die drei Toolchains für Big und Little Endian übersetzt und abschließend die Ergebnisse eingepackt werden. Im Verlauf der Übersetzung einer GNU Toolchain müssen verschiedene Zwischenergebnisse bereits in eine gültige Laufzeitumgebung installiert werden. Die in Crosstoll-NG hinterlegten Konfigurationen für die drei Microblaze Toolchains sind so eingestellt, dass diese Installationen unterhalb von /tmp erfolgen. Somit ist auf ausreichend Plattenplatz in diesem Bereich zu achten (ca. 2,5GB). Je nach Leistungsfähigkeit der benutzen Maschine können Übersetzungszeiten von mehr als einer Stunde erwartet werden. Ein gutes Buch, viel Kaffee oder auch ein nicht aufgeräumtes Büro werden da sehr nützlich.

3. Übersetzungsumgebung aufräumen:

   user@host: ./ct-ng distclean

     CLEAN scripts
     CLEAN config
     CLEAN config.gen
     CLEAN log
     CLEAN .config
     CLEAN build dir

1. Crosstool-NG hat beide Toolchains unter /tmp/tools-4.8.1-mb-ctng-v2.4 installiert, diese müssen eingepackt werden:

   user@host: cd /tmp
   user@host: tar -cj --owner=root --group=root -f tools-4.8.1-mb-ctng-v2.4-$(uname -m).tar.bz2 tools-4.8.1-mb-ctng-v2.4

2. Das entstandene Archiv muss nun an einen sicheren Ort verschoben werden, dann kann das Verzeichnis gelöscht werden:

   user@host: mv tools-4.8.1-mb-ctng-v2.4-$(uname -m).tar.bz2 <safe_location>
   user@host: rm -rf tools-4.8.1-mb-ctng-v2.4

3. Die Toolchains können für die Benutzung nach /opt installiert werden:

   user@host: cd /opt
   user@host: sudo tar -xjf <safe_location>/tools-4.8.1-mb-ctng-v2.4-$(uname -m).tar.bz2
