| + | Es gibt aber Einschränkungen, siehe [[LPCTool#Lpctool-Probleme]]. | ||
| + | |||
| + | ==Linux== | ||
| + | === Debian Paket === | ||
| + | Für Debian Basierte Distr. kann man folgendes Paket nehmen. | ||
| + | <pre> | ||
| + | http://www.grautier.com/grautier/index.php?/plugin/dlfile_108 | ||
| + | </pre> | ||
| + | |||
| + | === selbst kompilieren === | ||
| + | Man benötigt die ARM-toolchain, siehe [[Entwicklungsumgebungen]] | ||
| + | |||
| + | Das LPCTool kann man unter Linux mit subversion herunterladen. | ||
| + | |||
| + | <pre> | ||
| + | svn co http://boopfirmware.svn.sourceforge.net/svnroot/boopfirmware/lpctool/ lpctool | ||
| + | </pre> | ||
| + | |||
| + | Alsdann kann das Programm compiliert werden: | ||
| + | |||
| + | <pre> | ||
| + | cd trunk | ||
| + | make | ||
| + | sudo make install | ||
| + | </pre> | ||
| + | Bei dem Paket für Debian Basierte Systeme | ||
| + | <pre> | ||
| + | dpkg -i LPCTool.deb | ||

| + | </pre> | ||
| + | |||
| + | Wenn man LPCTool installiert hat (Debian-Paket oder <code>make install</code>) lässt man das <code>./</code> weg. | ||

| + | ===Windows=== | ||
| + | Flashen kann man dann z.B. so: | ||
| + | |||
| + | <pre> | ||

| + | |||
| + | Falls nach dem Laden des Bootloaders (ramtool) die Fernbedienung neu startet (reset!) - | ||
| + | im Quellcode die Geschwindigkeit (u.a. TOOLBAUD) von 115.200 baud auf 38.400 baud | ||
| + | reduzieren. | ||
| + | "tcsetattr" toggelt beim Baud-Wechsel (38.400->115.200) den reset-Pin (Linux, CentOS 5, USB-Seriell-Kabel, Windows mit FT232R, Linux mit PL2303(H?)X. | ||
| + | |||
| + | Eine gebremste lpctool-cygwin für Windows gibt es [http://bettyhacks.com/forum/index.php?topic=54.msg842#msg842 im Forum]. | ||
| + | |||
| + | Eine mit cygwin für Windows gebaute Version, die ohne Baudratenwechsel bei 38400 baud auskommt gibt es ebenfalls [http://bettyhacks.com/forum/index.php?topic=241.msg1667#msg1667 im Forum]. Getestet mit PL-230? USB-UART Wandler. | ||
