-===== Update the System ==
+This also creates new jffs2.img and linux.flashme files in ''/tftpboot''
+Note that the manual states to call ''make menuconfig''. But in my case it changed noting in ''uclinux-dist'', so i think it is unnecessary.
+===== Set Date/Time on Target ==
+  - Set the date/time in **UTC** with ''%%date MMDDhhmm[[CC]YY]%%''.\\ (According to the manual 4.3.2 date sets the realtimeclock, but this is //not// true.)
+  - Save the system time to the hardware clock: ''hwclock --systohc''
+  - Afer a reboot a call to ''date'' should print the correct //local// time.
+===== Update the Target System ==
 Sources:
-  - [[http://www.wago.com/wagoweb/documentation/750/eng_dat/d086000e.pdf|Manual]]
+  - Manual
   - [[http://denx.de/wiki/DULG/Manual|DENX U-Boot and Linux Guide (DULG)]] -> 5.9. U-Boot Command Line Interface
 This guide is based on the manual -> 5.10 File System and Linux Kernel Update
-  - Boot, log in as root and set the date/time with ''%%date MMDDhhmm[[CC]YY]%%''. According to the manual 4.3.2 date is part of Busybox and sets the realtimeclock, so that the hwclock command is //not// necessary.
+  - Boot, log in as root and set the date/time (see above)
+  - Reboot and enter uboot ((see manual->5.10.2)); ''LFBK #'' appears
   - Type ''printenv'' to check the environment variables and correct the ipaddresses of the FBK and the server if required:<code>setenv ipaddr 192.168.xxx.yyy
 setenv serverip 192.168.xxx.zzz
@@ Zeile 59: / Zeile 74: @@
   - Compare all other variables with the actual manual and correct them if required. Especially check ''update-rootfs'', ''update-kernel'' & ''update-ub''. (E.g. ''printenv update-kernel'')
   - Type ''saveenv'' to save the modifications into the flash.
-  - Start TFTP with ''/tftpboot'' as TFTP source directory (uncomment and modify the line in ''/etc/inetd.conf'' accordingly; make ''/etc/rc.d/rc.inetd'' runnable and start it with ''/etc/rc.d/rc.inetd restart'')
+  - Start TFTP on your development machine with ''/tftpboot'' as TFTP source directory (uncomment and modify the line in ''/etc/inetd.conf'' accordingly; make ''/etc/rc.d/rc.inetd'' runnable and start it with ''/etc/rc.d/rc.inetd restart'')
   - Only necessary if "Compile all" (see above) hasn't been done: Mount the toolchain.iso and copy ''linux.flashme'' and ''jffs2.img'' to ''/tftpboot''
   - Update:<code>run update-kernel
 run update-rootfs</code>Dont use a managed Hub; if you encounter problems with your hub or switch, use a crosslink cable!
   - To see the boot messages and to get a login shell on the serial connection after the update to kernel 2.6 the little switch on the right side of the serial connector has to be set to the upper position!
+===== Apply Patches ==
+==== "soft lockup" Patch ==
+The FBK freezes with this message: ''BUG: soft lockup detected on CPU#0!''
+Download the patch from the [[http://www.wago.com/cps/rde/xchg/wago/style.xsl/deu-16260.htm|Wago service]] and apply the patch according to the help file. Afterwards you again have to [[#compile all]], [[#update the target system]] and configure the [[#webserver]].
+==== "RAM disk handling" Patch ==
+FIXME May affect Unix domain sockets!
 ===== Create a new App ==

 ==== What gets included? ==
 FIXME
-''$(CFLAGS)'' contains as the first ''-I''-switch the path ''$HOME/uClinux/lib/uClibc/include'', which points to ''$HOME/uClinux/uClibc/include''. Here are all common header files.
+''$(CFLAGS)'' :?:((Where is CFLAGS?)) contains as the first ''-I''-switch the path ''$HOME/uClinux/lib/uClibc/include'', which points to ''$HOME/uClinux/uClibc/include''. Here are all common header files.
 Auch ''asm/types.h'' wird hier gefunden, jedoch löst das der asm-Symlink tatsächlich nach ''~/uClinux/linux-2.4.x/include/asm/types.h'' auf.
+===== Webserver ==
+==== Mime Types ==
+The default Boa installation on the 750-860 serves CSS files with the mime type ''text/html'' instead of ''text/css''. This my lead to problems especially when HTML document type "strict" is used. Go around this by adding the line
+  AddType text/css css
+to ''/etc/boa/boa.conf''
+:!: Note: The path to the mime.types file in ''boa.conf'' is wrong: ''/etc/mime.types'' instead of ''/etc/boa/mime.types''. But even wiht the correct path, the mime.types file seems to be ignored.
+==== Logging ==
+:!: Error- and access logging does not work. If the according directive in ''boa.conf'' ist activated, eg ''ErrorLog'', the server refuses to start.
+===== Install cron ==
+Two cron apps are coming with wago uclinux-dist: cron and vixie-cron. cron ist smaller so I use this one.
+Add ''cron'' to the ''dir_y'' variable in ''~/uclinux-dist/user/Makfile'', compile and install it on the target.
+Example: The following 2 files are necessary to make the digital output 4.0 change its state every minute:
+<code bash>
+cat /etc/config/crontab
+#
+*  *  *  *  *  root  /bin/beckis
+</code>
+<code bash>
+cat /bin/beckis
+#!/bin/msh
+kbusdemo -n 4.0
+sleep 2
+kbusdemo -o 4.0
+</code>
+FIXME Start cron at PO. Where to add the cron start command? In ''/etc/startwago''? Lock at Manual!
