Finally i done, i can run graphical binaries in a Tablet PengPod 1.2ghz Cortex A8 ARM Core.
The hardware:
www.androidpit.com/pengpod-the-true-linux-tabletthe result is awesome, literally is flying:
1.- in fact in can comunication with serial port reseeving data at 38400 bps, without problems, using spdo
2.- i can graphs in real time
3.- i can use mysql connection without problems
pd: the only problem, is you need to set up fontsize to 0 (label, button's, panels), otherwise dissapears
let'me advices to other people that the wiki tutorial 'CRoss-compile for ARM', wasn't work, only work if you want simple text application's, and why don't work?, i ' m not cross compile expert , but don't work because:
BEFORE you have FPC working
1.-Is necessary rebuild gcc
2.-Is necessary rebuild gdb
3.- Is necesary Newlib (rebuild too)
4.- rebuild binutils
5.- you need import lib's from the tablet, (/lib/ & /usr/lib/), in a directory on the host like 'licross125'
6.- you need to change some file names like: pango-1.2.so.000.1 -> pango-1.2.so (the compiler tell you the names)
the used parameter is differnet too, is=arm-elf
thank's to a german wiki tutorial, i can create the correct ToolChain:
the tutorial is:
(you need fpc running good before)
http://wiki.ubuntuusers.de/GNU_ARM-Toolchainand then follow this steps:
""After all it creates a structure in /opt/gnuarm which can be used to compile Hello-World. I was missing at least libgl and did not find a way to build it. So one can access different precompiled toolchains as well (
www.gnuarm.com/,
www.yagarto.de/,
www.codesourcery.com/). I downloaded this file decompressed it to /opt (arm-2009q3) and applied that path to all further steps.
5. fpc
make distclean
make crosszipinstall CPU_TARGET=arm OS_TARGET=linux OPT="-dFPC_ARMEL" CROSSOPT="-XR/opt/arm-2009q3/arm-none-linux-gnueabi -dFPC_ARMEL -CfSOFT -Cparmv5" FPC=/usr/local/lib/fpc/2.5.1/ppcx64
- crosszipinstall to create but not install
- -XR<> root dir where as and ld can be found
- ppcx64 is the compiler on 64bit systems, for 32bit it is called ppc386
It results in a packed file like fpc-2.5.1.arm-linux.tar.gz just where the makefile resides. Unpack the content to /usr/local/lib/fpc... and create a link for ppcrossarm into /usr/local/bin. Now ppcrossarm can be used to compile sources
6. Compilation
ppcrossarm -Xd -Fl/opt/arm-2009q3/arm-none-linux-gnueabi/libc/usr/lib -CaEABI -Parm -CfSOFT -CpARMV5 Example.pas
-Xd don't use standard lib path
-Fl use directory to search for libs
I don't know if it works without -C options.
"
and that's if, the full process, creates a nice 'ppcrossarm' and really works!
(don't forget the target libraries)
