The uclibc startup code in FPC has never been adapted for EABI support. As mentioned earlier: it is not maintained. You can try copying the _haltproc_eabi from cprt0.as, but a) it may still not work b) it will still be unmaintained and unsupported until someone steps in to properly maintain it Jonas___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

Based on the extra information that you provided in your bug report at
http://bugs.freepascal.org/view.php?id=15860, it is clear that you are using an
RTL that is compiled for OABI. The reason is that gdb stops at
rtl/linux/arm/syscall.inc:187, and line 187 lies in the {$else} part of an
{$ifdef FPC_ABI_EABI}.
How did you compiled FPC?

AN IDE (Integrated Development Environment) does not need a display on the target device, it just offers improved comfort when editing, compiling, debugging the project. Lazarus and MSE consist both of an IDE and a component library that (among other stuff, that even might be useful for your goals, like "TNoGUIApplication" with MSE) offers components for creating a GUI on the target device (which of course is of no use for you). The IDE (both Lazarus and MSE) should offer remote debugging through GDB and thus could help a lot with embedded development like you (and I) are intending to do. -Michael ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

[fpc-devel] FPC on ARM, Debian "Lenny"
Using Debian "Etch", which is arm rather than armel, I was able to compile FPC 2.2.2 running natively on an ARM system. I was subsequently able to use this to compile Lazarus 0.9.27, hence generate X applications natively. I can't remember whether I did any debugging. Debian "Lenny" has switched to armel rather than arm. FPC 2.2.2 installs without error but trying to compile the canonical test.pas I get: /usr/bin/ld: ERROR: Source object /usr/local/lib/fpc/2.2.2/units/arm-linux/rtl/system.o has EABI version 0, but target test has EABI version 4 I think this is a fairly succinct indication of why I wasn't able to get FPC to compile itself prior to compiling Lazarus for Lenny. Looking at the Debian "Lenny" repository, there is an fpc metapackage but the components- fp-compiler etc.- are not available. From recent discussion I presume that to progress this I have to cross-compile, either on Debian "Etch" or on a non-ARM system. Can somebody point me at the information I need, and tell me explicitly what target I should be using? Is there any way I can help by packaging an armel build for download, ditto for v2.2.3 for SPARC? -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel

Point me to some description and I'll implement it. I searched the web for some details: http://www.state-machine.com/arm/Building_bare-metal_ARM_with_GNU.pdf shows the complete interrupt mess on Page 6-1ff regarding gcc. http://www.inf.ethz.ch/personal/wirth/Articles/Oberon/Interrupts.pdf Page 1 and 2. http://www.mikrocontroller.net/topic/71979 Last post from Martin Thomas. and did not look further. I really think it is not worth your effort to implement this in fpc now. ARM interrupt handling is so complex, because of the different ARM modes and the different exception types (IRQ/Fast IRQ/SWI etc. which need different return address alignment). Another point are the vendor specific vector controller implementations. I think this would be very hard to implement, hard to debug and maybe error prone. I could live with a performance penalty and think my second approach (going via the wrapper in the startup code) is perhaps the better start with fpc. This would have had the advantage too, that this should work with other controller vendors (ATMEL, ST, NXP, Samsung) without changing the compiler. Only the linker script and the startup code had to be adapted. Regards, Bernd. ___ fpc-devel maillist - fpc-devel@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-devel
