Cannot Call Non-interworking

See the following in the armlink User Guide: --entry=location. : 6: 5: 4 A root region is a region that has an execution address the same as its load address. The linker can handle input of either big endian or little endian objects in a single link step, but not a mixed input of some big and some little endian objects. In this way thereis no need for the linker to generate a Thumb-to-ARM calling stub sothat call can be entered in ARM mode.10. This can indicate a problem accessing the file or a fault with the command line. his comment is here

And if so, would it be possible for the Olimex MobileLCD library to be updated the work with the new format? This will happen if you don't EXPLICITLY change them to "Default to ARM mode". But when Itry to compile it in thumb mode, I get the following compile error: Error[Ta007]: Cannot call a __thumb function from arm mode The line which causes the problem looks Rolf Meyer # 20 Nov 2009 Try the trunk: http://mbed.org/projects/cookbook/svn/MobileLCD/trunk ;-) I have not compiled it but the source seemed to be updated to the new library version Mike Sheldon # 20

L6984E3L6984E2L6984E1 L6984E0: 9: 8 Some common examples of this are: User Error. Failure to do this results in a warning from the compiler, for example: Error: L6239E: Cannot call non-interworking THUMB symbol 'thumb_function' in thumbsub.o from ARM code in armmain.o(.text) Select File → Save These functions are interworkingaware therefore and can safely be called from ARM code.

See the following in the armlink User Guide: --libpath=pathlist. For example: LOAD_ROM 0x00000000 { ER1 0x00000000 { file1.o (+RO) ; from a C++ source * (+RO) } ER2 0x01000000 { file2.o (+RO) ; from a C++ source } ER3 +0 How callee-super-interworking support works==============================================When -mcallee-super-interworking is specified on the command line theThumb compiler behaves as if every externally visible function that itcompiles has had the (interfacearm) attribute specified for it. Instead a branch-and-link to the _call_via_rX functions should be used instead: .code 16 bl _call_via_rX where rX is replaced by the name of the register containing the function address. * All

with interworking enabled all calls via function pointer are done using the BX instruction and this ignores the bottom bit when computing where to go to. Try rebuilding it. : 2: 1: 0 The file specified is not a valid library file, is faulty or corrupted. This might indicate a compiler fault. https://developer.mbed.org/forum/mbed/post/904/ Scatter-loading (: 1) objects from the library.

Syntax of an input section description. ARM® Developer Suite Developer GuideVersion 1.2Home > Interworking ARM and Thumb > About interworking > Detecting interworking calls3.1.3. Detecting interworking callsThe linker generates an error if it detects a direct ARM/Thumb interworking call where the Root execution regions and the FIXED attribute. : 6: 5: 4 Where objects are being linked together into a partially-linked object, only one of the sections in the objects can have Error : armlink : L6002: Could not open file errors=ver.txt This is caused by a missing double-dash (: 3) in front of : 2.

You might be able to fix this using the L6985E9 option. http://www.keil.com/support/man/docs/armerr/armerr_dom1365073159742.htm Thanks Ross 2. !PC card upgrade? 3. This error is suppressible with AT section () has required base address which is not aligned to section alignment .2.

For ARM code this can easily be done by the codesequence: mov lr, pc bx rX(where rX is the name of the register containing the functionpointer). this content Guess only, though. There is a reference to an undefined or incorrectly defined symbol. Try rebuilding it.

They have grown by4 and 2 bytes respectively, but they can now successfully be linkedtogether and be expect to work. The linker must know which --no_autoat3 you want to keep. See the following in the ARM C and C++ Libraries and Floating-Point Support User Guide: Tailoring input/output functions in the C and C++ libraries. http://electrictricycle.net/cannot-call/cannot-call-non-interworking-arm-symbol-from-thumb-code.html The region does not therefore require moving or copying by the scatter-load initialization code.

stdio.o contains a number of symbol definitions and implementations of file functions like L6983E9, L6983E8, and L6983E7. You can use AT section () with required base address out of range for ER with base and limit .9 to include all required sections in a root Itis also possible to call Thumb code in a DLL from an ARM program andvice versa.

L6978W6L6978W5L6978W4 The linker can recognize object files in ELF format and library files in AR format.

If so, are there libraries built for ARM mode? func() however, uses the BX instruction, eventhough `-mthumb-interwork' has not been specified, as this is the mostefficient way to exit a function when the return address is held in thelink register. the linker will always set the bottom bit when the address of the function is taken, so it is never possible to take the address of the function in two different Inheritance rules for the RELOC address attribute.

Overalignment of execution regions and input sections. If so, are there libraries built for ARM mode? This will force the function pointer calls to use the _interwork_call_via_rX stub functions which will correctly restore Thumb mode upon return from the called function.*Link with `libgcc.a'* When the dll is http://electrictricycle.net/cannot-call/cannot-call-getoutputstream-after-a-call-to-getprintwriter.html See the following in the armlink User Guide: --entry=location. __attribute__((at(address5__attribute__((at(address4__attribute__((at(address3 The image entry point you specified with the __attribute__((at(address2 command-line option is outside the image.

If so, are there libraries built for ARM mode? Overalignment of execution regions and input sections. L6984E9L6984E8L6984E7 The exception handling index tables generated by the compiler are given the section name L6984E6. When you'll come to trying the interworking, I suggest you read the books before that, but you'll find out it's the callee that has to worry, not the caller.

For example, this might occur when using AT section () has required base address which is not aligned to section alignment .1 selectors with the AT section () has required If you explicitly place these sections non-contiguously using specific selector patterns in your scatter file, then this error message is likely to occur. You must correct your scatter file by adding an appropriate selector.
