Hi, I tried to convert the demo project "ARM7_LPC2129_Keil", and it seems there is something wrong with the portmacro.h, it can’t be compiled… here is the compilation error messages: Build target ‘LPC2888’ assembling Startup.s… compiling main.c… ..\..Sourceinclude\..\..SourceportableKeilARM7portmacro.h(112): error:  #52: expected a macro parameter name portmacro.h line 112:     __asm{ LDR        LR, [LR, #+60]    }; /* Restore the return address. */ And here is the IDE-Version of my Keil UV3     IDE-Version:     µVision3 V3.50     Copyright (c) Keil Elektronik GmbH / Keil Software, Inc. 1995 – 2007     Tool Version Numbers:     Toolchain Path:    C:KeilARMBIN30     C Compiler:         ARMCC.Exe       V3.0.0.951     Assembler:          ARMASM.Exe       V3.0.0.951     Linker/Locator:     ARMLINK.Exe       V3.0.0.951     Librarian:          ARMAR.Exe       V3.0.0.951     Hex Converter:      FROMELF.Exe       V3.0.0.951     CPU DLL:            SARM.DLL       V3.04     Dialog DLL:         DARMP.DLL       V1.13     Target DLL:         BINUL2ARM.DLL       V1.26     Dialog DLL:         TARMP.DLL       V1.11f My question is, are we using different compiler? because it seems that those errors is shown because of the compiler is treating the code differently? and indeed, when I tried to compile using the original project file (rtosdemo_ARM.Uv2), it said about cannot find the compiler. What should I do to compile these project files? Thanks in advance, Regards, Widita

If you are using FreeRTOS.org V5.1.0 then the project is setup to use the Keil/RVDS compiler.  If you are using a previous version then the project is setup to use the old and now obsolete Keil/Keil compiler. Regards.

Oh, I am not aware that v5.10 has been released, I will port my project right away and keep you updated. Thanks
