You have to run "fpcmake -Tall" after modifying makefile.fpc to regenerate the makefile (and make sure you are using an fpcmake from FPC 2.5.1).

You need to modify the makefile to generate either a thumb2 rtl or a arm rtl. You can do that by removing the arm core units from CPU_UNITS

Yes, change Makefile.fpc so instead of: "ifeq ($(ARCH),arm) CPU_UNITS=lpc21x4 at91sam7x256 endif" it says: "ifeq ($(ARCH),arm) CPU_UNITS=stm32f103 endif" Then run fpcmake -Tall in the rtl/embedded dir Then you can build the compiler and rtl again using "make buildbase CPU_TARGET=arm OS_TARGET=embedded CROSSINSTALL=1 CROSSOPT="- Cpcortexm3 -O-"" Geoffrey Barton skrev: >> >> Date: Mon, 19 Apr 2010 15:06:23 +0200 >> From: Jeppe Johansen >> Subject: Re: [fpc-devel] arm embedded >> To: FPC developers' list >> Message-ID: >> Content-Type: text/plain; charset=ISO-8859-1; format=flowed >> >> 1) >> stm32f103 is a thumb2 only device, and you cannot generate a rtl for >> both <=armv5 and thumb2.

Thanks, I would never have guessed the CROSSOPT in quotes. I can now see thumb2 code in the object file. Next step try it with hardware :-) Geoffrey On 21 Apr 2010, at 10:18, Jeppe Johansen wrote: > Yes, change Makefile.fpc so instead of: > "ifeq ($(ARCH),arm) > CPU_UNITS=lpc21x4 at91sam7x256 > endif" > > it says: > "ifeq ($(ARCH),arm) > CPU_UNITS=stm32f103 > endif" > > Then run fpcmake -Tall in the rtl/embedded dir > > Then you can build the compiler and rtl again using "make buildbase > CPU_TARGET=arm OS_TARGET=embedded CROSSINSTALL=1 > CROSSOPT="-Cpcortexm3 -O-"" > > Geoffrey Barton skrev: >>> >>> Date: Mon, 19 Apr 2010 15:06:23 +0200 >>> From: Jeppe Johansen >>> Subject: Re: [fpc-devel] arm embedded >>> To: FPC developers' list >>> Message-ID: >>> Content-Type: text/plain; charset=ISO-8859-1; format=flowed >>> >>> 1) >>> stm32f103 is a thumb2 only device, and you cannot generate a rtl for >>> both <=armv5 and thumb2.
