If you compile using trunk fpc I need to use -Cparmv7m
-Op is target cpu optimization And -cp is for choice of instruction set. The -Op seems wrong to be used in this case, project options are for defining the cpu type not if optimizations are needed. The two are listed from ppcrossarm.exe -h -Op<x> Set target cpu for optimizing, see fpc -i for possible values -Cp<x> Select instruction set, see fpc -i for possible values See what I mean, the -Op doesn't not make sense to be used from here, it should be -Cp Ideally I want to place a check box to allow the user (me) to change it from using -Op to -Cp , both are valid commands coming from using -h on the compiler. As for the arm based board , I am using a NXP LPC 1343 Risc Processor. http://www.wvshare.com/product/Open1343-Standard.htm that's the board in question Kind Regards Justin From: Michael Schnell [mailto:mschn...@lumino.de] Sent: Wednesday, 16 July 2014 6:43 PM To: lazarus@lists.lazarus.freepascal.org Subject: Re: [Lazarus] Compiler Options On 07/15/2014 05:26 AM, Justin Smyyth wrote: "Target selected as embedded" Is there an "official" description what this is supposed to mean ? Some years ago "embedded" in the Linux Kernel meant that the CPU does not feature a Memory management Unit. Nowadays, ARM CPUs without MMU seem rather outdated, while a lot of the newly designed "embedded boxes" (e.g. NAS devices) in fact do uses ARM CPUs with MMU. Hence IMHO the therm "embedded" to select a feature of an ARCH should be avoided. A -Michael
