bare metal project for K60 not building

bowerymarc — Fri, 28 Feb 2014 18:04:08 GMT

I'm trying to build then k60-nfc project in KINETIS_120MHZ_SC.zip with freshly updated CW 10.5 (no license) and having a couple of problems:

First, the file fpu_asm.s wouldn't build - lots of syntax errors etc. Then I saw this thread:

problems building bare metal examples for kinetis K70

Disabling it did let the compiler complete. But, I think that's avoiding the real issue, that this project is old and it's using an old toolchain with a different assembler syntax. Just a guess. But I notice that when you make new projects, a different toolchain is used. Looks like Freescale needs to update this code.

Anyhow, so the compiler finishes, and the linker crashes with:

AppName: mwldarm.exe AppVer: 3.0.0.59 ModName: lmgr11.dll

ModVer: 0.0.0.0 Offset: 0007f841

And returns with:

mingw32-make: *** [k60-nfc.afx] Error -1073741811

I think this toolchain has some kind of bug, because on the exact same CW and computer, with the G++ lite toolchain I don't get this error. Or it's the project settings, who knows.

in {CW10.5 install folder}\MCU\bin folder, try rename the lmgr8c.dll as lmgr11.dll, and replace lmgr11.dll. can it fix the problem?

Hi Jennie,

That didn't help but I noticed there is an lmgr11.dll in the same folder as the linker (C:\Freescale\CW MCU v10.5\MCU\ARM_Tools\Command_Line_Tools) so I'm guessing it's using that one instead. So I copied over lmgr8c.dll from bin, and renamed it lmgr11.dll and that did let me compile, I just got some warnings:
