Problem building MQXLite with GNU Arm Embedded build chain

[jwiblin]

Hi there.

I am trying to build mqx lite using the GCC arm build chain for a KL25Z target. I am using the processor expert driver suite plugin 10.4 with Eclipse Kepler.

I encounter problems when it comes to building the assembly files. With boot.S i have the followings errors:

'Building file: ../MQXLITE/psp/cortex_m/core/M0/boot.S'

'Invoking: Cross GCC Assembler'

It seems like the assembly instructions used in this file is not compatible with the gcc compiler however it is my understanding that the code generated by the plugin should be compatible with gcc/gnu?

Thanks

Hi James,

Thank you for share your solution :smileywink:

Have a great day,

I think i might of fixed this. I was setting up the build environment using this tutorial: DIY Free Toolchain for Kinetis: Part 4 – Processor Expert for Eclipse | MCU on Eclipse but when i create a new PEx project and leave the build settings alone it builds fine.
