debug build of BSP

While trying to diagnose a problem I have been stepping into some BSP functions and it appears that the build is optimised. I get the usual weirdness single stepping the debugger through optimised code...

So, it turns out to be a bit complicated to make a debug build of the BSP - if I make the compiler setting '-g3' in BSP prefs the BSP link fails.

Is there an easy way to switch back and forth for the BSP?
(eg between '-g0' and '-g3' for gcc?)

Hi Happy Heyoka,

This question appears to be related to the Xilinx tools rather than MicroZed or ZedBoard specifically. Please direct these types of tools questions to the Xilinx forums where you are more likely to get a response from the Xilinx experts.

You should be able to override the optimization settings by appending an optimization flag (-O0 --> which is read hyphen, capital Oh, zero) to the extra_compiler_flags field. This works okay for me to build the BSP in SDK. Take a look at this forums post for further information:

As for switching between a release BSP and a debug BSP, one thing that I do is to create two identical BSPs but set one to build with no optimization. You can then change the referenced BSP for your application by right-clicking on the SDK project and selecting "Change Referenced BSP" menu option.

Regards,

-Kevin

with the two BSPs; I will play with that.

I'll try searching Xilinx forums also.
