Flash build configuration errors

Rafeeq MUHAMMED

Hello Lori,

Your reply for my last query helped me.

I am in another problem while working on debugger.

I used Digital Power Supply example project.

I could run debugging if "RAM" debugging mode is selected, unfortunately I need to change it to "FLASH" mode to increase code size.

While changing debugging mode to "FLASH" and start "Built All" i get many error messages and stop the built.

I do not understand what makes difference same code run well in RAM debugging option and not built in FLASH.

I have attached error log and screen while return built error.

Thank you.

    Hi Rafeeq,

    I'd encourage you to start a new thread for new questions instead of adding on to an answered thread so others will more easily see the new question.

    These errors are referring to floating point registers (R1H, R2H, R3H).  

    It looks like the project was intended for a floating-point build but this switch is not enabled when you change to the flash build configuration.  

    I'm not familiar with this specific code, but I would suggest checking the compiler options to see if the float support switch is enabled.  Right click on the project -> select properties -> under CPU options there should be a --float_support == fpu32.
