MLIB and SPI compilation error

[engineer_attila]

Hi, i have a MPC5775E-EVB .I can't use MBLIB within SPI defined project.When i just put spi configure block on this simple project, i got the error.

what causing this problem?

My Matlab version:2020a .I also made "set path" configuration for AMMCLib.

MPC5775E parameters
Compile Options: -g3 -mbig -mvle -O1 -mregnames -mlsp -specs=ewl_c9x.specs -mhard-float -Wall -c -std=c99 -fdata-sections -ffunction-sections -funsigned-char -fmessage-length=0 -nostdinc -fno-jump-tables -DTURN_ON_CPU0

Assemble Options: -g3 -mbig -mvle -mregnames -O1 -DTURN_ON_CPU0 -mhard-float

Link Options: -Xlinker -gc-sections

regards.

UPDATE

If i disable CS pin from SPI Config block , Automotive Math and Motor Control library error is dissapear. But i need to CS pin.

Indeed there are conflicts as the ArduinoRobot library already includes SPI
library.
You may remove the SPI library directory from your arduino/libraries
directory when using ArduinoRobot.
Also remove Robot_Control and Robot_Motor when not using the ArduinoRobot.

Hi Carmela, Thank you for responding my problem.That looks like weird. I completely uninstall Arduino that includes Robot_Control and Robot_Motor directories from my computer ,but nothing changed.

@mariuslucianand  Can you help me?

Hello @engineer_attila,

It looks to be something related to the compiler. The workaround I've found is to assign another CS pin in the SPI block. It can be a pin that is not used in your project.

Can you please try this workaround?

Regards,

Marius

That works, thank you @mariuslucianand.
