MQX 4.1 bool type conflict issues

aroste — Thu, 20 Mar 2014 13:26:25 GMT

Hi,

I am/was working on a project I did with CW10.5 and MQX 4.0.1 starting from a BSP TWR-K60F120M. The projects works fine so it's in final development part. As I still have some work and that another board software to do with the same configuration I started to update to MQX4.1.

So I installed MQX4.1 (new folder) and cloned it to my workspace to have a MQX copy with BSP from BSP TWR-K60F120M. (As I did for 2 projects now and works well)

I have some PE components that I created, as ADC; SPI; FTM; Flash, etc... I encounter the problem with bool type. I read that in PE_Types.h I should add a "#ifndef bool", that fixes most of issues. (workaround)

But I still have a type issue for 3 functions. I cannot find from where it comes, as bool is also used in some structure definitions, etc..

bool SPI_Eeprom_GetBlockReceivedStatus(LDD_TDeviceData *DeviceDataPtr)

bool SPI_Eeprom_GetBlockSentStatus(LDD_TDeviceData *DeviceDataPtr)

bool SPI1_Inc_GetBlockSentStatus(LDD_TDeviceData *DeviceDataPtr)

error: conflicting types for 'SPI1_Inc_GetBlockSentStatus'

Help would be welcome.

Check MQX_Release_Notes.pdf, section: 5.19 Bool Type Conflict in Processor Expert BSPs and MQX Applications

perhaps it will help.

Hi,

Thanks for your answer. Yes I read already that part, it's why I said that this workaround in the PE_Types.h has fixed most of error. But I still have 3 remaining errors for the functions listed above generated by PE that I don't know how to fix.

Thanks

Hi BR,

I had same issue several weeks ago so I just changed the return definition to "unsigned int" in all locations. My assumption it is a PE issue that will get resolved so this is just a workaround.

Regards,

David

Hello,

Define bool to always be an unsigned char.

At line 32 in stdbool.h, just replace #define bool _Bool by #define bool unsigned char.

You might want to make a copy of the file before because it comes with the distribution of CW.

The file is located here: "CW MCU v10.6\MCU\ARM_GCC_Support\ewl\EWL_C\include\stdbool.h"
