BUG: CubeMX-generated code fails to compile...

[Dave Nadler]

I regenerated files with latest CubeMX and the generated code fails to compile. Regeneration was done to incorporate a few settings changes and the latest pack for this processor; previously code generated was OK. Errors below, and I've attached the IOC file and the offending "C" source generated by CubeMX.

Any ideas what's going on?

Anybody at STM?? @Nawres GHARBI​ ? @Sara BEN HADJ YAHYA​ ?

Are you able to rebuild the project from the IOC file and reproduce this bug?

Thanks!

Best Regards, Dave

"regenerated..." not clear; so same code was working before

?

[Dave Nadler]

@AScha.3​  Clarified above: Regeneration was done to incorporate a few settings changes and the latest pack for this processor; previously code generated was OK.

What version of FreeRTOS and CMSIS-RTOS are you using?

[Dave Nadler]

@CMArtínez​  CMSIS_V1 and CMSIS_V2 (selected in attached IOC) both fail.

FreeRTOS version as generated from CubeMX is 10.3.1

Random "developers" writing things. What are the odds of creating something decent and reliable that way? 😉

Anybody at STM?? @Nawres GHARBI (ST Employee)​ ? @Sara BEN HADJ YAHYA (ST Employee)​ ?

Are you able to rebuild the project from the IOC file and reproduce this bug?

Thanks!

Hello @Dave Nadler​ 

First let me thank you for posting.

I downloaded the *.ioc and the .c file and I have used them to generate a project using the CubeMx 6.6.1 and the CubeIDE 1.10.1.

The project compile without errors.

But I want to mention that the after looking at the compilation log you have provided I found that it is showing an error about some undeclared variables that are note present in the CubeMx generated code (perhaps they are from the code you added later)

../FATFS/Target/sd_diskio.c: In function 'BSP_SD_AbortCallback':

../FATFS/Target/sd_diskio.c:675:4: error: 'msg' undeclared (first use in this function)

 675 |  msg = RW_ABORT_MSG;

   |  ^~~

../FATFS/Target/sd_diskio.c:675:4: note: each undeclared identifier is reported only once for each function it appears in

../FATFS/Target/sd_diskio.c:675:10: error: 'RW_ABORT_MSG' undeclared (first use in this function)

 675 |  msg = RW_ABORT_MSG;

Try to check the "BSP_SD_AbortCallback" function.

I will be waiting for your feedback.

Kind regards,

Semer.
