ChibiOS Free Embedded RTOS

Posted: **Wed Oct 01, 2014 1:42 pm**

I noticed that the STM32F334 wasn't in the list of chips yet, so I started adding the necessary headers - I basically started from the STM32F30x files and the Nucleo F103RB board files, assuming that these would be closest to the desired result.

Going fine so far, but I'm hitting an error I can't quite figure out...

Code: Select all

Compiling hal.c                                                                         
In file included from ../chibios/os/hal/include/st.h:50:0,                             
                 from ../chibios/os/hal/include/hal.h:64,                              
                 from ../chibios/os/hal/src/hal.c:29:                                  
../chibios/os/hal/ports/STM32/LLD/TIMv1/st_lld.h:69:2: error: #error "TIM2 not present"
 #error "TIM2 not present"

I suspect that somewhere there's still an old path reference lurking in there?

(Feel free to add into the repo, of course - I can resubmit once this is solved)

The F334 should already be supported after the inclusion of the new headers, isn't it? you have to use the same paths of the F30x (which should be renamed to F3xx).

Ah - I was confused because there is an F30x and an F37x, so I thought the logical step would be to add F33x?

Ok, I'll try the F30x route, thanks.

F37x is a special case, it is different from the others. All other devices have the same clock tree and a common set of peripherals.

No joy, I'm still getting the "TIM2 not present" error.

Attached the board definitions I'm now using, along with these lines in my Makefile:

Code: Select all

include $(CHIBIOS)/os/hal/boards/ST_NUCLEO_F334R8/board.mk
include $(CHIBIOS)/os/hal/ports/STM32/STM32F30x/platform.mk
include $(CHIBIOS)/os/hal/hal.mk
include $(CHIBIOS)/os/hal/osal/rt/osal.mk
include $(CHIBIOS)/os/rt/rt.mk
include $(CHIBIOS)/os/rt/ports/ARMCMx/compilers/GCC/mk/port_stm32f30x.mk

# Define linker script file here
LDSCRIPT= $(PORTLD)/STM32F334x8.ld

FWIW, the "STM32F334x8.ld" file is as follows, though that point is not being reached yet:

Code: Select all

MEMORY
{
    flash : org = 0x08000000, len = 64k
    ram : org = 0x20000000, len = 12k
    ccmram : org = 0x10000000, len = 4k
}

INCLUDE rules.ld

What am I missing? I do not see any substantial differences between ST_NUCLEO_F334R8 and say ST_NUCLEO_F401RE board files.

Is the device identification macro correct?

I think so, this is in STM32F30x/cmparams.h:

Code: Select all

#if !defined (STM32F301x8) && !defined (STM32F318xx) &&                     \
    !defined (STM32F302x8) && !defined (STM32F302xC) &&                     \
    !defined (STM32F303x8) && !defined (STM32F303xC) &&                     \
    !defined (STM32F358xx) && !defined (STM32F334x8) &&                     \
    !defined (STM32F328xx)
#include "board.h"
#endif

This is in my project: #define STM32F30x_MCUCONF

And this is in ST_NUCLEO_F334R8/board.h: #define STM32F334x8

I am porting the Nucleo demos to 3.0 and did some rework on the F3 HAL, I will give F334 a try in the weekend.

Found the problem with the F334, added a demo but it is untested.

Woohoo - the demo and my test project are now compiling! Will test further soon, thank you!
