STM32F030F4

[etrombly]

I'm trying to set up a board for the STM32F030F4, I think I have everything correct. I wrote a quick test program to blink an led, it compiled and flashed ok, but it's not blinking. Could someone verify I set everything up right? Some of the configs I'll just post the relevant portions.

Not enough info for an answer.

Usually it can be:
- Clock settings in board.h and/or mcuconf.h.
- I/O settings in board.h.

It would also be useful to know where it stops and a stack trace.

I modified the STM32F0 discovery board and demo to the 030F4 part, so there may be some residual differences. They have the same max freq though, so the clock speed should be ok. Also with 16k of flash and 4k of ram maybe I should be trying the NIL rather than RT core.

For the board.h I just removed the extra ports that the 030F4 chip doesn't have:

looks like even though it compiled and flashed, there may still be some issues with the memory setup. I also had to disable LTO to get it to compile with the version of arm-none-eabi-gcc I'm using (5.1.0 arch linux)

It crashes but I cannot see where.

The best thing to do is to single step and see where exactly it crashes. Does it reach the main function at least?

After checking.

STM32F030x4 is not one of the supported device, it should fail to compile. Have you updated headers yourself? if so, probably there is an error in stm32_registry.h, it has to contain correct information.

No I didn't update the headers, you mean the hal_lld.h and stm32_registry.h? In my board.h I changed the MCU type to "#define STM32F030x4". It is still compiling though. I tried reflashing it again, and it's just hanging, when I interrupt it now it's stuck at the pal initialization:

Code: Select all

#0  0xfffffffe in ?? ()
#1  0x080007ec in halInit () at ../../../os/hal/src/hal.c:65
#2  0x08000b48 in main () at main.c:48

Sorry, my fault. I didn't update the board.mk when I copied it. It is not compiling now. I'm adding the 030F4 to the headers now by coping the 030F6 settings. I'll see if I can get it to work now. Thanks for the help.

I tested STM32F030x4 ever before, it needs to change #define STM32_HAS_GPIOD FALSE.

Thanks Eddie, was that with Chibios 2 or 3? I'm using 3 now. I updated stm32f0xx.h, hal_lld.h, stm32_registry.h, and made stm32f030x4.h (copied from stm32f030x6.h). I also updated the board.h and board.c to just have GPIOA, since the 030F4 only has port A. it compiles fine again, but still hangs at the pal init.

I tried stepping through to see if I could get more specific on what is failing, but no luck:

It was with Chibios 3. In attachment is my working project.
