Nucleo F030 broken on mbed builds 102 and onwards.

[campag]

Last revision that works is 101. After that, even simple LED blinky code does not run. Paul Staron pinpointed the problem here:

Paul points I believe to gcc arm startup, but you are having problem with the online ide or offline using keil, is that correct?

[campag]

Correct, I'm using the online complier.

Sorry guys wrong file. Check the question link again for the fix. If I add that part back to the latest revision it works. I have a resolve for the RTC reset bug on this target as well as the F401.

Hello,
I just used the online compiler, nucleo_blink_led example, and NUCLEO_F030R8 platform.
I have tested mbed library revision 102 and 108. Both are blinking the led.
Same behavior with KEIL debugger
Kind regards

Is that with external crystal set up? I have checked now using MBED-SRC revision 627 (current) with external crystals fitted and it is not working. Was working (and still does) before the changes mentioned.

My Nucleo-F030R8 uses the HSI oscillator: no HSE crystal, nor MCO 8MHz solder bridges. I've just re-tested LED blinky code:

MBED-SRC 627 is not working for me. As Paul/star297 has identified, 582 is the last revision working here.

MBED lib 102-107 is not working here (can't see 108?), 101 is OK.

Have a blinking LED again after today's mbed-src 630 update. However, it's about 4x faster than it should be. Edit: the blink rate is more like 6x too fast.

[star297]

Just tried with rev. 634 and as you say running too fast.
Using HSE 8MHz crystal.

@dinau Is this fixed?

[dinau]

Hi 0xc0170,
I've checked a simple LED blinky and printf() code using latest SDK srcs.
It's ok, works well.
