Did you ever get the RTC working on the STM32F0?

What do you do to get STM32_PCLK1?

Awesome, thanks!

Would you prefer a patch?

So, barthess comes into the chat, I explain him my issue, says a couple of words and BINGO, solves my issue, indirectly. I had basically forgotten to enable the backup voltage regulator, and he told me that it probably needed a special hal init case, like RTC.

So now, with only these 5 lines at the ...

I'm trying to use the Backup SRAM, the one located in the Backup Domain, at 0x40024000, (BKPSRAM_BASE), and I'm quite confused about how to go about it. This is on a STM32F4 (custom board) with working RTC on backup battery (CR2032).

I see that hal_lld_init() calls hal_lld_backup_domain_init(), but ...

I've attached the patch, which is only 2 lines really.
It may be possible to move the typedef to the config file, would that makes sense? Or maybe through some #ifdefs.
But yes, my timers are now 32-bit compatible.

I did remove the cast. Well, I now cast as a gptcnt_t instead of uint16_t, and I also changed the typedef of gptcnt_t to be a uint32_t. That actually makes it all work nice.

The only thing I can see from allowing them to be 32bit is (at least for the STM32F4 port), that gpt_lld_change_interval() casts the value to a uint16_t.

What I'm really proposing is changing gptcnt_t to be uint32_t instead of uint16_t.

Hi there!

TIM2/5 are both 32bit timers, but, from what I can see, they can't be uses as that, just as 16bit, since there's quite a few places where parameters are cast into uint16_t.

Is there any reason I can't modify code to allow the full 32bit range?

Thanks.

That bootloader is for the STM32F1, which has very different memory layout to the STM32F4, and the flash interface registers too, I decided to just basically start from scratch, leaving basically the error defines and ...
