Hi,
is there anything wrong using HSE(8MHz) as RTC clock source for an L476 ? CubeMx reports a configuration error when I tried (see screenshoot). Is this a tool bug or a device limit I failed to identify reading DS+RM ? #hse #cubemx #stm32l4 #rtc- Labels:

Hello Gonzalez Laurent,
I thank you for your bug report, this is very helpful to continuously improve our SW quality.
You are absolutely right, the clock range is between 0 and 1MHz.
This will be corrected in CubeMX version 4.18.
Kind Regards
Sirma

I think that CubeMX should also be fixed to compute the values for the Async ans Sync prescalers automatically. It currently leaves them fixed to 127 and 255 respectively, regardless of the actual clock source. This is really confusing for novice users, IMHO.

Hello Cnoviello,
Yes you are right, and this is in the pipe to be corrected.
This point has been raised in another thread.
Kind Regards
