While the Coarse calibration in RTCv2 is obsolete, in 'L1 and 'F2 it's the only method (and I know 'L1 is NRND, but it's still around and will be for years to come, if ST sticks to its commitment), and as long as it's mentioned in 'F4 it should be pr...

Through the Characteristics chapter of L78XX DS, the page break is placed incorrectly so, that the conditions - and sometimes also the first row of the table itself - is at the preceding page. Yes, it's formally OK, but is this how ST intends to pres...

(Spotted by sx107.)I know the subject is not very descriptive, but a figure is worth 1000 words:It's also in other 'H7 RMs; I leave it to ST to check them all :)(Btw. this is a carryover from the 'F7 RM, where both OTG's SOF indeed feed into TIM2 ITR...

This is new. I've used it in the past and downloaded data with no problem.Yes, I do have network connection - this post from the very same PC at the moment.JW

They are almost the same.The 'H75x has one more ADC (ADC3) than 'H7Bx, which has only 2.JW

It goes into the Default_Handler because you don't have defined the proper interrupt handler, i.e. EXTI0_1_IRQHandler() (the weak EXTI0_1_IRQHandler in the startup code, which is in that case used, is then just an alias of Default_Handler).JW

You correctly don't change the RTC settings once set up and running, but if incorrect bits in CR get set, they remain set until the next backup-domain reset (battery removal, or explicit backup-domain reset for whatever reason).> Why the odd value of...

> You think that I have RTC_CR.FMT = 1?> Where do you see it?> Is it 8403960 = 0x803BF8 above at the "CR" line?Yes.> I have corrected the TR before the jump above, I have been too slow in the debugger and copied the value after the jump. Now it is TR...
