I have a STM32U595 with a 32.768kHz LSE oscillator.I wish to generate a 1ms/1kHz timebase with the accuracy/drift characteristics of the LSE, so naturally I went to make use of the "Hardware auto calibration with LSE (PLL-mode)" feature.Firstly, can ...

When debugging the operation of the MPU on the STM32U575 I'm confused by the apparent behaviour of the RBAR_Ax registers in the SFR window of STM32CubeIDE 1.10.1From the ARM docs I think (but I'm not 100%) that the RBAR_A1, RBAR_A2 & RBAR_A3 register...

I've burned a significant amount of time tracking down an issue, so I thought I would share in the hope of helping others and maybe improving ST's provided newlib locks.(This is probably in the wrong place, please move it as required.)I'm using the T...

Hi Jaroslav,I am sorry you are disappointed with the documentation of STM32U5 and this feature. Could you be please more specific about what kind of information you were searching for and where?Have you read the STM32U5 reference manual? There is one...

Hi Laren,Thanks for that suggestion; after updating to 1.11.2 I can now see the RLAR registers.The behaviour of the RBAR_Ax registers is still not correct (unless I am mistaken, which is very possible).For example:When I set RNR = 0x4 and set RBAR_A1...

Hi Wijeden,Thank you for your reply and for investigating this.I'm not quite sure what you mean? These are hardware registers (in an ST device) being interrogated by an ST provided debug tool, so I have little control over the address that they resid...
