Resolved! RTC: are interrupt flag set during Vbat mode
I have a STM32U595 and I use the RTC in binary mode.If an SSR underflow occurs during Vbat mode, will the SSRUF be set so after power recovery I can manage the interrupt ?

Resolved! Any limits on flash selection for STM32N6
From my understanding all STM32N6 chips need a external flash chip and there's a static stage 0 boot loader. So if this is true is there any limitation's on the brands of flash or speed/address bit size limitations? With the previous stage 0 bootloa...
Using external RAM with STM32U5G9-HSPI
Hi Everyone,I am working on a project with TouchGFX. I'm working with STM32U5G9ZJT6 and I have an external RAM APS12808L-OBM-BA connected via HSPI (Fclk-hspi 100 MHz) in mapped mode. The project is working, but the image animation are not working wel...
Resolved! RM0456 discrepancy in ADC oversampling right shift
In the RM0456 at 33.4.31 Oversampler it say:The division coefficient M consists of a right bit shift up to 10 bits, and is defined using the OVSS[3:0] bits in the ADC_CFGR2 register.But at 33.6.5 ADC configuration register 2 (ADC_CFGR2), it allow up ...
Resolved! STM32H7S7L8H6H XSPI instability
IssueHigher ambient temperatures cause communication malfunctions with XSPI memories.DetailsOur design is heavily adopted from STM32H7S78-DK which also has the same issue described below.The application uses memory-mapped mode for both Flash and RAM ...
Resolved! RTC hrtc.Init.AsynchPrediv & hrtc.Init.SynchPrediv = 10 Registers
Can somebody please help me. The code below is initializing the RTC. The clock works I can set and read time and date no problem. Somehow if I change these register: hrtc.Init.AsynchPrediv = 131; hrtc.Init.SynchPrediv = 10; It has no imp...
ADC "shorting" analog input to GND
We're using the following circuit to measure a battery voltage @ 20 kHz for use in motor control.We are having some issues though, where the ADC suddenly starts measuring 0 V (0 in the data register) and gets locked in this state. In this state, we a...
Resolved! STM32U5 FATFS with FreeRTOS
Hi,I'm attempting to write to an SD Card using a Riverdi STM32U5A9 display board. Since TouchGFX natively uses FreeRTOS, I'm attempting to keep it within FreeRTOS. Porting to ThreadX has caused it's own issues which I have in a separate thread. In...
Resolved! STM32G071GBUx Bootloader Setup Problem
Hi, I am trying to configure my STM32G071GBU6 to enable reprogramming the flash throguh USART1. I check the datasheet of STM32G071x8/xB, reference manual RM0444, and application note AN2026. It says I am supposed to configure the PA9 (USART1_Tx) and...
PWM jitter on a home made card
Hello everyone, Some time ago I asked on this website information about jitter on a PWM : Solved: PWM jitter - STMicroelectronics CommunityThe problem was that when generating a PWM, it wasn't very stable. At the time changing the source clock to the...
