HI, I am using STM32H745BIT6 ST controller in my custom board.Configured in Direct SMPS mode. When the board is powered on the VCAP voltage is 1.2V and settling at 1V as expected when we try to flash the program to controller the voltage is same, but...
Greetings, I am working with the STM32U585RI and a sensor that asserts an interrupt on the MISO line. I would like to know whether this setup is feasible, and if so, how best to implement it. One approach I have considered is to use a separate pin (L...
Hi,I am testing the ECC on DTCM on the STM32H7A3ZI. At start of day I initialize all of DTCM apart from a single test location. I have a test which reads from that uninitialized location and successfully provokes the SRAM ECC interrupt, correctly r...
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 ...
Hi,I'd like to know if execution jumps to the interrupt handler of Timer x only when the CCxIF flag changes state from 0 to 1. What happens if the flag is already set and an event occurs that would have caused the flag to switch from 0 to 1 had the f...
In the documentation on STM32N657X0, it says that the memory must be connected with match length track on the boards.It says:Match length (including BGA package length)- DQS0 with IO0..7 (Byte0), all in 50 mils,- DQS1 with IO8..15 (Byte1), all in 50 ...
Hello,We have been using CANbus as our form of communication for a system with multiple nodes. Each node was individually tested with CAN and all of them work without issue. However, when we started system integration testing, we noticed significant ...
Hello ST experts,I configured an STM32H745 dual core to read data from ADC1/ADC2 in dual mode. I dedicated the M7 core to initialize ADCs, timer and DMA. But after running the code it seems that the ADC is not working either DMA. I used the similar ...
Hi ST team,Is VREFINT in STM32C011F4P6 internally fixed and stable, independent of VDDA fluctuations?If VDDA fluctuates (for example due to LDO load or battery discharge), will the ADC raw readings change proportionally because ADC reference = VDDA?I...
I am trying to create a signal that changes its frequency in dynamic way using timers but i am having some issues to do it can anyone give me some tips for easy implementation to do this task
