Hi,I am working with some custom boards for H7 and U5-series.The board schematics for STM32H735IG-DK and STM32U5A9-DISC shows both boards are using the same OCTO SPI but only the H7-board is using series resistors of 33 ohms for the all the data line...
Hello, I am following a few examples for bare metal firmware (without HAL or LL) to enable USART. I am using a NUCLEO-H745ZI-Q starting with an empty project. From the users manual I am gathering that the STLink MCU on the board provides a 25MHz (X1)...

I struggled with the difference between STM32U5G9J-DK2 and STM32U5G9J-DK1. The STM32U5G9J-DK2 link to the STM website is not working or is missing. It seems to me the STM32U5G9J-DK2 is a newer, cheaper variant, but what is the difference with DK1? I ...
There is a utility to update the EMW3080 to version 2.3.4 on the STM32H573I DISCO but how can I revert to a previous version?Is the source available for the update utility so I can replace 2.3.4 with 2.1.11?Thank you
Can somebody tell me whether I am, or not, powering this STM32H725RG in the right way?As far as I know, after reading several times the specs, the 68 pin package doesn't have LDO (SMPS only).I've built my first board this way and the MCU got burnt. ...
I just unpacked NUCLEO64 C031C6 board and .. no code is working. Debugging I found all the code was stuck at SystemClock_Config / HAL_RCC_OscConfig.I checked and by default in the ioc file the HSE and LSE are set to "Crystal/Ceramic". For now I found...
Hi,I am trying to get the above named board to work with an ILI9341 based display. But it is not working. I took a look at the SPI lines with a logic analyser. I saw that there was no activity on the CLOCK line. I switched to an alternative pin for t...
Hi,1. I bought NUCLEO-H753ZI board, but we can't find any firmware demo project for the NUCLEO-H753ZI board in downloaded "en.stm32cubeh7_v1-11-0" (Its directory "NUCLEO-H753ZI" is empty). We need the ADC firmware demo projects for NUCLEO-H753ZI b...
Hello,I try to build a 'PDO SINK' project on B-U585I-IOT02A and I have watched the video How to build an USBPD Sink application using the X-Cube-TCPP software pack - YouTube.Issue:After build project on STM32CubeMX 6.12.0 and opened project in STM32C...
