We have a batch of custom boards using the STM32H725IGK3 and have experienced several failures getting started with them as the SWD interface appears to be fried. Initially we thought just bad luck with the first couple (inexperienced engineers or ?)...
Hi everyone,I’m working on an audio recording project using the STM32H747-DISCO board with its built-in PDM microphone. The recording works — I can clearly hear my voice — but there’s a constant background white noise in the recording. I’m trying to ...
Hello, I am reading 6.3.30 LCD-TFT controller (LTDC) section to interface with DS90C385A (LCD) or ADV7125 (VGA) Assume that LCD Clock (pixel clock) polarity is set to high. Ideally, we can expect rising edge of clock aligned to the middle of the data...
I am currently working with the STM32U5G9J-DK1 development kit interfacing with a Tianma-based display. I have successfully managed to update the display using adaptive command mode with DSI long and short write commands. However, I am encountering i...
Hi everybody,I've two cards with a STM32F446 on them.My first one works very well, the µc starts a each time.On the second card, the µc starts sometimes (I have a LED on my card that blinks at start).I've checked Vcap (2.2µF), the 3V3 rising (1ms), b...
So new problem while trying to bypass non functioning SWD...Using a working NUCLEO_H723 I can use the STM32CubeProgrammer to access it via STLINK (internal and external) as well as via USB DFU after reset with BOOT0 high.From my reading of AN2606, on...
Hi everyone,I'm encountering an issue with the STM32H747 dual-core MCU during the transition from bootloader to application. Here's a summary of the setup and observed behavior:Setup:Bootloader (CM7 core): When the BCM4 option byte is enabled, the CM...
Hello ST Expert, On our custom board - USB PD, it has 1. HW: TCPP03-M20 with STM32G0B1CBT6 2. SW: X-CUBE-TCPP 4.2.0 ( USBPD Application 4.2.0 - Dual_Role) 3. SW: Board Part tcpp0203 1.2.3 4. Tools: STM32CubeMX (6.15) & STM32CubeIDE 1.19.0 & STM32Cub...
Hi everyone,I’m working with a custom made STM32F446ZET6 board that otherwise functions perfectly (all peripherals, flash programming, etc. work fine). The only thing that doesn’t is the ROM bootloader. I can’t get USB DFU or UART boot to respond no ...
Hello All,I'm trying to keep my MSC + CDC USBX connection alive on my STM32U575. When I connect the device via USB cable, Windows Explorer opens and displays the files on the W25Q NOR Flash. I can select a file and open it from the flash. I can al...
