Hello there, I'm playing with the NUCLEO-H743ZI2 board and having difficultis with PTP. When TSIE (MACIER is set the interrupt is getting retriggered endlessly. I've tried to clear TSIS by reading both MACISR as well as MACTSSR (TXTSSIS bit set). The...
i, I am using STM32C092CCT6 with FDCAN.I transmit one CAN frame every 100 ms (even tried 50 ms).But on the receiver side, I always receive frames only every ~497 ms.It looks like something is delaying or buffering the frames.What I want to know:Which...
This previous thread refershttps://community.st.com/t5/stm32-mcus-products/stm32f4xx-does-going-up-a-package-pin-count-impact-pin-af/td-p/862282The 437 is curiously a very close superset of the 417. Apart from the extra 64k RAM, the only difference i...
Hello, I want to design a PCB with STM32H743VIT6 MCU. But I am not sure how can I choose crystal and capacitors properly. In STM32H743VIT6 datasheet there is one section about this topic;according to this information should I take the Cstray value as...
Hi We are using an STM32U073CCT6 on a battery-powered board. We need to put the processor in low-power mode to increase battery life. The current in STOP MODE 2 is about 20uA. To address some issue related to the power supply and our hardware, we put...
Hi,I am currently working on the firmware of a PCB with an STM32G031K8T6 as the MCU, supplied by a 1.8V voltage.When I enter Stop 1 mode, the consumption of the MCU drops to 100uA, instead of the 7uA stated in the datasheet.The app_stop function is a...
My target is a 144 pin version of the STM32H5.I would like to implement both a JTAG and a FMC interface.More specifically, a 24-bit muxed-PSRAM.And I would like to output the Byte enable signals.However on this package size, there is only one possibl...
Hello,I'm new to this STM32 products. We designed custom module with STM32F103CBT6TR. We are facing issue with serial boot loader.I'm using CH340 UART to USB converter module. CH340 MOD TX --> Our Module's RXCH340 MOD RX --> Our Module's TXCH340 MOD ...
From the ES0335 errata there are two errata that look pretty significant for dual bank boot (which I'm planning to use as the basis of field firmware update):2.2.8 Dual-bank boot not working when the boot in flash memory is selected by BOOT0 pinDesc...
I have an I2C device that only operates with 1.8V logic (Pins are not 3.3V tolerant) that I want to connect to the STM32N6. I don't want to add an I2C redriver if I can avoid it. I want to keep as many of my I/O pins on the STM32N6 powered from 3.3...
