Resolved! STM32H573 VFQFPN68 exposed pad details
Hello,We are using the STM32H573 in a new project. We have designed a custom board using the 64-pin LQFP package.The MCU connects to a ethernet PHY using RMII interface.Our product has to meet strict radiated emissions levels that are 7dB lower that ...
STM32L432KBU6TR SPI 16 bit mode issue
STM32L432KBU6 L432 chip, spi3, 16bit mode, 20M baud rate, spi output sclk is 16 cycles when it is powered on again after working for a period of time. Sometimes 15 cycles, sometimes 17 cycles, sometimes 16 cycles are output again. This will help conf...
Resolved! SMPS Configuration for STM32H7
I've designed a custom board using the STM32H747I MCU, following the STM32H747I-DISCO reference design. In my design, I've connected VLXSMPS to VDDLDO, similar to the reference design. I'm currently setting up the power configuration in STM32CubeIDE ...
Resolved! STM32F407 Discovery Board UART1 not working
I'm having the same problem on 2 different boards. I gen'd up a simple program using CubeMX and I'm only sending some data to both ports at the same time: void StartTask02(void const * argument) { /* USER CODE BEGIN StartTask02 */ /* Infinite loo...
Resolved! Does the STM32L051 have any unpublished errata for the EEPROM?
Does the STM32L051 have any unpublished errata for the EEPROM?The STM32L151 has an errata note that an EEPROM write while the MCU gets reset could look it up. Is the same true for the STM32L051? STM32L051 does not mention anything in the errata. But ...
Resolved! SDMMC2 on STM32H755 Nucleo PB14 Reserved
Hi folks,I have SDMMC1 working on CM7 on my H755 Nucleo. Now I want to migrate FAT-FS and the uSD to CM4, in which case I think I should switch to the SDMMC2 peripheral since it's in D2 domain along with CM4.I have a some questions about this and wou...
USB trace impedance for STM32H725
I am laying out a USB for a STM32H725. I would like clarification on something out of the datasheet (DS13311).Note 2 under table 118 states: No external termination series resistors are required on USB_DP (D+) and USB_DM(D-); the matching impedance i...
Resolved! NUCLEO-H7S3L8 USB-HS & XSPI problems
I have several problems with the NUCLEO-H7S3L8 board 1) When initializing the USB - HS peripherals, I getting stuck in the "USB_CoreReset" function: Related problem and after some time when (count > HAL_USB_TIMEOUT) the program goes to Error_Han...
Resolved! STM32U585 MPU cacheability?
I am using an STM32U585QI. I have some memory mapped PSRAM that I'm using. I have enabled DCACHE, but do I have to manually do something with the MPU for it to cache memory accesses to/from the memory? The reference manual says:"In addition, the A...
