Posted on April 24, 2018 at 16:33I am using the STM32H743xx Nucleo board with CubeMX V4.25.0 and CubeH7 V1.2.0.The HAL drivers have some issues with enabling the PLLs and individual PLL outputs (P, Q, R).1. HAL_RCC_OscConfig() always enables all PLL...
Posted on June 21, 2018 at 06:58Another issue found, potentially in HAL drivers (HAL_RCCEx_PeriphCLKConfig):I try to use PLL3R for I2C clock:PeriphClkInitStruct.I2c123ClockSelection = RCC_I2C123CLKSOURCE_PLL3; //USB will FAIL!!!If I do th...
Posted on October 30, 2016 at 14:04 Hello everyone! I tried to create a CDC to PC interchange project in Cube on STM32F103C8T6 (as you can see in attached file) and I have some kind of trouble — debug doesn't works properly. During d...
Posted on May 09, 2018 at 08:21Hi,I have designed a STM32H743II board and now I am testing hardware functionality. I have a serial FLASH connected to SPI5 which works fine. I have a serial EEPROM connected to SPI1 where I can not see any activity o...
Posted on August 03, 2017 at 19:09We are seeing a lockup issue with a STM32F746 design. On the surface it appears like a normal firmware lockup, then the watchdog triggers a reset and it recovers. But if I disable the watchdog and try to use the d...
In stm32f411RE nucleo board even with 45MHz clock with dma configuration throughput is not crossing 3-4Mbits/sec.Can any one suggest what changes need to do in the dma configuration or need to any other setting.When I checked on oscilloscope interfac...
Posted on July 13, 2018 at 00:12hi, I try to compile a minimum program using stm driver libs. but I can't compile without error about '__aeabi_uidiv' from line 1083 of stm32f0xx_rcc.c : pllclk = (HSE_VALUE / prediv1factor) * pllmull;I think the prob...
I want to make my stm32 f446re nucleo board as a mass storage device, which would be accessable via wifi. Nucleo board will be connected to esp8266 or Nodemcu.1. Will USB Renumeration feature just make my board work as a mass storage device ?2. Pleas...
