We are preparing the design for a board that will be sealed in a system, so connecting a standard USB debugger to the system isn't going to be feasible. We would ideally like to place a circuit on board similar to what the various evaluation boards u...
Posted on July 11, 2018 at 22:34Trying to replicate the functionality of the project example for FatFs_uSD_DMA_RTOS on the STM32H743I_Eval board using CubeMX I have run into the next layer of problems, this one involves the SDMMC clock. There is no...
Posted on May 04, 2016 at 11:36Function returns HAL_ERR if PELOCK bit in PECR is already unlocked, so in my code I changed it into this: HAL_StatusTypeDef HAL_FLASHEx_DATAEEPROM_Unlock(void) { if (READ_BIT((*FLASH).PECR, FLASH_PECR_PELOCK)) ...
Posted on May 16, 2018 at 20:13I try to use SDMMC1 on STM32H743I Nucleo: It works fine but just if I use PLL1: PeriphClkInitStruct.SdmmcClockSelection = RCC_SDMMCCLKSOURCE_PLL;If I try to use PLL2, the PLL2R clock output via: PeriphClkInitStruct.Sdm...
Hello everyone. Can anynone please explain the steps to configure linker script to use external SDRAM? I'm using Atollic True Studio as IDE and STM32F746GDISCO as evaluation board.Thank you.
Hello there,I'm trying to implement IAP using an STM32F030K6T6. I based my code on the example provided by ST, this tutorial (http://marcelojo.org/marcelojoeng/2015/09/bootloader-on-stm32f0.html) and also reading through threads in the forum with pro...
MCU: Stm32f103c8t6i want to use Printf in my CodeCurrently i am using Hal_Uart_transmit to send data this Data when printed is correctly displayedI wanted to add printf so i have added the following to my codeBut when i use printf to send data the da...
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...
