SDMMC Data Timeout Error

Posted on April 30, 2018 at 18:19HiI'm trying to write some test data to SD card by DMA with Nucleo-F767Zi.Every 100ms I write 20 blocks to SD card by calling the HAL_SD_WriteBlocks_DMA() method.I have a counter to record how many times the HAL_SD_W...

New forum lacking return links

When I make a post, I have to click at least three links to get back here. Hitting the back button only brings me to some sort of "ping timeout" page. Please either increase the timeout, or provide links back to the top. Links back to anywhere fro...

STM32L4A6VGT power consumption?

Hi,I am measuring a STM32L4A6VGT board power consumption. From the datasheet, in standby mode should be 120nA while I got the value @ 19 mA (last Friday). The FW does nothing, in main after MX_XXX init, call HAL_PWR_EnterSTANDBYMode(). Now I am gett...

I can not configure ''CubeMX SDIO DMA FatFS configuration''

Posted on September 21, 2017 at 09:26Hello!I use the microcontroller STM32F205ret6, STMCubeMX v4.22.0, Firmware vSTM32Cube_FW_F2_v1.6.0. Configured to work with SD card in SDIO + FatFs mode without DMA. Recording to the card comes at a speed of 2.5 ...

STM32 FatFS SDIO DMA bug

Posted on June 14, 2018 at 23:28How to reproduce:1) Use STM32Cube FW_F4 V1.21.0 (not tested on other versions)2) Set up SDIO 1-bit mode with default parameters.3)4) Set up FatFS with SDIO driver with default parameters.5) Set 'Use dma template'=enab...

STM32F427 and SDRAM

Hi guys,I'm using an stm32f427 interfaced with an external SDRAM by mean of FMC controller.The controller is configured with SDRAM clock period = 2 x HCLK periods and to support burst read (RBURST bit = 1).It's not clear to me how to set the RPIPE pa...

Is the "register" storage class specifier necessary in STM32 LL interfaces?

I am doing C++17 development on the STM32L4. The register storage class specifier has been deprecated for quite some time in C++ and is now forbidden. It seems to be used extensively in the STM32L4xx ADC LL interface. This causes quite a large num...

I am planning to use an STM32L4R5 series controller with LSM9DS1TR. So is there any sensor fusion library or source code available for quick integration both of them.

Reset and hold counter value on low level

Dear communityI am trying to make a timer/counter reset it's counter value on a falling edge and then hold the value until a rising edge (see attached ​picture for illustration). I am at the moment working on a L152, but I might soon be working on a ...

X-CUBE-IAP-USART problem

Hello, I'm trying to use example code provided by X-CUBE-IAP-USART package to develop IAP FW for STM32L0xx device. I'm using STM32L073 Nucleo64 board for development.When I send compiled FW using TeraTerm's YMODEM protocol nothing happens. Only thing...
