Bootloader sometimes run slow.
Posted on May 19, 2016 at 05:12Hi: My systems run STM32F427@168 MHz using external oscillator @ 8 MHz. The system will first run boot-loader then jump to main application. I find that sometimes the boot-time is long. After check it's due to boot-l...
how to use BSP in general / IHM01A1
Posted on May 18, 2016 at 16:05Hello everybody, I am experimenting with an Nucleo-STMF030R8 and the X-Nucleo-IHM01A1 Expansion board. The example Project from STM32CubeExpansion-SPN1_V1.6.0 is working fine and i also managed to modify this Project. ...
STM32CubeMX Two VCPs using CDC
Posted on May 17, 2016 at 14:29I'm a beginner in USB Stack on STM32F4. I have a question about creating a project using CubeMX (STM32F4 Discovery) for USB CDC to have 2 Virtual Com Ports in the ''Device Manager'' ? Thanks
Operate SDMMC1 at higher clock in LP Run mode
Posted on May 16, 2016 at 08:53Hi,I am using STM32L4x6 MCU. I am trying to reduce the overall power consumption. For that I am running MCU @ 2MHz in LP Run mode. Currently the SDMMC1 transfer clock is set to 800KHz. But I want to increase while keep...
Slow transfer rate USB-HS MSC
Posted on July 17, 2015 at 00:46Hi All,I have created a project that hooks USB-HS MSC via the SDIO interface on the STM3240G devkit, I have used just the standard (unmodified) libraries. I am using cubemx v4.9.0 and F4 libraries v1.7.0The transfer r...
USB MSC low transfer speed
Posted on July 24, 2014 at 01:39Hi All,Using Cube F4 and USB MSC drivers from: ''STM32Cube_FW_F4_V1.3.0\Projects\STM324xG_EVAL\Applications\USB_Device\MSC_Standalone''.This works well, but has a transfer speed of only ~3MB/s.In comparison, using SD ...
