Posted on July 31, 2017 at 15:36Hi,I'm using STM32F303VB in my custom hardware that requires boot loading STM32 over CAN. I'm writing a CAN boot loader.I want to know, how to switch/jump from boot loader to application?Is there any document or proje...
Posted on August 17, 2017 at 16:23I am using hal lib.When I cut can transmission between microcontrollers.It is stuck in this function:HAL_GetTick() currently get same value because systick interrupt not working so the value systick increase every t...
Posted on August 17, 2017 at 03:08Previous Post Title:Help me ST community... you're my only hope. STM32F0 'resets' (???) on interrupt?I wrote most of this earlier today, but have since then solved the problem. After 5-6 days of experiencing prob...

Posted on October 11, 2016 at 12:19First: I do not use USB MSD and FatFS at same Time, but they work on the same SD-Card. This SD-Card is connected via SDIO with 4 Bit Databus. I use a STM32L476 but I think the Problems should be identical for all S...
Posted on August 15, 2017 at 15:12 Hi, I am using a Nucleo F401RE running at 84 MHz (8 MHz XTAL PLL'd up to 84 MHz) and then using Timer 2 as a simple counter to count how long it takes to run the delays. Timer 2 is set to run at 84 MHz with n...
Posted on August 10, 2017 at 21:11We need software written that implements a STM32F407 host mode USB driver, able to connect and communicate with USB serial devices that expose multiple virtual devices such as GSM/GPRS modems or Telit.I wanted to ge...
Posted on August 11, 2017 at 22:33 I have been playing with 4bit SDIO and FatFS. I was able to get good write speeds (8-9 MB/s) but i would often get errors and the SD card lock up. No read/write. Project is CUBE 4.0 generated for the STM32...
Posted on August 14, 2017 at 07:31Greetings,I generate the project using To control the bldc motor with hall sensors interface. The configuration is as below:Refer to TIM4, which is set as the hall sensor interface, the detail configuration is as be...
Posted on July 28, 2017 at 07:56Greetings,I am rolling my own USBD DFU bootloader for an STM32F427. I have a CubeMX project reading and writing to Internal Flash. Now I need to expose the OTP memory region, similar to the System Memory USBD DFU boot...
