Bootloader choice
I have a STM32F405RGTG MCU and want to load a bootloader on it. I am using UART and I2C and want to program it via USB-C. How do I chose the right bootloader? Does ST have original bootloaders I can use? Thank you.

Resolved! CRC32 MPEG2 configuration for ST32C0x1 CRC driver
HiI'm trying to understand how to configure the hal/peripheral to evaluate the CRC32 MPEG2 over a block of datas.I'm comparing the result with this site where as input I've used the vector 0x01, 0x01. Expected result is 0xD66FB816https://crccalc.com/...
Resolved! STM32H7 : Using the DMA to transfer burst of Can-Bus data
Looking at the FDCAN peripheral application note (AN5348), I don't see any mention of using the DMA. I'm interested in transmitting 30 8-byte messages every second via Classic-Can 2.0. Since the peripheral's FIFO isn't that deep, I was thinking of ...

STM32F4 Using FileX : Can It Be Used Independently?
Hello, community! I'm a new here .I am developing STM32F4 using STM32CubeIDE（1.14.1）, and I want to use the FileX without ThreadX. However, it seems that this is not possible in CubeMX. The FileX for the F4 series requires ThreadX, and if ignored, t...
Single word flash programming is not properly write the memory and disturbed multi write
Hi, I work in the stm32h503rbt6 controller, I use an internal clock 64Mhz and developed the Flash driver on my own and also works well in multi-word write only, single word write is not working, it is not writing the data in Flash memory(in single wo...
Resolved! 8 pulse pin outputs on the STM32F407 (Drive GPIO with basic timer?)
Hi, I have an application where I need to send send signals to 8 stepper drivers on my STM32F407 Discovery board. Each stepper driver requires an independent PULSE, DIRECTION, and SLEEP signal. DIRECTION and SLEEP are trivial GPIOs high/low. I have u...
