I'm working on a custom boot loader for a STM32F429, where I want to reserve the second of the first four 16K flash sectors for user data. Because the vector table has to start at 0x08000000, the memory layout would look like this:0x08000000 - isr ve...
I have a very peculiar problem with my STM32F745 MCU. I have generated code with CubeMX which is very basic and doesn't initialize any peripherals at all. Main simply initializes the HAL, clock & then goes into an infinite loop that increments a coun...
What is the silicon revision of the chip on currently shipping Nucleo-H7A3ZI-Q?
Posted on February 13, 2016 at 11:22Hello!I have the follow problem:I use STM32F745. I've chosen the QuadSPI interface for flash, to be exact, QSPI BANK2. I make initialization through CUBEMX, using HAL library. I see CLK signal only, there are no o...
I'm working with the h743 family and I'm trying to figure out how the HSLV (High speed Low voltage) I / O's work, because I don't want to use this option to avoid damaging the MCU, since my power supply is 3.3V. In more detail, I want to set FDCAN1 o...
While looking at datasheets of various STM32s and AN4899 (STM32 GPIO Application Note) I was trying to determine the GPIO absolute ratings. There is a consistent value of 25 mA per pin in Absolute Maximum Ratings in all datasheets, but no maximum cap...
There are examples on how to set up SDRAM on STM32F769-DISCO board but I found no comprehensive example of what I think should be the default setup for this board: SDRAM configured for heap, stack and 2MB LTDC buffer reserved.So far I figured out SDR...
So I was handed code that breaks when debugging, but to fix the breakage breaks a power control on the board. Rev A only has this problem but Rev A is what I'm stuck with . Nice, right? So I need a way to tell at run time whether the debugger is att...

Hello, I've just received the STM32L475 Discovery kit IoT node. I connected the board through USB cable to my laptop (the JP4 jumper is connected to 5V_ST_LINK) and the power supply LED (LD5) is blinking. Also the board is not visible from laptop (I ...
