Hello,I've been trying to transfer some data from AXI-SRAM to DTCM via MDMA but it seems not functional.The transfer occurs the flag of end of transfer is set yet the data that I have in my DTCM isn't the orignal one contained in the AXI-SRAM.Also im...
Hello,I am facing random HardFaults on a STM32F722. They happen at various places in code, sometimes even during stack's initialization.Stack's analysis do not show any risk of overflow : most of the time, the problem happens while executing main() l...
Hi!How to set Gpio pin high while MCU is in deep sleep mode to keep power supply on?I cant find any information.
hi guys, i work on STM32 L4R5ZI without HAL functions.I use DMA for LPUART(for HMI) and SPI (for component) and I want synchronize these communication with DMAMUX. I see in the reference manual, some synchronization signals (EXTI, dmamux_evt,…), I wo...
Anyone know of any alternative hardware solution(s) from other manufacturers that is equivalent or providing similar protection features as the STSAFA100DFSPL02? Namely STSAFE.Thanks.Ref to STSAFA100DFSPL02: https://estore.st.com/en/stsafa100dfspl02-...
Hello Dear Engineers and Developers,This one is an advance question for me, perhaps as easy as ABC for you.I want to put image data on the external ram. Either of Keil or Stm32cubeIDE compilers are acceptable. I know that I should change the linker s...
I'm using smaller MCUs (L4, F3, ...), but I'd like to learn running the code from external memory.Use case: not change the MCU to the bigger one, but add external memory e.g. via QSPI.I thought this workshop is good starting point.
For IEC60335-1 class B compliance, CPU registers should function well(Should not be stuck at faults). To test those faults we need to send/store some instructions to those registers. What if those registers are stuck at fault? I mean If it is stuck a...
Hello. I have a circuit containing notably: (i) MCU pin PA2 connected to both a ULN2003 transistor-array input and a 10k pulldown resistor and (ii) the corresponding output of the ULN2003 is connected to a small beeper GND. In theory, this circuit is...
Hello,I have the RTC set for a 1 Hz interrupt. I have buttons, that when pressed, trigger a rising edge interrupt. The interrupts work fine except that when I call my button handling routine the RTC interrupts are blocked. They remain block until the...
