Hi.I am trying to test out a fault handler for our STM32G (right now, the fault handler just tries to determine the location of the code that caused the fault).If I force a fault (divide by zero) in "normal" non-interrupt handler code, I can easily r...
Hello, We have developed an image capturing application successfully based on STM32H7xxxx and OV7725 camera. We are now targeting to port the application to target STM32U5xxxx with the same camera. But it looks the DMA doesn't works as expected. T...
Hi,I am currently trying to update my STM32L433 on my custom board and I am having some issues with the RDP level 1.When receiving the blank boards (not programmed yet), I use a RPI with OpenOCD and a JTag to update the chip. When I set the RDP level...
Hi everyone, I’ve been stuck on a CAN communication issue between two boards: STM32F429 Discovery (Classic CAN) STM32H743XIH6 (FDCAN) I’m trying to establish CAN communication between them. Currently, the F4 board can transmit and receive data cor...
I have multiply\accumulate operations that I want to streamline by using the FMAC. For my application I will be loading the X1 buffer by DMA from peripherals and I don’t want to use circular mode. Documentation mentions ‘vector mode’ which matches wh...
In a recent design I needed an additional pin and I configured the PA13 / SWDIO pin as a GPIO input.All going fine, code works, but then this happened: After I program the chip in automatic mode and set the option byte rdp to 0xBB I can't connect aga...
Hi, I'm stuck on a problem with setting PWR_CR_VOS on NUCLEO-32 STM32L031K6- I want to select HSI16-PLL as clock source- VDD is 3.3V- FLASH latency is set to 1WSBut I can only set PWR_CR_VOS to RANGE 2 and RANGE 3.RANGE 1 cannot be selected, so I can...
Hi, We are planning to use PSRAM chip apmemory (APS12808L-3OBM) with STM32U575QII6. Please check pin assignment from STM32 to PSRAM chip And also please share the schematic and layout guidelines for STM32U575QII6 OCTASPI to PSRAM chip integration. ...
I'm using an STM32H725 to communicate with an i2c sensor. I'm using the I2C4 bus with the HAL DMA functions. I also enabled the BDMA channels for the rx and tx and respective interrupts. The problem is that the complete rx/tx callbacks are not trigge...
i use STM32N6570-DK to do a simple project but i cannot get any useful info via printf() on SWVITM data console. (1) I add some code in systemcall.c for printf() on SWVITM data console or UART1 via a "define" in my main.c. (AS many professionals sugg...
